GestureListener on gridview

[chetan deol]

Does any one has the code of GestureListener on gridview items .because i should perform left ,right flig on gridview and long press and touch and click on gridview items. .while long press on the items in grid view i should get the x,y coordinate values,but
gridview.setOnItemLongClickListener(new OnItemLongClickListener()
{

@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {}

this long clickable does not have parameters of motionevent...

                        //on longpress
			gridview.setOnItemLongClickListener(new OnItemLongClickListener()
			{

				@Override
				public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
						int arg2, long arg3) {
					// TODO Auto-generated method stub
					arg1.bringToFront();
					Toast.makeText(DockitControllerActivity.this, "" + "long press", Toast.LENGTH_SHORT)
					.show();	
					omniBox.setBackgroundResource(R.drawable.omni_selected);
					eye.setImageResource(R.drawable.dustbin_hgltd);
					
					return false;
				}});
			
			
			
			
			//onTouch
			gridview.setOnTouchListener(new OnTouchListener() {
				
				@Override
				public boolean onTouch(View v, MotionEvent event) {
//					// TODO Auto-generated method stub
					//ImageAdapter im =new ImageAdapter();
				
					int x=(int)event.getX();
					int y=(int)event.getY();
					Log.d("x-value",""+x);
					Log.d("Y-value",""+y);
					//image = new ImageView(DockitControllerActivity.this);
					//image.setImageBitmap(im.imageView.getDrawingCache());
					//image.setImageResource(R.drawable.a_1);
					//Layout.addView(image, params);
//					Toast.makeText(DockitControllerActivity.this,""+x+" "+y, Toast.LENGTH_SHORT);
					if (event.getAction() == MotionEvent.ACTION_DOWN) {
						
						image = new ImageView(DockitControllerActivity.this);
						//Bitmap bp=btn.getDrawingCache();
						//Log.d("bitmap in dragme",""+bp);
						image.setImageResource(R.drawable.a_1);
						Layout.addView(image, params);
						System.out.println("start Dragging");
					}
					if (event.getAction() == MotionEvent.ACTION_UP) {
						//status = STOP_DRAGGING;
						Log.i("Drag", "Stopped Dragging");
					} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
						//if (status == START_DRAGGING) {
							System.out.println("Dragging");
							image.setPadding((int) event.getRawX(), (int) event.getRawY(), 0, 0);
							image.invalidate();
						//}
					}
				
				return false;
				}
			});
			
			
			
			//OnItemClickListener for GridView
			gridview.setOnItemClickListener(new OnItemClickListener() {
				public void onItemClick(AdapterView<?> parent, View v,
					int position, long id) {
					
					previewDialog(position);
					
				}
							});

We must do 2 steps to work the long press event:

1. set item's long click listener:

  mGrid.setOnItemLongClickListener(listener);

private OnItemLongClickListener listener = new OnItemLongClickListener() {

		@Override
		public boolean onItemLongClick(AdapterView<?> parent, View view,
				int position, long id) {
			Log.d(TAG, "OnItemLongClickListener");
			choicedPosition = position;
			showDialog(DIALOG_DELETE_ONE_WMICON);
			return true;
		}
	};
  

2. in our Adapter's overided function "getView", we shuold set every item be LongClickable.

  public View getView(int position, View convertView, ViewGroup parent) {
			ImageView imgV = new ImageView(IconWatermarkChoice.this);
			File file = fileList.get(position);
			Bitmap oriBitmap = FileOperateUtil.loadImage(file);
			//
			setImgOnclickLstnr(imgV, file);
			 
			imgV.setImageBitmap(Bitmap.createScaledBitmap(oriBitmap, 60, 60,
					true));
			imgV.setLongClickable(true);
			return imgV;
		}
