When start a new activity in our main activity using startActivity(), data can be passed using Bundle.
Inside the main activity, MainActivity.java
Get the data in onCreate() of the new activity, NewActivity.java
The code this.getIntent().getExtras() return the map of all extras previously added with putExtra(), or null if none have been added.
Inside the main activity, MainActivity.java
Intent intent = new Intent(); intent.setClass(MainActivity.this, NewActivity.class); Bundle bundle = new Bundle(); bundle.putCharSequence("extraCharSequence", "hello"); bundle.putInt("extraInt", 12345); //... intent.putExtras(bundle); startActivity(intent);
Get the data in onCreate() of the new activity, NewActivity.java
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Bundle bundle = this.getIntent().getExtras(); CharSequence dataCharSequence = bundle.getCharSequence("extraCharSequence"); int dataInt = bundle.getCharSequence("extraInt"); };
The code this.getIntent().getExtras() return the map of all extras previously added with putExtra(), or null if none have been added.
