最新基于高德地图的android进阶开发（4）GPS定位之POI（Point of interesting）兴趣点源码简介

1.跑了一下高德提供的POI的源码，感觉还是比较简单的，没有达到想要的效果，还有改进的空间，后面会继续更新。

2.下面直接上代码，已经注释好了

main.java

package com.dragon.arnav.basicFuction.poi;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.TextView;

public class PoiClick extends Activity implements AMap.OnPOIClickListener,AMap.OnMarkerClickListener {
private MapView mMapView;
private AMap mAMap;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.poiclick);
mMapView = (MapView) findViewById(R.id.map);
mMapView.onCreate(savedInstanceState);
mAMap = mMapView.getMap();
//        设置监听时间
mAMap.setOnPOIClickListener(this);
mAMap.setOnMarkerClickListener(this);
}
//地图POI点击回调
@Override
public void onPOIClick(Poi poi){
mAMap.clear();
MarkerOptions markerOptions = new MarkerOptions();
//        获取坐标
markerOptions.position(poi.getCoordinate());
//        下面就是用来显示一个图标
TextView textView = new TextView(getApplicationContext());
textView.setText("到"+poi.getName()+"去");
textView.setGravity(Gravity.CENTER);
textView.setTextColor(Color.BLACK);
textView.setBackgroundResource(R.drawable.custom_info_bubble);
markerOptions.icon(BitmapDescriptorFactory.fromView(textView));
mAMap.addMarker(markerOptions);
}
//    点击Marker图标后的执行的操作
@Override
public boolean onMarkerClick(Marker marker){
//        构造导航参数
NaviPara naviPara = new NaviPara();
//        设置终点位置
naviPara.setTargetPoint(marker.getPosition());
//        设置导航策略，这里是避免拥堵
naviPara.setNaviStyle(AMapUtils.DRIVING_AVOID_CONGESTION);
try{
//            这里调用高德地图来导航
AMapUtils.openAMapNavi(naviPara,getApplicationContext());
} catch (com.amap.api.maps.AMapException e){
//            如果你没安装，这会触发这个异常
AMapUtils.getLatestAMapApp(getApplicationContext());
}
mAMap.clear();
return false;
}

//    下面这些没什么要说的
@Override
protected void onResume(){
super.onResume();
mMapView.onResume();
}
@Override
protected void onPause(){
super.onPause();
mMapView.onPause();
}
@Override
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
mMapView.onSaveInstanceState(outState);
}
@Override
protected void onDestroy(){
super.onDestroy();
mMapView.onDestroy();
}
}

main.xml

<?xml version="1.0" encoding="utf-8"?>
