Android Custom Vertical Dropdown Icons Menu

https://www.viralandroid.com/2016/01/android-custom-vertical-dropdown-icons-menu.html

In this tutorial, I am going to show how to create custom vertical dropdown icon menu in android programmatically. Creating and implementing custom menu is not so difficult in android because we can make such menu with XML and to make perfectly working we have to add little bit java code in our app activity file.

We can create and implement drop down icons menu in android only using one XML layout file and a java activity file. But to add some extra effect like animation, hover color, etc. we have to create some XML file in drawable folder or you can add some code in java activity file.

Here, you will learn not only to implement drop down custom icon menu in your android application but also learn to add onClick event to the icon and to add on press or focus color to the icon background.

Let’s start step by step implementing dropdown icon menu in android application. Following are the different XML and java file.

XML Layout File

Following is the XML layout file where I have added ImageButton and TextView inside LinearLayout and RelativeLayout with some important attributes.

Java Activity File

Following is the modified code of java activity file where I have added onClick event to show and hide dropdown icon menu.

src/VerticalDropDownIconMenu.java

// Creating Android Custom Vertical Dropdown Icons Menu Using XML
package viralandroid.com.androidxmluserinterfacetutorial;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.LinearLayout;

public class VerticalDropDownIconMenu extends AppCompatActivity {

    LinearLayout dropDownMenuIconItem;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.custom_vertical_dropdown_icon_menu);

        dropDownMenuIconItem = (LinearLayout) findViewById(R.id.vertical_dropdown_icon_menu_items);
    }

    public void verticalDropDownIconMenu(View view) {
        if (dropDownMenuIconItem.getVisibility() == View.VISIBLE) {
            dropDownMenuIconItem.setVisibility(View.INVISIBLE);
        } else {
            dropDownMenuIconItem.setVisibility(View.VISIBLE);
        }
    }

    public void menuItemClick(View view) {
        dropDownMenuIconItem.setVisibility(View.INVISIBLE);
    }
}

For implementing on pressed color in icon background I have create onclick_press_color.xml file inside res/drawable directory. Following is the content of onclick_press_color.xml file.

res/drawable/onclick_press_color.xml

	<?xml version="1.0" encoding="utf-8"?>
	<selector xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:drawable="@color/black" android:state_focused="true" android:state_pressed="true" />
	<item android:drawable="@color/black" android:state_focused="false" android:state_pressed="true" />
	<item android:drawable="@color/light_black" />
	</selector>

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.
