[Solved] Bundle.putInt() , how does it work?

by


1) You can share int with other activity like this :

String YOUR_KEY = "id";
Intent intent = new Intent(getApplicationContext(), DisplayContact.class);
intent.putExtra(YOUR_KEY, id); 
startActivity(intent);

or

Bundle dataBundle = new Bundle();
dataBundle.putInt(YOUR_KEY, id);
intent.putExtras(dataBundle);

2) And get int in your activity like that :

int defaultValue = 0;
int id = getIntent().getIntExtra(YOUR_KEY, defaultValue);

or

Bundle extras = getIntent().getExtras(); 
int id = extras.getInt(YOUR_KEY);
