（八）高德地图之添加marker标记点

高德地图上添加多个自定义的marker标记，可以用不同的图标来区分不同的种类，并且点击某个marker在marker上方弹窗显示信息，有系统弹窗，也可设置自定义弹窗。

先来张效果图看一下

布局文件activity_addmarker.xml

里面用到的存放信息的实体类MarkerListEntity

package com.junto.gdmaptest.info;

/**
 * Created by WangJinyong on 2018/12/4.
 */

public class MakerListEntity {

    private String Lat;
    private String Lng;
    private String Title;

    public String getLat() {
        return Lat;
    }

    public void setLat(String lat) {
        Lat = lat;
    }

    public String getLng() {
        return Lng;
    }

    public void setLng(String lng) {
        Lng = lng;
    }

    public String getTitle() {
        return Title;
    }

    public void setTitle(String title) {
        Title = title;
    }
}

设置点击marker的自定义弹窗CustomInfoWindowdapter

package com.junto.gdmaptest.activity;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TextView;

import com.amap.api.maps.AMap;
import com.amap.api.maps.model.Marker;
import com.junto.gdmaptest.R;

/**
 * Created by WangJinyong on 2018/12/4.
 * 自定义地图信息框
 */

public class CustomInfoWindowAdapter implements AMap.InfoWindowAdapter {

    private Context context;

    public CustomInfoWindowAdapter(Context context) {
        this.context = context;
    }

    @Override
    public View getInfoWindow(Marker marker) {
        //map_info_window布局里background  和 divider 设置InfoWindow的背景样式（颜色、图片均可），否者会使用高德默认背景
        View view = LayoutInflater.from(context).inflate(R.layout.map_info_window, null);
        setViewContent(marker, view);
        return view;
    }

    //提供了一个给默认信息窗口定制内容的方法。如果用自定义的布局，不用管这个方法。
    @Override
    public View getInfoContents(Marker marker) {
        return null;
    }

    //这个方法根据自己的实体信息来进行相应控件的赋值
    private void setViewContent(Marker marker, View view) {
        //实例：
        TextView tv_lat = view.findViewById(R.id.tv_lat);
        tv_lat.setText("lat=" + marker.getPosition().latitude);
        TextView tv_lng = view.findViewById(R.id.tv_lng);
        tv_lng.setText("lng=" + marker.getPosition().longitude);
        TextView tv_title = view.findViewById(R.id.tv_title);
        tv_title.setText("title=" + marker.getTitle());
    }
}

弹窗显示样子的布局文件map_nfo_window

在drawable里创建info_shape文件，自定义背景

在drawable里创建line_shape文件，自定义边框线

上面内容就完成了在地图上添加marker标记点了。
