我能够将android-5.0.1_r1的源代码放到我的工作目录中.但是,我在模拟器上构建和运行代码时遇到了麻烦,因为午餐命令给我带来了麻烦.

我正在尝试使用本地广播接收器在 editText 字段（位于片段内）内显示扫描的条形码。

这是我的代码：

MainActivity.java 中的 OnActivityResult

public void onActivityResult(int requestCode, int resultCode, Intent intent){
    Log.d("onActivityResultCalled", "yes");
    if(requestCode == IntentIntegrator.REQUEST_CODE){
        if (resultCode == RESULT_OK){
            String contents = intent.getStringExtra("SCAN_RESULT");
            String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
            Log.d("content", contents);
            Log.d("format", format);
            Log.d("sender", "Broadcasting message");
            Intent scanIntent = new Intent("scanEvent");
            scanIntent.putExtra("isbn",contents);
            LocalBroadcastManager.getInstance(this).sendBroadcast(scanIntent);



        }else if(resultCode == RESULT_CANCELED){
            Log.e("MainActivity","Scan cancelled?");
        }
    }
}

接收广播并显示 isbn 的代码：

@Override
public void onResume()
{
    super.onResume();
    LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mMessageReceiver,
            new IntentFilter("scanEvent"));
}

// Our handler for received Intents. This will be called whenever an …
