How to pass variables to another activity in android?

create and object of intent and send your data throw putstring() or putExtra() methods

 Intent intent = new Intent(this, YourClass.class); intent.putString("key1", var1);// if its string type Intent.putExtra("key2", var2);// if its int type startActivity(intent); 

on receiving side

Intent intent = getIntent(); String var1 = intent.getStringExtra("key1"); int i = var2.getIntExtra("key2", 0); 

Send data from MainActivity to Activity2 using:

Intent activity2 = new Intent(MainActivity.this, Activity2.class); activity2.PutExtra("MyData", "Data from Activity1"); StartActivity(activity2); 

Receive data in Activity2 using:

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); .............. .................. if( getIntent().getExtras() != null) { String myData = getIntent().getStringExtra("MyData"); } ............... ..................... } 

FirstActivity

Intent intent = new Intent(this, Example.class); Bundle mBundle = new Bundle(); mBundle.putString(key, value); intent.putExtras(mBundle); startActivity(intent); 

SecondACtivity

String value = getIntent().getStringExtra(key); 

You can also pass you values in bundle also

FirstActivity.java

Intent mIntent = new Intent(this, Example.class); Bundle mBundle = new Bundle(); mBundle.putString(key, value); mIntent.putExtras(mBundle); startActivity(mIntent ) 

SecondActivity.java

String value = getIntent().getExtras().getString(key) 

Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes.

I think this will help you..

You can make this with a static variable.

MainActivity.java

public static String nameVariable= "Text"; 

SecondActivity.java

String textFromMainActivity = MainActivity.nameVariable;
