Animation Translate using LayoutParams

Question

Basically i want to create translate animation but for some reason i cannot use TranslateAnimation class. Anyway this is my code

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"      
  android:id="@+id/layout"   
  android:orientation="vertical"     
  android:layout_width="fill_parent"   
  android:layout_height="fill_parent">   
  <ImageView
    android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_launcher"/> 
</RelativeLayout>

MainActivity.java

package com.test2;

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener;
import android.widget.RelativeLayout; 
import android.widget.RelativeLayout.LayoutParams; 
import android.widget.ImageView;

public class MainActivity extends Activity 
{   

  private RelativeLayout layout;   
  private ImageView image;   
  private LayoutParams imageParams;

  @Override   
  public void onCreate(Bundle savedInstanceState)   
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    layout = (RelativeLayout) findViewById(R.id.layout);
    image = (ImageView) findViewById(R.id.image);
    imageParams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    image.setLayoutParams(imageParams);
    layout.setOnClickListener(new ClickHandler());   
  }

  class ClickHandler implements OnClickListener   
  {
    public void onClick(View view)
    {
      // This is the animation part
      for (int i = 0; i < 100; i++)
      {
        imageParams.leftMargin = i;
        image.setLayoutParams(imageParams);
        // repaint() in java
        try
        {
          Thread.sleep(100);
        }
        catch (Exception e)
        {

        }
      }
    }   
  }
}

My problem is I need to do repaint() before using Thread.sleep otherwise the animation will not work and the object will just move to its final position. I've tried invalidate, requestLayout, requestDrawableState but none works. Any suggestion?

EDIT:

              {
                imageParams.leftMargin = i;
                image.setLayoutParams(imageParams);
                i++;
                if (i == 15)
                {
                  timer.cancel();
                  timer.purge();
                }
              }
            }, 0, 100
          );
        }

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
</RelativeLayout>


package com.example.example;

import java.util.Timer;
import java.util.TimerTask;

import android.os.Bundle;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.app.Activity;

public class MainActivity extends Activity {


    ImageView imageView;
    RelativeLayout.LayoutParams params;
    int i=0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        imageView=new ImageView(this);
        RelativeLayout main=(RelativeLayout)findViewById(R.id.main);

        params=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
        imageView.setBackgroundResource(R.drawable.ic_launcher);

Answer 2

you can use timer task instead of sleep
Like:-
int i=0;
Timer timer=new Timer();
        timer.scheduleAtFixedRate(new TimerTask() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
 imageParams.leftMargin = i;
        image.setLayoutParams(imageParams);
                i++;
                if(i==100){
                    timer.cancel();
                    timer.purge();
                }
            }
        }, 0, 1000);
