推荐答案

例如：

在MainActivity：

In MainActivity :

Intent intent = new Intent();
intent.setClass(this, Other_Activity.class);
intent.putExtra("EXTRA_ID", "SOME DATAS");
startActivity(intent);

在Other_Activity：

In Other_Activity :

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  Bundle extras = getIntent().getExtras();
  if (extras != null) {
   String datas= extras.getString("EXTRA_ID");
   if (datas!= null) {
        // do stuff
   }        
}
