XML : How Can I use Same Adapter of a GridView on Different activities

Let say I have two Activities, Activity A and Activity B.

Activity A displays a list of images using the Adapter Z.

When user clicks on any image in Activity A, they will be taken to Activity B to show the full image. I'm passing image path and grid position to Activity using Intent.

Now in Activity B, I place a delete button which should delete the imagepath from the gridview adapter.

Problem is: How can I access the Activity A adapter in activity B to call remove(position) method in my adapter.

So I can call notifyDataSetChanged in onResume of Activity A to update the gridview images.

Activity A

  MyGridView = (GridView) findViewById(R.id.gridview);  adapter = new MyAdapter(this);  MyGridView .setAdapter(adapter );        Intent fullImageActivity = new Intent(getApplicationContext(), ActivityB.class);      fullImageActivity.putExtra("position", position);      fullImageActivity.putExtra("path", mediaPath);      startActivity(fullImageActivity);    

Activity B

  Intent i = getIntent();  // I'm getting position and path from setOnItemClickListener  position = i.getExtras().getInt("position");  path = i.getExtras().getString("path");    // I want to remove path from my adapter after clicking delete button in Activity B    

Adapter

  public ArrayList<String> images;        public void remove(int position){              images.remove(position);          }
