MyLocationOverlay不是要求onProviderDisabled [英] MyLocationOverlay not calling onProviderDisabled

问题描述

这是我的code，其行为有些奇怪：

This is my code that behaves a little strange:

locationOverlay = new MyLocationOverlay(this, map) {
    @Override
    public void onLocationChanged(Location location) {
        super.onLocationChanged(location);
        updatePosition(locationOverlay.getMyLocation());
    }

    @Override
    public void onProviderDisabled(String provider) {
        if(provider.equals(LocationManager.GPS_PROVIDER))
            showNoGPSWarning();
    }
};

showNoGPSWarning 显示一个对话框，询问是否GPS应该启用（如这）。结果
一切wokrs完全正常，除非我开始活动与在 showNoGPSWarning（）对话框GPS残疾人和preSS否。然后，我的应用程序不听GPS变化的。

showNoGPSWarning shows a Dialog that asks if GPS should be enabled (like this).
Everything wokrs perfectly fine except if I start the Activity with GPS disabled and press "No" in the showNoGPSWarning() dialog. Then my App doesn't listen to GPS changes at all.

如果我打开它，什么都不会发生。谷歌地图API不尝试获取GPS信号。如果我把它背过，没有再次发生， onProviderDisabled（）不叫。结果
正如我所说的，这是出现这种情况的唯一途径，如果我它工作在对话框中preSS是。结果
因此，如何影响我的对话我的应用程序的行为？

If I turn it on, nothing happens. The Google maps API doesn't try to get a GPS signal. If I turn it back off, nothing happens again, onProviderDisabled() is not called.
As I said, this is the only way that happens, if I press "Yes" in the dialog it works.
So how is my dialog affecting the behavior of my App?.

推荐答案

再次尝试请求位置更新时，您preSS是/否像下面。希望它帮助。

Once again try to request for location updates when you press yes/no like below. Hope it helps.

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 2000.0f, myLocationListener);
