جابجایی بین اکتیویتی ها با لمس صفحه

اگر عکس نباشه چیکار کنم. اکتیویتی باشه.

این کد رو هیچ جا گیر نمیاری  من برات میذارم  (:

اینا رو تو بالای oncreate معرفی کن       

 	  private GestureDetector gDetector;
		private static final int SWIPE_MIN_DISTANCE = 120;
		private static final int SWIPE_MAX_OFF_PATH = 250;
		private static final int SWIPE_THRESHOLD_VELOCITY = 200;

اینا هم تو خود oncreate 

 Context context = this;
		gDetector = new GestureDetector(context, this);
		Log.d(Thread.currentThread().getStackTrace()[2].getClassName()
				.substring(
						Thread.currentThread().getStackTrace()[2]
								.getClassName().lastIndexOf(".") + 1)
				+ "."
				+ Thread.currentThread().getStackTrace()[2].getMethodName()
				+ "():"
				+ Thread.currentThread().getStackTrace()[2].getLineNumber(),
				"it worked");
	}
 
	public boolean onDown(MotionEvent arg0) {
		// TODO Auto-generated method stub
		return false;
	}
 
	@Override
	public boolean dispatchTouchEvent(MotionEvent ev) {
		super.dispatchTouchEvent(ev);
		return gDetector.onTouchEvent(ev);
	}
 
	public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
			float velocityY) {
 
		// Check movement along the Y-axis. If it exceeds
		// SWIPE_MAX_OFF_PATH,
		// then dismiss the swipe.
		if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
			return false;
 
		// Swipe from right to left.
		// The swipe needs to exceed a certain distance (SWIPE_MIN_DISTANCE)
		// and a certain velocity (SWIPE_THRESHOLD_VELOCITY).
		if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
				&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
			// next();
			Log.e(Thread.currentThread().getStackTrace()[2].getClassName()
					.substring(
							Thread.currentThread().getStackTrace()[2]
									.getClassName().lastIndexOf(".") + 1)
					+ "."
					+ Thread.currentThread().getStackTrace()[2].getMethodName()
					+ "():"
					+ Thread.currentThread().getStackTrace()[2].getLineNumber(),
					"Swipe from right to left");
			

			 Intent intent = new Intent(this, vob16_32.class);
				                   startActivity(intent);
			            finish();
			
			return true;
		}

		if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
				&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
			// previous();
			Log.e(Thread.currentThread().getStackTrace()[2].getClassName()
					.substring(
							Thread.currentThread().getStackTrace()[2]

					+ "."
					+ Thread.currentThread().getStackTrace()[2].getMethodName()

					"Swipe from left to right");
			

			 Intent intent = new Intent(this, vob16_30.class);
				                   startActivity(intent);
			            finish();

			return true;
		}
 
		return false;
	}
 
	public void onLongPress(MotionEvent arg0) {
		// TODO Auto-generated method stub
 
	}
 
	public boolean onScroll(MotionEvent arg0, MotionEvent arg1, float arg2,

	}

	}

	}

	public void onGestureCancelled(GestureOverlayView overlay,

	}

	public void onGestureEnded(GestureOverlayView overlay, MotionEvent event) {
		// TODO Auto-generated method stub
		
	}

	public void onGestureStarted(GestureOverlayView overlay,
			MotionEvent event) {
		// TODO Auto-generated method stub
		
}
}

 برای رفتن به سمت راست این قسمت رو تغییر بده

  Intent intent = new Intent(this, vob16_32.class);//اکتیویتی دلخواه
				                   startActivity(intent);
			            finish();

برای سمت چپ اینو 

 Intent intent = new Intent(this, vob16_30.class);//اکتیوتی دلخواه
				                   startActivity(intent);
			            finish();
