Question

我是android的初学者。我在我的应用程序中集成了qr扫描仪。问题是我在两个片段中添加了qr扫描仪按钮...为了接收结果我在activityResult方法上添加了...在我的主动作中..是任何其他方法接收结果在android而不是OnactivityResult方法..如果不是他们我应该添加多个onActivityResult方法在我的Mainactivty ..can anyOne帮助我..

below is the my code for onActivityresult
     @Override
     public void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult scanResult =IntentIntegrator.parseActivityResult(requestCode, resultCode, 
                data);
    if (scanResult != null) {

        if (scanResult.getContents() == null) {

            Log.d("ScanFragment", "Cancelled scan");
            Toast.makeText(this, "Cancelled", Toast.LENGTH_SHORT).show();
        } else {

            Toast.makeText(this, " " + scanResult.getContents(), Toast.LENGTH_SHORT).show();


        }

    } else {
        //result fragment
        super.onActivityResult(requestCode, resultCode, data);
    }
    // }

}

Answer 1

static final int FRAGMENT_ONE_REQUEST = 1;  // The request code
static final int FRAGMENT_TWO_REQUEST = 2;  // The request code

然后从片段1中使用它

 startActivityForResult(intent, FRAGMENT_ONE_REQUEST);

然后从片段二中使用它

startActivityForResult(intent, FRAGMENT_TWO_REQUEST);

每个片段中的

@Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode == Activity.RESULT_OK) {
       //some code
         if (requestCode == FRAGMENT_ONE_REQUEST) {
       }
    }
}

在android中接收结果
