在设置中收听位置访问禁用/启用

在Android操作系统中,在“设置”中 - > “位置服务”,有一个名为“访问我的位置”的切换按钮,可用于禁用&启用应用程序的位置信息访问。

目前,我正在开发一个位置服务应用程序。我想知道,我怎么能在我的Android项目中听这个设置?当用户禁用或启用“访问我的位置”时,是否有任何广播接收器可以立即知道?

如果没有任何广播接收器,我如何在Android项目中收听此更改?

这对我有用:

将接收器添加到清单文件:

<receiver
        android:name="com.eegeo.location.LocationProviderChangedReceiver">
        <intent-filter>
            <action android:name="android.location.PROVIDERS_CHANGED" />
        </intent-filter>
    </receiver>

检查接收方中的两个位置提供者:

public class LocationProviderChangedReceiver  extends BroadcastReceiver{

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

        boolean anyLocationProv = false;
        LocationManager locationManager = (LocationManager) MyMainActivity.context.getSystemService(Context.LOCATION_SERVICE);

        anyLocationProv |= locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        anyLocationProv |=  locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        Log.i("", "Location service status" + anyLocationProv);


    }

}

虽然这个接收器由于显而易见的原因被多次调用,但这会告诉你状态。

你可以通过这种方式更简单地做到这一点。在您的BroadcastReceiver的 onReceive()方法中:

    ContentResolver contentResolver = getContext().getContentResolver();
    // Find out what the settings say about which providers are enabled
    int mode = Settings.Secure.getInt(
            contentResolver, Settings.Secure.LOCATION_MODE, Settings.Secure.LOCATION_MODE_OFF);

    if (mode == Settings.Secure.LOCATION_MODE_OFF) {
        // Location is turned OFF!
    } else {
        // Location is turned ON!
    }

您可以使用以下代码检查是否启用位置服务

 LocationManager lm = null;
 boolean gps_enabled,network_enabled;
    if(lm==null)
        lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    try{
    gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    }catch(Exception ex){}
    try{
    network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    }catch(Exception ex){}

   if(!gps_enabled && !network_enabled){
        dialog = new AlertDialog.Builder(context);
        dialog.setMessage(context.getResources().getString(R.string.gps_network_not_enabled));
        dialog.setPositiveButton(context.getResources().getString(R.string.open_location_settings), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub
                Intent myIntent = new Intent( Settings.ACTION_SECURITY_SETTINGS );
                context.startActivity(myIntent);
                //get gps
            }
        });
        dialog.setNegativeButton(context.getString(R.string.Cancel), new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub

            }
        });
        dialog.show();

    }
