Question

我想检测用户何时更改Android手机的GPS设置。当用户打开/关闭GPS卫星或通过接入点等进行检测时的含义。

Answer 1

我发现最好的方法是附加到

<action android:name="android.location.PROVIDERS_CHANGED" />

意图。

例如：

<receiver android:name=".gps.GpsLocationReceiver">
        <intent-filter>
            <action android:name="android.location.PROVIDERS_CHANGED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

然后在代码中：

public class GpsLocationReceiver extends BroadcastReceiver implements LocationListener 
...

@Override
public void onReceive(Context context, Intent intent)
{
        if (intent.getAction().matches("android.location.PROVIDERS_CHANGED"))
        { 
            // react on GPS provider change action 
        }
}

Answer 2

试试这个，

try {
        locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

            Log.i("About GPS", "GPS is Enabled in your devide");
        } else {
            //showAlert
        }

Answer 3

Impement android.location.LocationListener，你有两个函数

public void onProviderEnabled(String provider);
public void onProviderDisabled(String provider);

使用此功能，您可以了解所请求的提供商何时开启或关闭

Answer 4

这是一个用于广播接收器的代码示例，用于检测GPS位置的开/关事件：

private BroadcastReceiver locationSwitchStateReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {

            if (LocationManager.PROVIDERS_CHANGED_ACTION.equals(intent.getAction())) {

                LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
                boolean isGpsEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
                boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

                if (isGpsEnabled || isNetworkEnabled) {
                    //location is enabled
                } else {
                    //location is disabled
                }
            }
        }
    };

您可以动态注册BroadcastReceiver，而不用更改清单文件：

IntentFilter filter = new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION);
filter.addAction(Intent.ACTION_PROVIDER_CHANGED);
mActivity.registerReceiver(locationSwitchStateReceiver, filter);

不要忘记在onPause（）方法中注销接收器：

mActivity.unregisterReceiver(locationSwitchStateReceiver);
