这个类必须是公共类

代码

public class HigherPriorityReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "HigherPriorityReceiver", 0).show();
        setResultCode(1985);
        setResultData("DOB");
        //abortBroadcast();
    }
}
