如果用户选择了“从不"选项，则为Android启用位置服务 [英] Enable location services for Android if user chose Never option

问题描述

如果用户先前选择了从不"选项，是否有任何方法可以再次为应用允许位置服务(或至少显示对话框)?

Is there any way to allow location services again for an app (or at least show the dialog) if the user previously chose the option Never?

由于我总是在onResult(..)回调中获取LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE，因此我在代码中找不到再次显示它的方法:

I dont find any way in code to show it again, since i always get LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE in the onResult(..) callback:

    @Override
    public void onResult(LocationSettingsResult locationSettingsResult) {
        final Status status = locationSettingsResult.getStatus();
        switch (status.getStatusCode()) {
            case LocationSettingsStatusCodes.SUCCESS:
                Log.i(TAG, "All location settings are satisfied.");
//                        startLocationUpdates();
                break;
            case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to" +
                        "upgrade location settings ");

                try {
                    // Show the dialog by calling startResolutionForResult(), and check the result
                    // in onActivityResult().
                    status.startResolutionForResult(activity, REQUEST_CHECK_SETTINGS);

                } catch (IntentSender.SendIntentException e) {
                    Log.i(TAG, "PendingIntent unable to execute request.");
                }
                break;
            case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog " +
                        "not created.");
                break;
        }
    }

我发现的唯一解决方案是重新安装应用程序或清除数据.

The only solution i found is to reinstall the app or clear data.

推荐答案

如果用户先前选择了"从不"选项，我没有找到任何启​​用位置服务的解决方法，所以我关注@上面的Lesvmac答案要求用户再次 删除并重新安装 应用程序，但是我认为这不是解决此问题的正确方法.

I didn't find any workaround to enable location services if earlier the user had chosen "Never" option, so I followed @Lesvmac answer's above to ask user again to delete and reinstall app, but this I think isn't correct way to solve this problem around .

因此，目前最好的方法是不允许"Never"选项出现在请求对话框中.尝试添加

So at present best way is to not allow "Never" option to appear in request dialog. Try to add

builder.setAlwaysShow(true);

到 LocationSettingsRequest.Builder 只会显示"是"和"否"选项，而不是默认的"从不"，"是" & "不立即"&您将永远不会收到 SETTINGS_CHANGE_UNAVAILABLE

to LocationSettingsRequest.Builder which will result in only "Yes" and "No" option instead of default "Never", "Yes" & "Not Now" & you will never receive SETTINGS_CHANGE_UNAVAILABLE

这是完整的方法:

 private void requestSettings() {
    LocationSettingsRequest.Builder builder =
            new LocationSettingsRequest.Builder()
                    .setAlwaysShow(true)
                    .addLocationRequest(request);
    PendingResult<LocationSettingsResult> result =
            LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient,
                    builder.build());

    result.setResultCallback(this);
}
