Android 开发教程

-----------------------------------Android 编 程 基 础
4 新 建 一 个 myImageAdapter 类 --Gallery 的 适 配 器 , 它 继 承 于 BaseAdapter 类 .
package zyf.Ex_Ctrl_10ME;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
public class myImageAdapter extends BaseAdapter {
@Override
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
@Override
public Object getItem(int
position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int
position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int
int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
return null;
}
}
5 修 改 mainActivity.java, 添 加 Gallery 相 关 操 作
package zyf.Ex_Ctrl_10ME;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Gallery;
import android.widget.ImageView;
import android.widget.Toast;
public class Ex_Ctrl_10ME extends Activity {
/** Called when the activity is first created. */
/* 定 义 要 使 用 的 对 象 */
private Gallery gallery;
private ImageView imageview;
