如果用户选择了“从不"选项,则为Android启用位置服务
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.
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);
}
