Code for passing data between activities in Android :

ActivityOne.java


String value = "Hello!";
Intent in = new Intent(this,ActivityTwo.class);
in = putExtra("Key", value);
startActivity(in);

ActivityTwo.java


Bundle bundle = getIntent().getExtras();
String valueReceived = bundle .getString("Key");

 

Code for passing multiple data or values between activities in Android :

Method 1 : Using Intent to pass data and Bundle to extract data between activities in Android

ActivityOne.java


String value1 = "Hello!";
String value2 = "Hi!";
Intent in = new Intent(this,ActivityTwo.class); 
in = putExtra("Key1", value1); startActivity(in); 
in = putExtra("Key2", value2); startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String valueReceived1 = bundle .getString("Key1");
String valueReceived2 = bundle .getString("Key2");

 

Method 2 : Using Bundle to pass and to extract data between activities in Android

ActivityOne.java


String value1 = "Hello!";
String value2 = "Hi!";
Intent in = new Intent(this,ActivityTwo.class); 
Bundle bundle = new Bundle();
bundle.putString("Key1", value1);
bundle.putString("Key2", value2);
in = putExtras(bundle); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String valueReceived1 = bundle .getString("Key1");
String valueReceived2 = bundle .getString("Key2");

 

Code for passing array between activities in Android :

ActivityOne.java

String[] array = new String[]{"Item1", "Item2", "item3", "Item4", "item5"};
Intent in = new Intent(this,ActivityTwo.class); 
Bundle bundle = new Bundle();
bundle.putStringArray("MyArray", array);
in = putExtras(bundle); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String arrayReceived[] = bundle.getStringArray("MyArray");

 

Code for passing ArrayList between activities in Android :

ActivityOne.java

ArrayList<String> array = new ArrayList<String>();
array.add("Hello");
array.add("Hi");
array.add("Bye");
Intent intent = new Intent(this, ActivityTwo.class);
intent.putExtra("array_list", array);
startActivity(intent);

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
ArrayList<String> array = (ArrayList<String>) bundle.getStringArrayList("array_list");
