启动设置为活动结果 [英] Starting Settings Activity for result

问题描述

在我的申请，我检查GPS是否是用户的设备上启用，如果没有，我想送他到设置让他打开它。

In my application I'm checking whether the GPS is enabled on the user's device, and if not I would like to send him to the Settings to let him turn it on.

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, LocationHelper.LOCATION_SETTINGS_REQUEST_CODE);

在用户关闭设置界面后，我就到右内执行操作的的onActivityResult（）。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == LocationHelper.LOCATION_SETTINGS_REQUEST_CODE) {
        LogUtils.d("onActivityResult from settings");
        fetchCurrentLocation();
    }
}

但是，的onActivityResult（）不会被调用。难道我做错了什么，或这种做法不一般的工作吗？先谢谢了。

However, the onActivityResult() doesn't get called. Am I doing something wrong or this approach doesn't work in general? Thanks in advance.

推荐答案

劳克设置意图：

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);

和在onResume方法获取当前的位置：

and fetch the current location in onResume method :

public void onResume(){
    super.onResume();
    if(isGPSEnabled){
         fetchCurrentLocation();
}
}

从设定画面支持后，你的onResume方法将被调用，在这里你可以获取你的位置。

after backing from setting screen , your onResume method will be call and here you can fetch your location.
