三步实现地图自定义InfoWindow

项目地址：https://github.com/teprinciple/AMapInfoWindowDemo

前言

现在的app很多都需要接入地图，不同的app都会定义自己的marker以及InforWindow，本文以高德地图为例，描述自己自定义InfoWindow之路。
先看看效果图：

高德地图的SDK以及接入流程，官方文档已经写的很明白了：http://lbs.amap.com/

第一步：自定义InforWindow的布局

第二步、自定义适配器

需要继承高德地图的AMap.InfoWindowAdapter

package teprinciple.yang.amapinforwindowdemo.adapter;

import android.content.Context;
import android.support.annotation.NonNull;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.amap.api.maps2d.AMap;
import com.amap.api.maps2d.model.LatLng;
import com.amap.api.maps2d.model.Marker;

import teprinciple.yang.amapinforwindowdemo.base.BaseApplication;
import teprinciple.yang.amapinforwindowdemo.R;
import teprinciple.yang.amapinforwindowdemo.utils.NavigationUtils;
import teprinciple.yang.amapinforwindowdemo.utils.PhoneCallUtils;


/**
 * Created by Teprinciple on 2016/8/23.
 * 地图上自定义的infowindow的适配器
 */
public class InfoWinAdapter implements AMap.InfoWindowAdapter, View.OnClickListener {
    private Context mContext = BaseApplication.getIntance().getBaseContext();;
    private LatLng latLng;
    private LinearLayout call;
    private LinearLayout navigation;
    private TextView nameTV;
    private String agentName;
    private TextView addrTV;
    private String snippet;

    @Override
    public View getInfoWindow(Marker marker) {
        initData(marker);
        View view = initView();
        return view;
    }
    @Override
    public View getInfoContents(Marker marker) {
        return null;
    }

    private void initData(Marker marker) {
        latLng = marker.getPosition();
        snippet = marker.getSnippet();
        agentName = marker.getTitle();
    }

    @NonNull
    private View initView() {
        View view = LayoutInflater.from(mContext).inflate(R.layout.view_infowindow, null);
        navigation = (LinearLayout) view.findViewById(R.id.navigation_LL);
        call = (LinearLayout) view.findViewById(R.id.call_LL);
        nameTV = (TextView) view.findViewById(R.id.name);
        addrTV = (TextView) view.findViewById(R.id.addr);

        nameTV.setText(agentName);
        addrTV.setText(String.format(mContext.getString(R.string.agent_addr),snippet));

        navigation.setOnClickListener(this);
        call.setOnClickListener(this);
        return view;
    }


    @Override
    public void onClick(View v) {
        int id = v.getId();
        switch (id){
            case R.id.navigation_LL:  //点击导航
                NavigationUtils.Navigation(latLng);
                break;

            case R.id.call_LL:  //点击打电话
                PhoneCallUtils.call("028-"); //TODO 处理电话号码
                break;
        }
    }
}

第三步、调用

package teprinciple.yang.amapinforwindowdemo;

import android.os.Bundle;
import android.util.Log;

import com.amap.api.location.AMapLocation;
import com.amap.api.location.AMapLocationClient;
import com.amap.api.location.AMapLocationClientOption;
import com.amap.api.location.AMapLocationListener;
import com.amap.api.maps2d.AMap;
import com.amap.api.maps2d.CameraUpdateFactory;
import com.amap.api.maps2d.MapView;
import com.amap.api.maps2d.UiSettings;
import com.amap.api.maps2d.model.BitmapDescriptorFactory;
import com.amap.api.maps2d.model.LatLng;
import com.amap.api.maps2d.model.Marker;
import com.amap.api.maps2d.model.MarkerOptions;

import teprinciple.yang.amapinforwindowdemo.adapter.InfoWinAdapter;
import teprinciple.yang.amapinforwindowdemo.base.BaseActivity;
import teprinciple.yang.amapinforwindowdemo.entity.Constant;
import teprinciple.yang.amapinforwindowdemo.utils.CheckPermissionsActivity;

public class MainActivity extends CheckPermissionsActivity implements AMap.OnMapClickListener, AMap.OnMarkerClickListener {

    private MapView mapView;
    private AMap aMap;
    private UiSettings uiSettings;
    private InfoWinAdapter adapter;
    private Marker oldMarker;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        //在执行onCreateView时执行mMapView.onCreate(savedInstanceState)，实现地图生命周期管理
        mapView.onCreate(savedInstanceState);
        initOperation();
    }

    private void initView() {
        mapView = (MapView) initV(R.id.mapView);
    }

    private void initOperation() {
        initMap();
    }

    /**
     * 初始化地图
     */
    private void initMap() {
        if (aMap == null) {
            aMap = mapView.getMap();
            uiSettings = aMap.getUiSettings();
            aMap.setOnMapClickListener(this);
        }
        uiSettings.setZoomControlsEnabled(false); //隐藏缩放控件
        //自定义InfoWindow
        aMap.setOnMarkerClickListener(this);
        adapter = new InfoWinAdapter();
        aMap.setInfoWindowAdapter(adapter);

        addMarkerToMap(Constant.CHENGDU,"成都","中国四川省成都市");
    }

    @Override
    public void onResume() {
        super.onResume();
        mapView.onResume(); //管理地图的生命周期
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause(); //管理地图的生命周期
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mapView.onDestroy(); //管理地图的生命周期
    }

    //地图的点击事件
    @Override
    public void onMapClick(LatLng latLng) {
        //点击地图上没marker 的地方，隐藏inforwindow
        if (oldMarker != null) {
            oldMarker.hideInfoWindow();
            oldMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal));
        }
    }

    //maker的点击事件
    @Override
    public boolean onMarkerClick(Marker marker) {
        if (oldMarker != null) {
            oldMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal));
        }
        oldMarker = marker;
        marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_selected));
        return false; //返回 “false”，除定义的操作之外，默认操作也将会被执行
    }

    private void addMarkerToMap(LatLng latLng, String title, String snippet) {
        aMap.addMarker(new MarkerOptions().anchor(0.5f, 0.5f)
                .position(latLng)
                .title(title)
                .snippet(snippet)
                .icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal))
        );
    }
}

特别注意

显示infowindow必须设置title或者sinnipet，同时设置aMap.setInfoWindowAdapter(this)

后记

项目地址：https://github.com/teprinciple/AMapInfoWindowDemo
项目中还包括以下功能（均已适配6.0）：
1、跳转到高德地图进行导航功能
2、定位功能
