Android自定义单选，自定义选中状态

如图，此布局用GrildView实现，弹出框由Activity的dialog样式实现。

屏蔽系统GrildView点击背景黄色：

grildview.setSelector(new ColorDrawable(Color.TRANSPARENT));

实现数据源自定义Adapter

public class PeoPleNumAdapter extends BaseAdapter {



    public List<PeopleNum> FiltArray;

    public static HashMap<Integer, Boolean> isselected;

    LayoutInflater inflater;

    int pos;



    public PeoPleNumAdapter(Context context,List<PeopleNum> PeopleNumList,int pos) {

        super();

        inflater = LayoutInflater.from(context);

        this.FiltArray = PeopleNumList;

        this.pos = pos;

        isselected = new HashMap<Integer, Boolean>();

        initData();

    }



    public void initData() {

        for (int i = 0; i < FiltArray.size(); i++) {

            PeopleNum peo = FiltArray.get(i);

            if(i!=pos)

            getIsSelected().put(i, false);

            else

            getIsSelected().put(i, true);

        }

    }



    @Override

    public int getCount() {

        // TODO Auto-generated method stub

        return FiltArray.size();

    }



    @Override

    public Object getItem(int position) {

        // TODO Auto-generated method stub

        

            return FiltArray.get(position);

        

    }



    @Override

    public long getItemId(int position) {

        // TODO Auto-generated method stub

        return position;

    }



    @Override

    public View getView(int position, View view, ViewGroup parent) {

        // TODO Auto-generated method stub



        if (view == null) {



            view = inflater.inflate(R.layout.people_grild, null);

            TextView spec = (TextView) view.findViewById(R.id.peoplenum);

            final ImageView img = (ImageView) view.findViewById(R.id.numselect);

            PeopleNum peo = FiltArray.get(position);

            spec.setText(peo.getNum());

            if (getIsSelected().get(position)) {

                img.setVisibility(View.VISIBLE);

            } else {

                img.setVisibility(View.GONE);

            }

        }

        return view;

    }



    public static HashMap<Integer, Boolean> getIsSelected() {

        return isselected;

    }



    public static void setIsSelected(HashMap<Integer, Boolean> isSelect) {

        PeoPleNumAdapter.isselected = isSelect;

    }

}

Activity中实现点击：

grildview.setOnItemClickListener(new OnItemClickListener() {

            @Override

            public void onItemClick(AdapterView<?> parent, View view,

                    int position, long id) {

                // TODO Auto-generated method stub

                PeoPleNumAdapter.getIsSelected().put(position, true);

                adapter = new PeoPleNumAdapter(context, PeopleNumList, position);

                grildview.setAdapter(adapter);

            }

        });
