Question

I’m developing an android game that uses a surface view for representing the ui graphics. I need to implement a method to start another activity if the user touches a specific area.
for this i’m passing the main (foreground) activity’s current instance to the surface view

I can handle the touch easily but cannot start the activity from received instance.

**> if i call startActivity method from the received instance of the

current activity Exceptions occurs stating that its a call from non
ui-thread**

i’m using a class extended to surface view and passed to a thread which draws on its canvas

Answer 1

Is the SurfaceView within an activity?
If so, use

runOnUiThread(new Runnable() {
  public void run() {
    //startActivity
  }
});

If you are not within an activity you really shouldn’t be starting other activities..

Also SurfaceView has a post and postDelayed methods which can be use to post Runnables on the UI thread.

  post(new Runnable() {
       public void run() {
         //startActivity
       }

   });
