Re: [android-developers] Re: update TextView inside a TimerTask

Hi
thanks
i wonder if you help me with an example!
i implemented timer like this:

Timer t = new Timer();

TimerTask tt = new TimerTask() {
     @Override
     public void run() {
     }
 };
t.scheduleAtFixedRate(tt, 100, 1000);

my texview is this:

TextView tv = (TextView)findViewById(R.id.TextView06);
tv.setText( String.valueOf(myval));

If I'm not mistaken, any code inside a TimerTask is running on a different thread. This means that it won't have access to the main UI thread. So if you put some code in there to update your Textview, you will probably end up with an exception or error saying that it cannot access the main ui thread. To fix this, you will need to create a message handler (Handler) so that you can send "messages" to your main ui thread telling it to update the Textview accordingly.
