高德地图导航添加需要添加特定的navi包。
高德地图开发中添加导航功能的简单实现原理是引入自定义起点和终点数据后调用官方给出的demo代码。
首先需要一个baseactivity类,给出代码:
package com.example.maptest;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.widget.Toast;
import com.amap.api.navi.AMapNavi;
import com.amap.api.navi.AMapNaviListener;
import com.amap.api.navi.AMapNaviView;
import com.amap.api.navi.AMapNaviViewListener;
import com.amap.api.navi.model.AMapLaneInfo;
import com.amap.api.navi.model.AMapNaviCross;
import com.amap.api.navi.model.AMapNaviInfo;
import com.amap.api.navi.model.AMapNaviLocation;
import com.amap.api.navi.model.AMapNaviStaticInfo;
import com.amap.api.navi.model.AMapNaviTrafficFacilityInfo;
import com.amap.api.navi.model.AimLessModeCongestionInfo;
import com.amap.api.navi.model.AimLessModeStat;
import com.amap.api.navi.model.NaviInfo;
import com.amap.api.navi.model.NaviLatLng;
import com.amap.navi.demo.util.TTSController;
import com.autonavi.tbt.NaviStaticInfo;
import com.autonavi.tbt.TrafficFacilityInfo;
import java.util.ArrayList;
import java.util.List;
public class BaseActivity extends Activity implements AMapNaviListener,
AMapNaviViewListener {
protected AMapNaviView mAMapNaviView;
protected AMapNavi mAMapNavi;
protected TTSController mTtsManager;
protected NaviLatLng mEndLatlng = new NaviLatLng(32.1194970000,
118.9709290000);//自定义的起点
protected NaviLatLng mStartLatlng = new NaviLatLng(32.0865760000,
118.7775490000);//自定义的终点
protected final List sList = new ArrayList();
protected final List eList = new ArrayList();
protected List mWayPointList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
mTtsManager = TTSController.getInstance(getApplicationContext());
mTtsManager.init();
//
mAMapNavi = AMapNavi.getInstance(getApplicationContext());
mAMapNavi.addAMapNaviListener(this);
mAMapNavi.addAMapNaviListener(mTtsManager);
// 设置模拟导航的行车速度
mAMapNavi.setEmulatorNaviSpeed(75);
sList.add(mStartLatlng);//自定义起点加入起点集合
eList.add(mEndLatlng);//自定义终点加入终点集合
}
@Override
protected void onResume() {
super.onResume();
mAMapNaviView.onResume();
}
@Override
protected void onPause() {
super.onPause();
mAMapNaviView.onPause();
// 仅仅是停止你当前在说的这句话,一会到新的路口还是会再说的
mTtsManager.stopSpeaking();
//
// 停止导航之后,会触及底层stop,然后就不会再有回调了,但是讯飞当前还是没有说完的半句话还是会说完
// mAMapNavi.stopNavi();
}
@Override
protected void onDestroy() {
super.onDestroy();
mAMapNaviView.onDestroy();
// since 1.6.0 不再在naviview destroy的时候自动执行AMapNavi.stopNavi();请自行执行
mAMapNavi.stopNavi();
mAMapNavi.destroy();
mTtsManager.destroy();
}
@Override
public void onInitNaviFailure() {
Toast.makeText(this, "init navi Failed", Toast.LENGTH_SHORT).show();

}
在我们自己定义的导航类中,我们需要继承baseactivity类来实现功能,从跳转来的页面获取起点和终点的经度和纬度信息,在onInitNaviSuccess方法中清空起点和终点集合分别放入起点和终点坐标即可。给出GPSNaviActivity类代码:
package com.example.maptest;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.amap.api.navi.AMapNaviView;
import com.amap.api.navi.enums.NaviType;
import com.amap.api.navi.model.NaviLatLng;
public class GPSNaviActivity extends BaseActivity {
// 继承的是baseactivity
private double sj;
private double sw;
private double ej;
private double ew;
private String ssj;
private String ssw;
private String sej;
private String sew;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
ssj = intent.getStringExtra("sj");
sj = Double.parseDouble(ssj);
ssw = intent.getStringExtra("sw");
sw = Double.parseDouble(ssw);
sej = intent.getStringExtra("ej");
ej = Double.parseDouble(sej);
sew = intent.getStringExtra("ew");
ew = Double.parseDouble(sew);
setContentView(R.layout.activity_basic_navi);
mAMapNaviView = (AMapNaviView) findViewById(R.id.navi_view);
mAMapNaviView.onCreate(savedInstanceState);
mAMapNaviView.setAMapNaviViewListener(this);
}
@Override
public void onInitNaviSuccess() {
super.onInitNaviSuccess();
/**
* 方法: int strategy=mAMapNavi.strategyConvert(congestion,
* avoidhightspeed, cost, hightspeed, multipleroute); 参数:
*
* @congestion 躲避拥堵
* @avoidhightspeed 不走高速
* @cost 避免收费
* @hightspeed 高速优先
* @multipleroute 多路径
*
* 说明: 以上参数都是boolean类型,其中multipleroute参数表示是否多条路线,
* 如果为true则此策略会算出多条路线。 注意: 不走高速与高速优先不能同时为true
* 高速优先与避免收费不能同时为true
*/
// 重置起点
this.sList.clear();
this.mStartLatlng = new NaviLatLng(sw, sj);
this.sList.add(mStartLatlng);
// 重置了终点
this.eList.clear();
this.mEndLatlng = new NaviLatLng(ew, ej);
this.eList.add(mEndLatlng);
int strategy = 0;
try {
// 再次强调,最后一个参数为true时代表多路径,否则代表单路径
strategy = mAMapNavi.strategyConvert(true, false, false, false,
false);
} catch (Exception e) {
e.printStackTrace();
}
mAMapNavi.calculateDriveRoute(sList, eList, mWayPointList, strategy);
}
@Override
public void onCalculateRouteSuccess() {
super.onCalculateRouteSuccess();
mAMapNavi.startNavi(NaviType.GPS);
}
}
在上述代码中,我根据前一页面传入的起点和终点的值调用gps导航,具体原理参见代码。
特记下,以备后日回顾。
