首先看實(shí)現(xiàn)功能截圖，這是一個自定義Dialog,并且里面內(nèi)容由GrildView 綁定數(shù)據(jù)源，實(shí)現(xiàn)類似單選功能。

首先自定義Dialog，綁定數(shù)據(jù)源

自定義Dialog彈出框大小方法

最主要實(shí)現(xiàn)的就是點(diǎn)擊顏色切換的功能，默認(rèn)GrildView的每一項(xiàng)都是藍(lán)色背景，當(dāng)點(diǎn)擊時候切換成紅色。這里緩存了一個view,每次點(diǎn)擊給這個view重新賦值，改變顏色

數(shù)據(jù)源Adapter代碼：

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;} }
