有什么方法可以强制在 android 中设置位置以启用 vai 应用程序

Question

我正在创建一个需要激活位置服务的 android 应用。有什么办法可以强制在android中启用位置服务。我不希望用户进入设置页面并启用它。

PS：该应用不适合公众使用，如果需要，可以为该应用提供 root 访问权限。

试试这个：

public static void locationChecker(GoogleApiClient googleApiClient, final Activity activity) {
        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        locationRequest.setInterval(30 * 1000);
        locationRequest.setFastestInterval(5 * 1000);
        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(locationRequest);
        builder.setAlwaysShow(true);
        PendingResult<LocationSettingsResult> result =
                LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
        result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
                                     @Override
                                     public void onResult(LocationSettingsResult result) {
                                         final Status status = result.getStatus();
                                         final LocationSettingsStates state = result.getLocationSettingsStates();
                                         switch (status.getStatusCode()) {
                                             case LocationSettingsStatusCodes.SUCCESS:
                                                 // All location settings are satisfied. The client can initialize location
                                                 // requests here.
                                                 break;
                                             case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                                                 // Location settings are not satisfied. But could be fixed by showing the user
                                                 // a dialog.
                                                 try {

                                                     // Show the dialog by calling startResolutionForResult(),
                                                     // and check the result in onActivityResult().
                                                     status.startResolutionForResult(
                                                             activity, 1000);
                                                 } catch (IntentSender.SendIntentException e) {
                                                     // Ignore the error.
                                                 }
                                                 break;
                                             case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                                                 // Location settings are not satisfied. However, we have no way to fix the
                                                 // settings so we won't show the dialog.
                                                 break;
                                         }
                                     }
                                 }

        );
    }

在您的 Activity 中，将以下代码放入 onActivityResult()：

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
         if (requestCode == 1000) {
            if (resultCode == Activity.RESULT_CANCELED) {
                finish();
            } else {
                // this should not be needed, but apparently is in 8.1
                //user granted the permission
            }
        }

    }
