Dynamically adding grid items in grid view

How can I dynamically add grid items in grid view? Currently, I have an adapter containing my images. I want to get my images from an URL and dynamically add them to my grid view.

Create custom adapter for grid view. And set that custom adapter for gird view. Here is the xml code for grid item.

    <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:id="@+id/GridItem"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content">

       <imageview android:id="@+id/grid_item_image"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content">
       </imageview>
    </linearlayout>

and here is xml for main layout.

    <gridview xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/GridView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    </gridview>

and here is custom adapter class which extends from BaseAdapter

    public class ImageAdapter extends BaseAdapter
    {
    Context context;

  public ImageAdapter(Context context)
  {
     context = context;
  }

  @Override
  public int getCount() 
  {
     //return numbers of element u want on the grid
     return 9;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) 
  {
     View v = convertView;

     if ( convertView == null )
     {
        //here we inflat the layout
        LayoutInflater li = getLayoutInflater();
        v = li.inflate(R.layout.grid_item, null);

        //here add the image      
        ImageView iv = (ImageView)v.findViewById(R.id.grid_item_image);
        iv.setImageResource(R.drawable.icon);
     }

     return v;
  }

  @Override
  public Object getItem(int arg0) {
     // TODO Auto-generated method stub
     return null;
  }

  @Override
  public long getItemId(int arg0) {
     // TODO Auto-generated method stub
     return 0;
  }
  }

Hope this can help u.
