title: Remove item from GridView
body: <p>I am very new to android development and I feel like this is very simple, yet, I haven't managed to find anyone on google with the same problem. 
  I have a Gridview that is filled with a TextView (which has an image on top) and an ImageButton (to delete the current item). What I want to do is to remove the item of which I click the ImageButton.</p>
  
  <p>Here is my Main :</p>
  
  <pre><code>public class ActivityMain extends Activity
  {
  GridView gridview;
  public GridAdapter mainActivityAdapter;
  public ArrayList&lt;String&gt; listService = new ArrayList&lt;String&gt;();
  
  @Override
  protected void onCreate(Bundle savedInstanceState)
  {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      listService.add("Market");
      listService.add("Recherche");
      listService.add("Quiz");
  
      gridview = (GridView) findViewById(R.id.mainActivity_grid);
      mainActivityAdapter = new GridAdapter(this.getApplicationContext(), listService);
  
      gridview.setAdapter(mainActivityAdapter);
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>And here is my Adapter :</p>
  
  <pre><code>    public class GridAdapter extends BaseAdapter
      {
      Context context;
      ArrayList&lt;String&gt; list = new ArrayList&lt;String&gt;();
      GridAdapter adapter = this;
  
      public GridAdapter(Context context, ArrayList&lt;String&gt; list)
      {
          this.context = context;
          this.list = list;
      }
  
      @Override
      public int getCount()
      {
          return list.size();
      }
  
      @Override
      public Object getItem(int arg0)
      {
          return null;
      }
  
      @Override
      public long getItemId(int arg0)
      {
          return 0;
      }
  
      @Override
      public View getView(final int position, View convertView, ViewGroup parent)
      {
          ViewHolder holder;
      if(convertView==null)
      {
          convertView = LayoutInflater.from(context).inflate(R.layout.item_gridmain, null);
  
          holder = new ViewHolder();
          holder.textView = (TextView) convertView.findViewById(R.id.gridMain_text);
          holder.close = (ImageButton) convertView.findViewById(R.id.mainActivity_delete);
  
          convertView.setTag(holder);
      }
  
      else{
          holder = (ViewHolder) convertView.getTag();
      }
  
  // Doing stuff on views
  
          holder.close.setOnClickListener(new View.OnClickListener()
          {
              public void onClick(View arg1)
              {
                  // list.remove(position);
                  list.remove(position);              
                  adapter.notifyDataSetChanged();
              }
          });
          return convertView;
  
      }
  
  public static class ViewHolder
  {
      TextView textView;
      ImageButton close;
  }
  
  }
  </code></pre>
  
  <p>The thing is, when I click on one ImageButton, it's always the last item that has been added that is being removed and I can't figure out why or how to fix this.</p>
  
  <p>Thank you.</p>
  
  <p>==================
  EDIT :</p>
  
  <p>Here is my activity_main.xml :</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/main_layout"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"

  android:orientation="vertical" &gt;
  
  &lt;GridView
      android:id="@+id/mainActivity_grid"

      android:layout_marginLeft="5sp"
      android:layout_marginRight="5sp"
      android:layout_marginTop="5sp"

      android:verticalSpacing="10dp" /&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>And my item_gridmain.xml :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

      android:layout_gravity="center"
      android:textAlignment="center"
      android:textColor="@android:color/holo_blue_dark"
      /&gt;
  
   &lt;ImageButton
      android:id="@+id/mainActivity_delete"
      style="?android:attr/borderlessButtonStyle"
      android:layout_width="wrap_content"
