自定义GrildView实现单选功能

首先看实现功能截图，这是一个自定义Dialog,并且里面内容由GrildView 绑定数据源，实现类似单选功能。

首先自定义Dialog，绑定数据源

自定义Dialog弹出框大小方法

最主要实现的就是点击颜色切换的功能，默认GrildView的每一项都是蓝色背景，当点击时候切换成红色。这里缓存了一个view,每次点击给这个view重新赋值，改变颜色

数据源Adapter代码：

public class ZheKouAdapter extends BaseAdapter {private Context context;private List<ZheKouMuBan> ZheKouList;protected LayoutInflater mLayoutInflater;public ZheKouAdapter(Context context, List<ZheKouMuBan> ZheKouList) {this.context = context;this.ZheKouList = ZheKouList;mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn ZheKouList.size();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn ZheKouList.get(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn 0;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubView view = convertView;if (view == null) {view = mLayoutInflater.inflate(R.layout.mul_desk_select, null);TextView txtname = (TextView)view.findViewById(R.id.mul_deskname);ZheKouMuBan zkmb = ZheKouList.get(position);txtname.setText(zkmb.ZKMB_Name);txtname.setTextColor(Color.WHITE);txtname.setGravity(Gravity.CENTER);}return view;}
}
