Printing integer values in a textview and thread sleep time

Question

How do I print integer values in a textview and also when I increasing the sleep time in the thread its not working correctly in android.

package com.example.chaljayar;   
import java.util.concurrent.Delayed;
import android.os.Bundle;   
import android.app.Activity;   
import android.view.Menu;  
import android.widget.TextView;

public class MainActivity extends Activity implements Runnable 

   {

       TextView Tv;
       int num = 0, i = 0;
       String con = "";

@Override
protected void onCreate(Bundle savedInstanceState)
  {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Tv = (TextView)findViewById(R.id.Text);
    Thread test = new Thread(this);
    test.start();
}
    @Override
    public void run() 
    {
        // TODO Auto-generated method stub
        while(i <= 100)
        {
            try{            
                    con += Integer.toString(i);
                    Tv.setText(con);
                    Thread.sleep(1000);
            } catch (Exception e)
            {
                // TODO: handle exception
                e.printStackTrace();
            }
            i++;
        }
    }

}

What exactly is not working? What does it do and what do you expect it to do? — Tim, Apr 11 '13 at 20:42

Try this To Thread alone and the other out of (try/catch) :

    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {

        e.printStackTrace();
    }

when use thread.sleep you can use it in if statement and in any where in your program but not in the loop !! you are call the sleep more than once ,,, sure that's could be crashed your app !! how you can sleep your app if it slept :\ – Oubaida AlQuraan Apr 13 '13 at 15:08
