Android “Only the original thread that created a view hierarchy can touch its views.”

Question

I\'ve built a simple music player in Android. The view for each song contains a SeekBar, implemented like this:

public class Song extends Activity implement         


        

Answer 1

I had a similar issue, and my solution is ugly, but it works:

void showCode() {
    hideRegisterMessage(); // Hides view 
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            showRegisterMessage(); // Shows view
        }
    }, 3000); // After 3 seconds
}
