Hi,
I'm not sure which thread timers fire in, but have you tried calling the
setText explicitly from the UI thread?
final String timeSinceUpdate = tracker.getUpdateAge();
runOnUiThread(new Runnable()
{
public void run()
{
mMyTextView .setText("Current location (" + timeSinceUpdate +
")";
}
}
Peter.

Subject: [android-developers] TextView.setText doesn't update
I have a Timer set up to update a TextView field once every second.
Thing is, I can't see any changes on screen!
Debugging shows...
setText inside the timer function *is* being called.
getText called on the text view returns the *correct* (new) text that
just isn't displayed!
I've tried TextView.postInvalidate() to no effect.
Code below.
Anyone seen this before?
Thanks.

IN MyActivity.onCreate:
mMyTextView = (TextView)this.findViewById
(R.id.txtcurloctitle);
FROM MyTimerTask.Run
String timeSinceUpdate = tracker.getUpdateAge();
mMyTextView .setText("Current location (" + timeSinceUpdate +
"):");
IN MyActivity.onOptionsItemSelected:
AlertDialog.Builder msg = new AlertDialog.Builder(this);
msg.setTitle("Debug");
msg.setMessage(mMyTextView.getText());
msg.setPositiveButton("OK", null);
msg.show();
