Grid Itemボタンが機能しない

Question

私はGridViewとMyAdapterというアダプタを持っています。各グリッドのボタンにはダイアログボックスが表示されません（MyAdapter.java）。ここで私は私がここで行方不明ですかわからないよ、私のコードです：

MyAdapter.java

public class MyAdapter extends BaseAdapter { 
Context context; 
ArrayList<Players> playerList; 
private static LayoutInflater inflater = null; 
Button btnRoleReveal; 

public MyAdapter(Context context, ArrayList<Players> playerList){ 
    this.context = context; 
    this.playerList = playerList; 
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 


@Override 
public int getCount() { 
    return playerList.size(); 
} 

@Override 
public Object getItem(int position) { 
    return position; 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    if (convertView == null) 
     convertView = inflater.inflate(layout_grid_item, null); 

    final Button button = (Button) convertView.findViewById(R.id.btnRoleReveal); 
    TextView idTextView = (TextView) convertView.findViewById(R.id.tv_player_id); 
    TextView nameTextView = (TextView) convertView.findViewById(R.id.tv_player_name); 
    final TextView roleTextView = (TextView) convertView.findViewById(R.id.tv_player_role); 

    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      new AlertDialog.Builder(context) 
        .setTitle("Test") 
        .setMessage("Test"); 
     } 
    }); 


    Players p = new Players(); 
    p = playerList.get(position); 
    idTextView.setText("ID: " + String.valueOf(p.getId())); 
    nameTextView.setText("Name: " + String.valueOf(p.getName())); 
    roleTextView.setText("Role: " + String.valueOf(p.getRole())); 

    return convertView; 
} 


} 

RolesFragment.java

public class RolesFragment extends Fragment implements View.OnClickListener { 

GridView gridView; 
ArrayList<Players> playersList; 
MyAdapter adapter; 
Button role; 

public RolesFragment() { 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    View view = inflater.inflate(R.layout.fragment_viewroles, container, false); 

    gridView = (GridView) view.findViewById(R.id.gv_players); 
    role = (Button) view.findViewById(R.id.btnRoleReveal); 

    DatabaseHelper databaseHelper = new DatabaseHelper(getActivity()); 
    playersList = new ArrayList<Players>(); 

    playersList = databaseHelper.getPlayers(); 
    adapter = new MyAdapter(getActivity(), playersList); 
    gridView.setAdapter(adapter); 
    return view; 
} 



@Override 
public void onClick(View v) { 

} 
}

あなたがショーを逃しています（ ）ダイアログでの呼び出し：

new AlertDialog.Builder(context) 
        .setTitle("Test") 
        .setMessage("Test") 
        .show();
