Android Loop Update Textview

I am trying to create a loop that will update a TextView. The idea is to create some sort of progress indicator, that will increment the loading precentge. This is what I have trie

Solution 1:

Your Runnable blocks the UI thread when doing Thread.sleep. Instead of sleeping, you should post a new Runnable again. Try with something like this:

finalHandlerhandler=newHandler();
handler.post( newRunnable(){ 
    privateintk=0;

    publicvoidrun() {
        finalTextViewprogess= (TextView)findViewById(R.id.progress);
        progess.setText(String.valueOf(k) + "%");

        k++;
        if( k <= 100 )
        {
            // Here `this` refers to the anonymous `Runnable`
            handler.postDelayed(this, 15);
        }
    }
});

That will give the UI thread a chance to run between each call, letting it do its stuff like handling input and drawing stuff on the screen.

Solution 2:

You use background thread and UI Thread.

public class testAsync extends AsyncTask<Void, Integer, Voi>{

TextView progress; // You will set TextView referans

protected void doInBackground(){

 for(int k=1 ; k<=100; k++)

  {

    try {
    Thread.sleep(1000);
    publishProgress(k); 
   } catch(InterruptedException e) {}
   }
 }
protected void onProgressUpdate(Integer.. values)
{
progress.setText(values[0]+");
}

}
