Android passing multiple data from one activity to another

Sometimes you may have problems to pass an Id, a form data with multiple values from one activity to another in Android. But this post completely solves your problem. This is achieved easily by using class Intent and bundle. Class Intent is responsible for starting an activity. Also, we will use the two methods, I.e, putString() contains the Id and the String value to be passed and putExtras() that contains the bundled value to be passed as shown below.

         MainActivity.java


                  Intent intent=new Intent(MainActivity.this, Activity2.class);                   Bundle extras = new Bundle();                   extras.putString("NameId", "Peter");                   extras.putString("ContactId", "+08823443");                   intent.putExtras(extras);                   startActivity(intent);


Besides, you can use Bundle with variables as shown below.
       
Bundle with Variables

                  String name="Peter";                   String contact="+08823443";                   Intent intent=new Intent(MainActivity.this, Activity2.class);                   Bundle extras = new Bundle();                   extras.putString("NameId", name);                   extras.putString("ContactId", contact);                   intent.putExtras(extras);                   startActivity(intent);



Activity2.java

For the second activity, we will use Bundle to get the passed Id and get the value passed by that ID as shown below.

         Bundle extras = getIntent().getExtras();           String name = extras.getString("NameId");           String name = extras.getString("ContactId");

Our final output will be Peter and +08823443.



Passing Integer Values
 For the case of an integer, use the following code to pass multiple integer values.

MainActivity.java

        Intent intent=new Intent(MainActivity.this, Activity2.class);         intent.putExtra("intVariableName", intValue);         startActivity(intent);

Activity2.class
Activity2.java, use the following code to receive integer values from the MainActivity.java

 Intent mIntent = getIntent();  int intValue = mIntent.getIntExtra("intVariableName", 0);


Congrats:Now you can pass multiple Strings and Integers from one class to another.

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 th...
