Thread: How to draw a color rectangle when I tap on android phone screen???????????????????

I am trying to display a rectangle when i tap on my android phone screen after I run the android project. This is what I have tried so far . Could anyone give an idea what to use in onTouchListener method to actually make a rectangle display when i tap ??

package example.rectangle;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Rect;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.ShapeDrawable;
import android.graphics.drawable.shapes.*;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.AttributeSet;
import android.util.Log;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
 
import java.util.Timer;
import java.util.TimerTask;
 
public class RectView extends View
{
	ShapeDrawable rect ;
	public Rect rect1 ;
	public int argbColour ;
 
    public RectView(Context context , AttributeSet attrs) 
       {
		super(context , attrs);
		initRectangle();
	}
 
    public RectView (Context context , AttributeSet attrs , int defStyle)
    {
    	super(context , attrs , defStyle);
    	initRectangle();
    }
 
     private void initRectangle()
     {
    	 rect = new ShapeDrawable(new RectShape());
    	 rect.getPaint().setColor(0xffff0000);
     }
//Draws the rectangle on canvas with a ShapeDrawable object
 
public void onDraw(Canvas canvas)
{  
   super.onDraw(canvas);
 
   rect.setBounds(250, 25,450, 600);
   rect.draw(canvas);
 
  }
 
//view.setOnTouchListener(new TouchListener());
 
public class TouchListener implements View.OnTouchListener
{
	public boolean onTouch(View v, MotionEvent e) {
		// TODO Auto-generated method stub
 
		if (v.getId()==R.id.rect )
		{
			// how to draw rectangle while the user tap on screen???????
		}
 
		return true;
	}
   }
}
 
// *******************Another activity class*****************
package example.rectangle;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
 
public class RectActivity extends Activity {
 
	private RectView rectView; 
 
	public void onCreate(Bundle savedInstanceState)
	{   super.onCreate(savedInstanceState);
	  	setContentView(R.layout.activity_rect);  
	  	rectView = (RectView)findViewById(R.id.rect);
	  	if (savedInstanceState != null)
	  	{  // activity being restored from earlier launch
 
	  	}	
	}
 
}

what if you just create a large transparent button that covers whole screen and when it is clicked then it draws rectangle.

--- Update ---

I think if you insert

mSquare = new Square();

it might work
