1.效果图

这里写图片描述

2.先导入jar包，可以去官网下载 如图：

这里写图片描述

特别注意：其中地图和定位还有TabLayout在前面详细说过,这里就不重复了(所以复制全部会报错~)

public class MyAdapter extends CommonAdapter<PoiItem> {

    private int selectedPosition = -1;

    public MyAdapter(Context context, List<PoiItem> datas) {
        super(context, R.layout.adapter_item, datas);
    }
    public void setSelectedPosition(int position) {
        selectedPosition = position;
    }
    @Override
    protected void convert(ViewHolder holder, PoiItem poiItem, int position) {
        //名称
        String name = poiItem.getTitle();
        TextView locationName = holder.getView(R.id.location_name);
        locationName.setText(Tools.isEmpty(name) ? "-" : name);
        //距离
        int distance = poiItem.getDistance();
        //街道
        String snippet = poiItem.getSnippet();
        TextView locationInfo = holder.getView(R.id.location_info);
        locationInfo.setText(distance + "m | " + snippet);

        if (selectedPosition == position) {
            locationName.setTextColor(Color.parseColor("#1296db"));
