Question

I have a question that I have a custom grid view in which two images one is the background image and second is the check mark image, when I clicked on one Item of grid view

Well, there is one simple way to do this. You can keep reference of previously selected item. e.g. you make a variable at class level, where you are using the adapter. Then in your onClick listener, you un-select that image and set that variable with the current view(current image). e.g.

ImageView iv_selected = null;

// ..........

@Override
public void onClick(View view) 
{
     Log.i("Clicked", "Tag###########");
     if(iv_selected != null)
     {
          // unselect the image here
     }
     // set this variable again e.g.
     iv_selected = (ImageView)view;


     //img_select.setVisibility(View.INVISIBLE);
     img_select.setFocusable(true);
     img_select.setEnabled(true);
     if(checked==0)
     {

          img_select.setBackgroundResource(R.drawable.selectimage);
          GreetingTextContainer greet = GreetingTextContainer.getSingletonObject();
          greet.setPosition(position);
          checked =1;
     }
     else
     {
          img_select.setBackgroundResource(0);
          checked=0;
     }
}

in this you'll always have the refernce of the single selected ImageView. So, you can uncheck it when you select something else. I hope you got the idea.
