You can implement a ViewHolder pattern for your adapter, and for each position, inflate your own layout.

To do that, override getView like this:

public View getView(int position, View convertView, ViewGroup parent) {            

   // A ViewHolder keeps references to children views to avoid unneccessary calls            
  // to findViewById() on each row.            
  ViewHolder holder;            
  // When convertView is not null, we can reuse it directly, there is no need            
  // to reinflate it. We only inflate a new View when the convertView supplied            
  // by ListView is null.            

  if (convertView == null) {                

    convertView = mInflater.inflate(R.layout.sample, null);   
    // Creates a ViewHolder and store references to the two children views                
    // we want to bind data to.               
   holder = new ViewHolder();                
   holder.name = (TextView) convertView.findViewById(R.id.text);               
   holder.icon = (ImageView) convertView.findViewById(R.id.icon);                
   convertView.setTag(holder);            
 } else {                
   // Get the ViewHolder back to get fast access to the TextView                
   // and the ImageView.
   holder = (ViewHolder) convertView.getTag();
 }             


  // Bind the data efficiently with the holder. 
  holder.name.setText(myElements.get(id)); 
  holder.icon.setImageBitmap( mIcon1 );

return convertView;
}

EDIT:

To change the width and height of each row, you can use something like the following, for each row on bind data section :

RelativeLayout rl = (RelativeLayout) findViewById(R.id.yourId); 
rl.getLayoutParams().height = 100;
rl.getLayoutParams().width = 100;`
