Android 使用 bundle 将数据从一个 Activity 发送到另一个 Activity

Question

我必须 Activity AnswerQuestion.java 和 SendAnswerToServer.java，我想将数据从第一个 Activity 发送到另一个 Activity

在 AnswerQuestion Activity 上我这样写:

Bundle basket = new Bundle();
basket.putString("time", timeToAnswer+"");
Intent goToSendServer = new Intent(AnswerQuestion.this, SendAnswerToServer.class);
goToSendServer.putExtras(basket);
startActivity(goToSendServer);

我的问题是我要在 SendAnswerToServer Activity 上写些什么，谢谢

Answer 1

在 SendAnswerToServer Activity 中:

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    Bundle bundle = this.getIntent().getExtras();  

    if(bundle !=null)
    {
            //ObtainBundleData in the object 
      String strdata = bundle.getString("time"); 
       //Do something here if data  received
     }
     else
     {
       //Do something here if data not received
     }
