【问题描述】：

我正在尝试测试使用 GPS 位置更新的应用。当我无法获得任何 GPS 信号时，我试图通过模拟设备的位置使其在室内工作。我按照教程 here 进行操作，但是当我的应用程序运行时，它仍然没有获取任何位置更新。

谁能发现我的代码有什么问题？

        MockLocationProvider mock = new MockLocationProvider(LocationManager.GPS_PROVIDER, this);
        mock.pushLocation(-12.34, 23.45);

        LocationManager locMgr;

        locMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    

    @Override
    public void onLocationChanged(Location Loc) 
        double lat = Loc.getLatitude();
        double lon = Loc.getLongitude();
        String l = "Longitude: " + lon + " Latitude: " + lat;
        Toast.makeText(getApplicationContext(), l ,Toast.LENGTH_SHORT).show();
    


public class MockLocationProvider 
        String providerName;
        Context ctx;

        public MockLocationProvider(String name, Context ctx) 
            this.providerName = name;
            this.ctx = ctx;

            LocationManager lm = (LocationManager) ctx.getSystemService(
                    Context.LOCATION_SERVICE);
            lm.addTestProvider(providerName, false, false, false, false, false,
                    true, true, 0, 5);
            lm.setTestProviderEnabled(providerName, true);
        

        public void pushLocation(double lat, double lon) 
            LocationManager lm = (LocationManager) ctx.getSystemService(
                    Context.LOCATION_SERVICE);

            Location mockLocation = new Location(providerName);
            mockLocation.setLatitude(lat);
            mockLocation.setLongitude(lon);
            mockLocation.setAltitude(0);
            mockLocation.setTime(System.currentTimeMillis());
            mockLocation.setElapsedRealtimeNanos(System.currentTimeMillis());
            mockLocation.setAccuracy(2);
            lm.setTestProviderLocation(providerName, mockLocation);
        

【参考方案1】：

当您的代码监听位置更新时，您应该同时模拟位置。

在您的情况下，每当您调用 pushLocation 方法时，都会触发 onLocationChanged 方法。

监听 GPS

 @Override
public void onLocationChanged(Location Loc) 
    double lat = Loc.getLatitude();
    double lon = Loc.getLongitude();
    String l = "Longitude: " + lon + " Latitude: " + lat;
    Toast.makeText(getApplicationContext(), l ,Toast.LENGTH_SHORT).show();

模拟一下

Handler mHandler = new Handler();
public void loopMock()
    mHandler.postDelayed(new Runnable() 
        @Override
        public void run() 
            // onLocationChanged method will be fired
            mock.pushLocation(-12.34, 23.45);
            mHandler.postDelayed(this, 1000);
        
    , 1000);
