Android Bundle的使用

发送数据：

Bundle bundle = new Bundle();

bundle.putString("sex" , "男人");

bundle.putDouble("height" , 40,38);

Intent intent = new Intent();

intent.putExtras(bundle);

intent.setClass(ThisOne.this , ThatOne.class);

startActivity(intent);

接收数据：

Bundle bundle = this.getIntent().getExtras();

String sex = bundle.getString("sex");

double height = bundle.getDouble("height");

====================================

在Message中使用Bundle传递数据

Message msg = myHandler.obtainMessage();

Bundle b = new Bundle();

b.putInt("age" , 20);

b.putString("name" , "Jon");

msg.setData(b);

msg.sendToTarget();

class MyHandler extends Handler{

   public void handleMessage(Message msg){

      Bundle b = msg.getData();

      int age = b.getInt("age");

      String name = b.getString("name");

  }

}
