In order to update a UI control (TextView) periodically, I create a Runnable
which updates the control but instead of creating an explicit Handler and
posting the runnable to that, I post the runnable directly to the control. I
find the later to be simple but most readings on the web seem to be using an
explicit Handler object. Any reasons, I should be careful about?
Runnable runnable = new Runnable() {
@Override
public void run() {
textview.setText(String.valueOf(counter));
textview.postDelayed(runnable, 20000);
}
};
@Override
public void onResume() {
super.onResume();
textview.post(runnable);
}
@Override
public void onPause() {
super.onPause();
textview.removeCallbacks(runnable);
}
