接下类首先为Id为list的ListView控件准备数据Adapter，这个Adapter非常简单就是普通的adapter继承BaseAdapter即可，代码如下：
代码
public class UserAdapater extends BaseAdapter{
@Override
public int getCount() {
return userList.size();
}
@Override
public Object getItem(int position) {
return userList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = LayoutInflater.from(getApplicationContext()).inflate(R.layout.item_user, null);
ImageView iv = (ImageView) convertView.findViewById(R.id.iconImg);
TextView tv = (TextView) convertView.findViewById(R.id.showName);
UserInfo user = userList.get(position);
try {
//设置图片显示
iv.setImageDrawable(user.getUserIcon());
//设置信息
tv.setText(user.getUserName());
} catch (Exception e) {
e.printStackTrace();
}
return convertView;
}
接下就是为这个ListView设定数据源Adapter，在账号选择窗口显示的时候进行设置，添加到id为iconSelectBtn的ImageButton的OnClickListener中代码如下：
代码
ImageButton iconSelectBtn=(ImageButton)findViewById(R.id.iconSelectBtn);
iconSelectBtn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
......
dialog.show();
UserAdapater adapater = new UserAdapater();
ListView listview=(ListView)diaView.findViewById(R.id.list);
listview.setVerticalScrollBarEnabled(false);// ListView去掉下拉条
listview.setAdapter(adapater);
listview.setOnItemClickListener(new OnItemClickListener(){
