問題描述

美好的一天！我正在開發(fā)一個(gè)監(jiān)控用戶位置的安卓應(yīng)用程序.我正在使用 LocationManager 獲取用戶位置，使用以下方法

Good Day! I am working on an android app which monitors user location. I am using LocationManager to get users location, using the following method

public void onLocationChanged(Location theLocation) {}

通過上述方法，每當(dāng)有用戶移動(dòng)時(shí)，我都會(huì)收到位置坐標(biāo).

Through the above method, whenever there was a user movement, I am receiving location coordinates.

但是，現(xiàn)在我計(jì)劃在用戶登錄應(yīng)用后立即獲取用戶的位置.有什么方法可以通過 LocationManager 在我的應(yīng)用啟動(dòng)后手動(dòng)獲取位置坐標(biāo)?

But, now I am planning to get user's location immediately after their app login. Is there any way through LocationManager through which I can manually get the location coordinates after my app launch?

推薦答案

使用這個(gè)技巧:

LocationManager locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

boolean network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

Location location;

if(network_enabled){

   location = locManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

if(location!=null){
   longitude = location.getLongitude();
   latitude = location.getLatitude();
    }                
}

在這種情況下，您甚至不需要使用 GPS，只需移動(dòng)網(wǎng)絡(luò)即可.

In this case you even no need to on GPS only your mobile network will do.

別忘了在 Manifest 中給予以下權(quán)限:

Don't forget to give the following permission in Manifest:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

這篇關(guān)于在應(yīng)用啟動(dòng)期間獲取當(dāng)前位置的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
