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%26lt;ZheKouMuBan%26gt; ZheKouList;
protected LayoutInflater mLayoutInflater;

public ZheKouAdapter(Context context, List%26lt;ZheKouMuBan%26gt; ZheKouList) {
this.context = context;
this.ZheKouList = ZheKouList;
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
// TODO Auto-generated method stub
return ZheKouList.size();
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return ZheKouList.get(position);
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View 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;
}
}
