致电显示（）方法为吐司。

I have a broadcast receiver and I am trying to show a toast message from it, is this possible ? This code doesn't show the toast but it print the log message in the logcat. Is there some idiotic thing I am doing or what is my problem ?

@Override
public void onReceive(Context context, Intent intent) {
    Log.v("log", "this is shown");
    Toast.makeText(context, "this is not shown"     , Toast.LENGTH_LONG);
}

Call the show() method for the Toast.
