这是一个关于车载导航软件项目的问题,问题描述如下:该项目使用GPS定位,没有WiFi功能。从打印信息中可以看到LocationManagerServer已经获取到了经纬度信息。作者尝试使用自己编写的测试apk进行测试,但是发现百度地图始终无法定位。
根据提供的信息,可以生成以下重构后的代码:
```java
private void handleLocationChangedLocked(Location location, boolean passive) {
Log.w(TAG, "incoming location: " + location);
.....
}
public class MyLocationListener implements LocationListener {
private LocationManager locationManager;
private LocationListener locationListener;
@Override
public void onLocationChanged(Location location) {
// 如果位置信息为null,则请求更新位置信息
if (location == null) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
} else {
// 这里处理位置信息,例如更新地图上的位置等
.....
}
}
public MyLocationListener(Context context) {
locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
locationListener = this;
}
}
```
在这个重构后的代码中,我们创建了一个名为MyLocationListener的类,该类实现了LocationListener接口。在onLocationChanged方法中,我们首先检查传入的位置信息是否为null,如果为null,则请求更新位置信息。如果不为null,则处理位置信息,例如更新地图上的位置等。
重构后的代码如下:
```java
private void logLocation(Location location) {
Log.d("Latitude", "Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude() + ", speed: " + location.getSpeed());
}
@Override
public void onProviderDisabled(String provider) {
Log.d("Latitude", "disable");
}
@Override
public void onProviderEnabled(String provider) {
Log.d("Latitude", "enable");
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude", "status");
}
```
打开百度地图时log信息如下:
```
incoming location: Location[gps 22.583165,113.928992 acc=20 et=+1h23m11s963ms alt=59.1 {Bundle[{satellites=0}]}]
W/LocationManagerService( 1274): provider is gps
```
根据提供的内容,重构后的段落结构如下:
1. 位置更新信息:
- Location[gps 22.583165,113.928992 acc=20 et=+1h23m11s963ms {Bundle[{satellites=0}]}]
- Location[gps 22.583165,113.928992 acc=20 et=+1h23m11s963ms {Bundle[{satellites=0}]}]
2. 位置更新通知:
- W/LocationManagerService( 1274): incoming location: Location[gps 22.583165,113.928992 acc=20 et=+1h23m11s963ms {Bundle[{satellites=0}]}]
- W/LocationManagerService( 1274): prvoider is gps
3. 位置更新完成信息:
- W/LocationManagerService( 1274): complete location: Location[gps 22.583165,113.928992 acc=20 et=+1h23m11s963ms {Bundle[{satellites=0}]}]
4. 其他警告信息:
- W/LocationManagerService( 1274): synchronized
/LocationManagerService(1274): Provider is GPS
W/LocationManagerService(1274): Completed location: Location[gps 22.583165, 113.928992, acc=20, et=+1h23m11s963ms, Bundle[{satellites=0}]]
W/LocationManagerService(1274): Incoming location: Location[gps 22.583165, 113.928992, acc=20, et=+1h23m11s963ms, Bundle[{satellites=0}]]
