Toast message from Broadcast Receiver

问题

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);
}

回答1:

Call the show() method for the Toast.

回答2:

you forgot to call show() on the Toast.. although i would not recommend creating toasts from BroadcastReceivers.. you might consider using Notifications

回答3:

Use this

Toast.makeText(context, "this is not shown",Toast.LENGTH_LONG).show();
