无法getIntExtra（）时的onActivityResult [英] Can not getIntExtra() at onActivityResult

问题描述

我有一个问题通过意图从一个活动到另一个发送和接收int型;

I got a problem with sending and receiving int types from one activity to another via Intent;

我正在与的onActivityResult（）函数被放置在接收活动发送。

I'm sending it with onActivityResult() function which is placed at the receiving activity.

的的code：的

发送活动：的

The Sending Activity:

Intent ba=new Intent();

MyPoints = fgv.getPoints();

int MP=(int)MyPoints;
Log.i("Problem","MyPoints MP = "+MP);

ba.putExtra("FocusScore",MP);
Log.i("Problem","MyPoints = "+MP);

setResult(RESULT_OK,ba);
finish();

在接收活动：

//在onClick的以移动其他类

//At the onClick in order to move the the other class

意图goFocus =新意图（Games.this，FocusGame.class）;

Intent goFocus =new Intent(Games.this,FocusGame.class);

startActivityForResult（goFocus，1）;

startActivityForResult(goFocus,1);

//在函数的onActivityResult

//At the onActivityResult function

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if(resultCode==RESULT_OK)
        {   

          switch (requestCode) {

             case 1: {
             //Coming back from Focus-Game
             //Problem:!!

              int sss= getIntent().getIntExtra("FocusScore", -1); 
              Log.i("Problem","sss = "+sss);

                 }
             break;

             default :
             break;

            }

}

在code的结果给出一个日志，其中SSS = -1。这意味着

The result of the code is given a log where sss=-1. Which means that

getIntent（）getIntExtra（）;

getIntent().getIntExtra();

总是空。

而MP的登录工作正常。

And the Log of the MP is working fine.

希望你能帮助我在这里。

Hope you could help me over here.

推荐答案

使用数据的价值不是 getIntent（）

if (data != null) {
    //int sss= getIntent().getIntExtra("FocusScore", -1); 
    Bundle extras = data.getExtras();
    int sss =  extras.getInt("FocusScore");
}

或只是

if (data != null) {
    //int sss= getIntent().getIntExtra("FocusScore", -1);     
    int sss= data.getIntExtra("FocusScore", -1); 
}
