title: Android Gridview and Button OnItemclick
body: <p>Here is my buttonAdapter class that i think is accurate:</p>
  
  <pre><code>package com.example.test;
  
  import android.content.Context; 
  import android.graphics.Color; 
  import android.view.View; 
  import android.view.ViewGroup;
  import android.widget.BaseAdapter;
  import android.widget.Button; 
  import android.widget.GridView;
  
  public class ButtonAdapter extends BaseAdapter { 
      private Context mContext; 
      public String [] fName = { "File 1", "File 2", "Roflcopters"};
  
      // Gets the context so it can be used later 
      public ButtonAdapter(Context c) { mContext = c; }
  
      // Total number of things contained within the adapter 
      public int getCount () { return 8; }
  
      // Require for structure, not really used in my code. 
      public Object getItem (int position) {  return null; }
  
      // Require for structure, not really used in my code. Can be used to get the id of an item in the adapter for manual control. 
      public long getItemId (int position) { return position; }
  
      public View getView (int position, View convertView, ViewGroup parent){     
          Button btn;         
          if (convertView == null) {      // if it's not recycled, initialize some attributes      
              btn = new Button (mContext);
              btn.setLayoutParams (new GridView.LayoutParams (190, 190));
              btn.setPadding (1, 1, 1, 1);    
          } else {        
              btn = (Button) convertView;
          }       
        // btn.setText(filesnames[position]);   
        // filenames is an array of strings    
        //btn.setTextColor (Color.WHITE);
        //btn.setBackgroundResource (R.drawable.sample_2);  
        //btn.setBackgroundColor (Color.BLACK);     
        btn.setHighlightColor(Color.GREEN);    
        btn.setId (position);
  
        return btn; 
      } 
  }

  <p>Here is my home class. I can't get the onItemClick to work out. What am I doing wrong here: </p>

  <p>The onItemClick doesn't work and neither does the commented 'setOnItemClickListener' when it isn't commented out and 'onItemClick' is commented. What am I doing wrong?</p>
