setTestProviderLocation（）不会触发调用onLocationChanged的（） [英] setTestProviderLocation() does not trigger calling of onLocationChanged()

问题描述

我想获得code此位工作：

测试GPS Android中

现在的问题是，当我运行测试，onLocationChanged（）不会被调用：

 公共类LocationTest0扩展AndroidTestCase实现LocationListener的{
私人的位置接到= NULL;
公共无效testExample（）{
    LocationManager LM =（LocationManager）this.getContext（）getSystemService（Context.LOCATION_SERVICE）。
    字符串testProvider =测试;

    如果（空== lm.getProvider（testProvider））{
        lm.addTestProvider（testProvider，假的，假的，假的，假的，假的，假的，假的，Crit​​eria.POWER_LOW，Crit​​eria.ACCURACY_FINE）;
    }

    lm.setTestProviderEnabled（testProvider，真正的）;
    lm.requestLocationUpdates（testProvider，0，0，这一点）;
    lm.setTestProviderStatus（testProvider，LocationProvider.AVAILABLE，空，System.currentTimeMillis的（））;

    位置位置=新的位置（testProvider）;
    location.setLatitude（1.0）;
    location.setLongitude（2.0）;
    location.setTime（System.currentTimeMillis的（））;
    lm.setTestProviderLocation（testProvider，位置）;

    Assert.assertFalse（接收的位置是空，收到== NULL）;

    lm.removeTestProvider（testProvider）;
}
@覆盖
公共无效onLocationChanged（位置定位）{
    收到=位置;
    Log.d（LocationTest0，onLocationChanged叫做）;
    //不会被调用
}
 

解决方案

这是为我工作。

  locationManager.addTestProvider（mocLocationProvider，假的，假的，
                    假的，假的，真正的，真实的，真实的，0,5）;
locationManager.setTestProviderEnabled（mocLocationProvider，真正的）;
 

 位置mockLocation =新的位置（mocLocationProvider）; //字符串
mockLocation.setLatitude（location.getLatitude（））; // 双
mockLocation.setLongitude（location.getLongitude（））;
mockLocation.setAltitude（location.getAltitude（））;
mockLocation.setTime（System.currentTimeMillis的（））;
locationManager.setTestProviderLocation（mocLocationProvider，mockLocation）;
 

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.ACCESS_MOCK_LOCATION＆GT;
 

另外，在Android手机上设置确保您有允许模拟位置复选框勾选

I'm trying to get this bit of code to work:

Testing GPS in Android

The problem is, when I run the test, onLocationChanged() is never called:

public class LocationTest0 extends AndroidTestCase implements LocationListener {
private Location received = null;
public void testExample() {
    LocationManager lm = (LocationManager)this.getContext().getSystemService(Context.LOCATION_SERVICE);
    String testProvider = "Test";

    if (null == lm.getProvider(testProvider)){
        lm.addTestProvider(testProvider, false, false, false, false, false, false, false, Criteria.POWER_LOW, Criteria.ACCURACY_FINE);
    }

    lm.setTestProviderEnabled(testProvider, true);
    lm.requestLocationUpdates(testProvider, 0, 0, this);
    lm.setTestProviderStatus(testProvider, LocationProvider.AVAILABLE, null, System.currentTimeMillis());

    Location location = new Location(testProvider);
    location.setLatitude(1.0);
    location.setLongitude(2.0);
    location.setTime(System.currentTimeMillis());
    lm.setTestProviderLocation(testProvider, location);

    Assert.assertFalse("Received Location is null", received == null );

    lm.removeTestProvider(testProvider);
}
@Override
public void onLocationChanged(Location location) {
    received = location;
    Log.d("LocationTest0", "onLocationChanged CALLED");
    // Never gets called
}

解决方案

This is what worked for me

locationManager.addTestProvider(mocLocationProvider, false, false,
                    false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(mocLocationProvider, true);

.

Location mockLocation = new Location(mocLocationProvider); // a string
mockLocation.setLatitude(location.getLatitude());  // double 
mockLocation.setLongitude(location.getLongitude()); 
mockLocation.setAltitude(location.getAltitude()); 
mockLocation.setTime(System.currentTimeMillis()); 
locationManager.setTestProviderLocation( mocLocationProvider, mockLocation); 

.

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION">

Also in the android phone settings make sure you have the "Allow mock locations" checkbox ticked
