我的代码

**07-07 15:24:25.021: WARN/ActivityManager(57): Activity is launching as a new task, so cancelling activity result.**
07-07 15:24:25.681: WARN/ActivityManager(57): Activity pause timeout for HistoryRecord{43cccce8 com.tcs.QuickNotes/.QuickNotesHome}

07-07 15:24:27.420: INFO/resultCode(1370): **resultCode0**

它没有输入上述代码。 结果代码始终为0

从中返回控件的代码：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.i("AudioPathIn onActivityResult"," onActivityResult"+audioFilePath.getText().toString());
        Log.i("requestCode ","requestCode"+requestCode);
        Log.i("resultCode ","resultCode"+resultCode);
        if(requestCode == 1)
        {
            if(resultCode == RESULT_OK)
            {
                Audioflag=1;
                audioFilePath.setVisibility(View.VISIBLE);

                String defaultToneStatus = data.getStringExtra("DefaultTone");
                if(defaultToneStatus.equals("false"))
                {
                    audioFilePath.setText(AudioRecorder.getFilePath());
                }
                else
                {
                    defaultAudioToneFlag = 1;
                    audioFilePath.setText("-");
                }

            }else
            {
                Audioflag=0;
            }
        }

    }

正如奔腾10所注意到的，您正在调用

setResult（RESULT\u取消）输入
onCreate（）。
调用setResult（）调用activityResult

方法

取消的结果_的值为

0x00000000

。

所以只需从onCreate方法中删除调用setResult

为什么要在onCreate中设置结果<代码>设置结果（结果被取消）
