TabLayout Tutorial With Example In Android Studio

Example 1 of TabLayout:
Below is the first example of TabLayout in which we display three non-sliding tabs. In this example we define a TabLayout and a FrameLayout in our xml file. In this example we create and add 3 tabs in the TabLayout with the help of different methods of TabLayout. After that we implement setOnTabSelectedListener event and replace the FrameLayout with the fragment’s according to selected tab.
TabLayout Example in Android Studio
Step 1: Create a new project and name it TabLayoutExample
Step 2: Open build.gradle and add Design support library dependency.
apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "com.abhiandroid.tablayoutexample"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0' // design support library
}
Step 3:  Open res -> layout ->activity_main.xml (or) main.xml and add following code:
In this step we add the code for displaying TabLayout and ViewPager in our xml file.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">

<android.support.design.widget.TabLayout
android:id="@+id/simpleTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="@android:color/darker_gray"
app:tabIndicatorColor="#f00"
app:tabSelectedTextColor="#f00"
app:tabTextColor="#000" />

<FrameLayout
android:id="@+id/simpleFrameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" />

</LinearLayout>
Step4: Open   src -> package -> MainActivity.java
In this step we open MainActivity and add the code for initiate the FrameLayout and TabLayout.  After that we create and add 3 tabs in the TabLayout. Finally  we implement setOnTabSelectedListener event and replace the FrameLayout with the fragment’s according to selected tab.
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.widget.FrameLayout;

public class MainActivity extends AppCompatActivity {

FrameLayout simpleFrameLayout;
TabLayout tabLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// get the reference of FrameLayout and TabLayout
simpleFrameLayout = (FrameLayout) findViewById(R.id.simpleFrameLayout);
tabLayout = (TabLayout) findViewById(R.id.simpleTabLayout);
// Create a new Tab named "First"
TabLayout.Tab firstTab = tabLayout.newTab();
firstTab.setText("First"); // set the Text for the first Tab
firstTab.setIcon(R.drawable.ic_launcher); // set an icon for the
// first tab
tabLayout.addTab(firstTab); // add  the tab at in the TabLayout
// Create a new Tab named "Second"
TabLayout.Tab secondTab = tabLayout.newTab();
secondTab.setText("Second"); // set the Text for the second Tab
secondTab.setIcon(R.drawable.ic_launcher); // set an icon for the second tab
tabLayout.addTab(secondTab); // add  the tab  in the TabLayout
// Create a new Tab named "Third"
TabLayout.Tab thirdTab = tabLayout.newTab();
thirdTab.setText("Third"); // set the Text for the first Tab
thirdTab.setIcon(R.drawable.ic_launcher); // set an icon for the first tab
tabLayout.addTab(thirdTab); // add  the tab at in the TabLayout


// perform setOnTabSelectedListener event on TabLayout
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
// get the current selected tab's position and replace the fragment accordingly
Fragment fragment = null;
switch (tab.getPosition()) {
case 0:
fragment = new FirstFragment();
break;
case 1:
fragment = new SecondFragment();
break;
case 2:
fragment = new ThirdFragment();
break;
}
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.simpleFrameLayout, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();
}

@Override
public void onTabUnselected(TabLayout.Tab tab) {

}

@Override
public void onTabReselected(TabLayout.Tab tab) {

}
});
}
}
Step 5: Now we need 3 fragments and 3 xml layouts for three tabs. So create three fragments by right click on your package folder and create classes and name them as FirstFragment, SecondFragment and ThirdFragment and add the following code respectively.
FirstFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FirstFragment extends Fragment {

public FirstFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_first, container, false);
}

}
SecondFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SecondFragment extends Fragment {

public SecondFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_second, container, false);
}

}
ThirdFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class ThirdFragment extends Fragment {

public ThirdFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_third, container, false);
}

}
Step 6:  Now create 3 xml layouts by right clicking on res/layout -> New -> Layout Resource File and name them as fragment_first, fragment_second and fragment_third and add the following code in respective files.
Here we will design the basic simple UI for all the three tabs.
fragment_first.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="First Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>
fragment_second.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Second Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>
fragment_third.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Third Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>

Example 2 of TabLayout Using ViewPager:

Below is the example of TabLayout in which we display sliding tabs with the help of ViewPager. In this example we define a TabLayout and a ViewPager in our xml file. In this example we create and add 3 tabs in the TabLayout with the help of different methods of TabLayout. After that we create a PagerAdapter to set up the TabLayout with ViewPager.
TabLayout Example in Android Studio
Step 1: Create a new project and name it TabLayoutExample
Step 2: Open build.gradle and add Design support library dependency.
apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "com.abhiandroid.tablayoutexample"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0' // design support library
}
Step 3:  Open res -> layout ->activity_main.xml (or) main.xml and add following code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">

<android.support.design.widget.TabLayout
android:id="@+id/simpleTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="@android:color/darker_gray"
app:tabIndicatorColor="#f00"
app:tabSelectedTextColor="#f00"
app:tabTextColor="#000" />


<android.support.v4.view.ViewPager
android:id="@+id/simpleViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</LinearLayout>
Step 4: Open   src -> package -> MainActivity.java
In this step we open MainActivity and add the code for initiate the ViewPager and TabLayout.  After that we create and add 3 tabs in the TabLayout. Finally we set an Adapter named  PagerAdapter to set up the TabLayout with ViewPager.
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

ViewPager simpleViewPager;
TabLayout tabLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// get the reference of ViewPager and TabLayout
simpleViewPager = (ViewPager) findViewById(R.id.simpleViewPager);
tabLayout = (TabLayout) findViewById(R.id.simpleTabLayout);
// Create a new Tab named "First"
TabLayout.Tab firstTab = tabLayout.newTab();
firstTab.setText("First"); // set the Text for the first Tab
firstTab.setIcon(R.drawable.ic_launcher); // set an icon for the
// first tab
tabLayout.addTab(firstTab); // add  the tab at in the TabLayout
// Create a new Tab named "Second"
TabLayout.Tab secondTab = tabLayout.newTab();
secondTab.setText("Second"); // set the Text for the second Tab
secondTab.setIcon(R.drawable.ic_launcher); // set an icon for the second tab
tabLayout.addTab(secondTab); // add  the tab  in the TabLayout
// Create a new Tab named "Third"
TabLayout.Tab thirdTab = tabLayout.newTab();
thirdTab.setText("Third"); // set the Text for the first Tab
thirdTab.setIcon(R.drawable.ic_launcher); // set an icon for the first tab
tabLayout.addTab(thirdTab); // add  the tab at in the TabLayout

PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
simpleViewPager.setAdapter(adapter);
// addOnPageChangeListener event change the tab on slide
simpleViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
}
}
Step 5: Create a new Class named PagerAdapter and extend FragmentStatePagerAdapter in the class. In this step we create a PagerAdapter class and extends FragmentStatePagerAdapter In the class for setting the TabLayout with the ViewPager.
package com.abhiandroid.tablayoutexample;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;

public class PagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;

public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}

@Override
public Fragment getItem(int position) {

switch (position) {
case 0:
FirstFragment tab1 = new FirstFragment();
return tab1;
case 1:
SecondFragment tab2 = new SecondFragment();
return tab2;
case 2:
ThirdFragment tab3 = new ThirdFragment();
return tab3;
default:
return null;
}
}

@Override
public int getCount() {
return mNumOfTabs;
}
}
Step 6: Now we need 3 fragments and 3 xml layouts for three tabs. So create three fragments by right click on your package folder and create classes and name them as FirstFragment, SecondFragment and ThirdFragment and add the following code respectively.
FirstFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FirstFragment extends Fragment {

public FirstFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_first, container, false);
}

}
SecondFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SecondFragment extends Fragment {

public SecondFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_second, container, false);
}

}
ThirdFragment.class
package com.abhiandroid.tablayoutexample;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class ThirdFragment extends Fragment {

public ThirdFragment() {
// Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_third, container, false);
}

}
Step 7:  Now create 3 xml layouts by right clicking on res/layout -> New -> Layout Resource File and name them as fragment_first, fragment_second and fragment_third and add the following code in respective files.
Here we will design the basic simple UI for all the three tabs.
fragment_first.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="First Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>
fragment_second.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Second Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>
fragment_third.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="info.androidhive.materialtabs.fragments.OneFragment">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Third Fragment"
android:textSize="40dp"
android:textStyle="bold" />

</RelativeLayout>

how to retrieve image from sqlite database in android and display in listview

 Android platform provides several ways to store data in our application. 1. SQLite database 2. SharedPreferences etc For our post, we will only work with SQLite database. First and foremost, we need to understand what an SQLite database is? SQLite database  is an open source SQL database that stores data to a text file on a device. It executes SQL Commands to perform a set of functions, that is, create, read, update and delete operations. On my previous post, I showed how to  store data in SQLite database from edit text, retrieve and populate it in a listview . For this post, I will show the SQLite CRUD operations with images from gallery and text from EditText. We need to understand this; images are stored in SQLite database as BLOB data type. A BLOB is a large binary object that can hold a variable amount of data.  Note, we can only store images in the database as BLOB data type. We need to convert our image path to a bitmap then to bytes. Also
