Thanks a lot rich .. i got worked this way

import android.graphics.Color;

import android.os.Bundle;

import android.view.GestureDetector;

import android.view.MotionEvent;

import android.view.GestureDetector.OnGestureListener;

import android.widget.LinearLayout;

import android.widget.TextView;

public class GestureSampleThreeExample extends Activity implements OnGestureListener {

private LinearLayout main;

   private TextView viewA;

   private GestureDetector gestureScanner;

   @Override

   public void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       gestureScanner = new GestureDetector(this);

       main = new LinearLayout(this);

       main.setBackgroundColor(Color.GRAY);

       main.setLayoutParams(new LinearLayout.LayoutParams(320,480));

       viewA = new TextView(this);

       viewA.setBackgroundColor(Color.YELLOW);

       viewA.setTextColor(Color.BLACK);

       viewA.setTextSize(16);

       viewA.setLayoutParams(new LinearLayout.LayoutParams(320,80));

   }

   @Override

   public boolean onTouchEvent(MotionEvent me) {

       return gestureScanner.onTouchEvent(me);

   }

   public boolean onDown(MotionEvent e) {

       viewA.setText("-" + "DOWN" + "-");

       return true;

   }

   public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {

       viewA.setText("-" + "FLING" + "-");

       return true;

   }

   public void onLongPress(MotionEvent e) {

       viewA.setText("-" + "LONG PRESS" + "-");

   }

   public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {

       viewA.setText("-" + "SCROLL" + "-");

       return true;

   }

   public void onShowPress(MotionEvent e) {

       viewA.setText("-" + "SHOW PRESS" + "-");

See nrmally when we have a button in a page in the onClick(View  v ){
if(btn1==v)
{

startActivity(new
Intent(FirstScreenActivity.this,SecondScreenActivity.class));

}

}

 

If that is the way you are doing it then I would (as others have) recommend reading up on how to listen and respond to click events. I see absolutely no reason to use an if/else statement when the listener is tied directly to the button.

Also you can make the ENTIRE view clickable: http://developer.android.com/reference/android/view/View.OnClickListener.html
