Android toast message from a separate thread class

Question

I am confused about how to use Toast to print out messages. I need to use it to print out messages that come from the thread's while loop. My thread which renders graphics are on a different class than my activity. I mean, they are not implemented in the same file. Is there a way to do this?

Answer 1

You can use runOnUiThread:

myActivity.runOnUiThread(new Runnable() {

 public void run() {
    Toast.makeText(context, text, duration).show();
 }

});
