}
//@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView view = (ImageView)convertView;
if(view == null)
{
view = new ImageView(ctx);
}
view.setLayoutParams(new GridView.LayoutParams(90, 90));
view.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
view.setPadding(1, 1, 1, 1);
view.setImageResource(images[position]);
return view;
}
}
4. 修改 Activity 所对应的代码，使之如下：
package com.pat.gui;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.GridView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class ControlGridView extends Activity
implements
OnItemClickListener
{
private GridView gridview;
private ImageAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gridview = (GridView)findViewById(R.id.gridview);
adapter = new ImageAdapter(this);
gridview.setAdapter(adapter);
gridview.setOnItemClickListener(this);
}
//@Override
public void onItemClick(AdapterView< > parent, View view, int position, long id)
{
Toast.makeText(this, "" + position, Toast.LENGTH_SHORT).show();
}
}
输出结果：
