android - 模拟器控制android被禁用

Question

我正在使用 Google map v2，我想确定我的位置。我使用 Genymotion 模拟器。我需要在我的测试设备上激活 GPS。如果我正在模拟器上进行测试，并且在我尝试使用 LocationManager 时它没有激活“null”。我正在使用 Eclipse 的“DDMS”透视图将地理位置发送到模拟器。 Window → Open Perspective → Other... → DDMS。但是所有字段都不可点击。

我做了 Breadbin 说的，但我仍然有空指针异常

`

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    map=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    map.setMyLocationEnabled(true);
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider =  locationManager.getBestProvider(criteria, true);
    Location myLocation = locationManager.getLastKnownLocation(provider);
    map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
    double latitude = myLocation.getLatitude();
    double longitude = myLocation.getLongitude();
    LatLng latLng = new LatLng(latitude, longitude);
    map.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    map.animateCamera(CameraUpdateFactory.zoomTo(20));
    map.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude)).title("You are here"));
    }`

如果您使用 genymotion，您可以使用 genymotion 设置模拟位置。 IE。模拟器侧面有一个按钮，您可以在其中打开 GPS 并在 map 上设置精度和模拟位置
