Question

I have implemented a thread in android which refresh the fragment (some text list ) for every 1 second .

its giving the runtime error while calling the fragment method at thread ,. here is my code

public class RunThreadExtended extends Activity implements Runnable
{
public void run() {

 while(true)
 {  try {
    Thread.sleep(1000);
    AndroidListFragmentActivity.strup++;
    MyListFragment1 fragmentB = (MyListFragment1)getFragmentManager().findFragmentById(R.id.fragment1);
    fragmentB.updatefrag();
} catch (InterruptedException e) {
    e.printStackTrace();
}
  }}}

If I call the fragment method from Mainactivity everything works from , since I need to refresh the thread for every 5 seconds in the backgroud I have implemented like this , but its not working ..pls suggest solution …

I think you have to do the refreshing in

yourActivity.runOnUiThread(new Runnable() {
public void run()   { /* here */ });

Or via a Handler, or via a post() or in an AsyncTask‘s onProgress()
