使用百度地圖進行android開發

百度定位

修改AndroidManifest.xml

<meta-data
  android:name="com.baidu.lbsapi.API_KEY"
  android:value="密鑰"/>

<service android:name="com.baidu.location.f" android:enabled="true"
  android:process=":remote">
</service>

確定自己的經緯度

public LocationClient mLocationClient;
mLocationClient = new LocationClient(getApplicationContext());
mLocationClient.registerLocationListener(new LocationListener());

private void requestLocation() {
    //initLocation();
    mLocationClient.start();
}

public class MyLocationListener implements BDLocationListener{
  @Override
  public void onReceiveLocation(BDLocation location){
    //自行發揮
    //location.getLatitude();
    //location.getLongitude();
  }
}

實時更新位置信息、定位模式、看得懂的位置信息

private void initLocation(){
    LocationClientOption option = new LocationClientOption();

    //設置每隔5秒更新一次
    option.setScanSpan(5000);

    //設置定位模式爲只使用GPS定位。另外兩種Hight_Accuracy和Battery_Saving
    option.setLocationMode(LocationClientOption.LocationMode.Device_Sensors);     

    //設置看得懂的位置信息  在MyLocationListener中可以獲得其他位置信息，如省市街道等。
    option.setIsNeedAddress(true);

    mLocationClient.setLocOption(option);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mLocationClient.stop();     //停止定位
    // mapView.onDestroy();
    // baiduMap.setMyLocationEnabled(false);
}

使用百度地圖

顯示地圖

<com.baidu.mapapi.map.MapView
  android:id="@+id/bmapView"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:clickable="true" />

SDKInitiaLizer.initialize(getApplicationContext());
mapView = (MapView)findViewById(R.id.bmapView);

@Override
 protected void onResume() {
     super.onResume();
     mapView.onResume();
 }

 @Override
 protected void onPause() {
     super.onPause();
     mapView.onPause();
 }

 @Override
 protected void onDestroy() {
    //  super.onDestroy();
    //  mLocationClient.stop();     //停止定位
     mapView.onDestroy();
    //  baiduMap.setMyLocationEnabled(false);
 }

移動到我的位置

private boolean isFirstLocate = true;

//地圖總控制器
BaiduMap baiduMap = mapView.getMap();
baiduMap.setMyLocationEnabled(true);

private void navigateTo(BDLocation location) {
if (isFirstLocate) {

    //定位到經緯度
    LatLng ll = new LatLng(location.getLatitude(), location.getLongitude());
    MapStatusUpdate update = MapStatusUpdateFactory.newLatLng(ll);
    baiduMap.animateMapStatus(update);

    //縮放
    update = MapStatusUpdateFactory.zoomTo(16f);
    baiduMap.animateMapStatus(update);

    isFirstLocate = false;
}

//讓“我”顯示在地圖上
MyLocationData.Builder locationBuilder = new MyLocationData.
        Builder();
locationBuilder.latitude(location.getLatitude());
locationBuilder.longitude(location.getLongitude());
MyLocationData locationData = locationBuilder.build();
baiduMap.setMyLocationData(locationData);

}

public class MyLocationListener implements BDLocationListener {

@Override
public void onReceiveLocation(BDLocation location) {
    if (location.getLocType() == BDLocation.TypeGpsLocation
            || location.getLocType() == BDLocation.TypeNetWorkLocation) {
        navigateTo(location);
    }
}

}

@Override
protected void onDestroy() {
super.onDestroy();
// mLocationClient.stop();
// mapView.onDestroy();
baiduMap.setMyLocationEnabled(false);
}
