在上一个活动的MainActivity中未调用onActivityResult [英] onActivityResult NOT called in MainActivity from previous Activity

问题描述

我知道这是一个基本问题，我在stackoverflow中看到了关于它的多个答案，但我似乎仍然停滞不前. onActivityResult只是不被调用.

I know this is a basic question and I have seen multiple answers on it in stackoverflow but I seem to be stuck still. The onActivityResult is just not being called.

这是我的代码:

1>在MainActivity中，我具有onActivityResult

1> In MainActivity I have onActivityResult

public class MainActivity extends AppCompatActivity
        implements MasterListFragment.OnImageClickListener {

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.v(LOG_TAG, "Entering onActivityResult");

    }
}

2>在我的第二项活动中，我有这个

2> In my second activity I have this

@Override
    public void onBackPressed() {

        Intent data = new Intent();
        data.putExtra("myData1", "Data 1 value");
        data.putExtra("myData2", "Data 2 value");
        setResult(Activity.RESULT_OK, data);
        finish();
    }

我做一个Log，但Log语句未显示在LOGCAT中

I do a Log and the Log statement is not displayed in the LOGCAT

推荐答案

要在OnActivityResult中返回结果，应使用startActivityForResult(Intent,REQ_CODE)方法开始第二个活动.

For getting result back in OnActivityResult you should use startActivityForResult(Intent,REQ_CODE) method for starting your second activity.
