场景:

1. 第一个 Activity 使用 startActivityForResult 启动第二个 Activity
2. 第二个 Activity 以 startActivityForResult 开始第三个 Activity

预期结果: 第三个(最后一个) Activity 设置了一个在第二个 Activity 的 onActivityResult

当前结果: 第三个(最后一个) Activity 设置了一个结果，该结果被第一个 Activity 的onActivityResult

如何设置第三个 Activity 的结果，该结果将在第二个 Activity 的 onActivityResult 中捕获

一些代码 fragment :

第一次 Activity

public class TestProjActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.main);

    Log.i("TAAAG", "1st activity - startActivityForResult");
    Intent intent = new Intent(TestProjActivity.this, Activ2.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
    startActivityForResult(intent, 1008);
}

@Override  
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    super.onActivityResult(requestCode, resultCode, data);
    Log.i("TAAAG", "1st activity - onActivityResult");
    if (resultCode == RESULT_OK) {  
        Log.i("TAAAG", String.valueOf(requestCode));
        switch (requestCode) {  
        case 1008:
            String info = data.getExtras().getString("KEY1");
            Log.i("TAAAG", "1st activity - onActivityResult - printing result");
            Log.i("TAAAG", info);
            break;
        }
    }
}

第二个 Activity

public class Activ2 extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Log.i("TAAAG", "2nd activity - startActivityForResult");
    Intent intent = new Intent(Activ2.this, Activ3.class);

    startActivityForResult(intent, 1009);

    Intent intent2 = new Intent();
    intent2.putExtra("KEY1", "VALUE1");


    setResult(RESULT_OK, intent2);
    finish();
}

@Override  
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    super.onActivityResult(requestCode, resultCode, data);
    Log.i("TAAAG", "2nd activity - onActivityResult");
    if (resultCode == RESULT_OK) {  
        Log.i("TAAAG", String.valueOf(requestCode));
        switch (requestCode) {  
        case 1009:
            String info = data.getExtras().getString("KEY2");
            Log.i("TAAAG", "2nd activity - onActivityResult - printing result");
            Log.i("TAAAG", info);
            break;
        }
    }
}

第三个 Activity

 public class Activ3 extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Log.i("TAAAG", "3rd activity - Inserting Value and finishing");

    Intent intent = new Intent();
    intent.putExtra("KEY2", "VALUE2");

    setResult(RESULT_OK, intent);
    finish();
}

最佳答案

使用 Activity 标志将结果转发给 super Activity :

intent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);

关于android - 调用的第三个 Activity 将其结果返回给第一个 Activity 而不是将结果发送给第二个 Activity ？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9360853/
