大家好,今天说说**Location**, **Location**在**Android**开发中还是经常用到的,比如 通过经纬度获取天气,根据**Location**获取所在地区详细**Address**(比如**Google Map**开发).等。而在**Android **中通过**LocationManager**来获取**Location**.通常获取**Location**有**GPS**获取,**WIFI**获取。 我今天做一个简单的小**Demo**,来教大家如何获取**Location**,从而获取经纬度。下一节将教大家通过**Location**来获取**Address**.   首先第一步:   创建一个**Android**工程命名为**LocationDemo**.   第二步:修改**main.xml**代码如下: ~~~ <?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><TextView android:id="@+id/longitude" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="longitude:" /><TextView android:id="@+id/latitude" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="latitude:" /></LinearLayout> ~~~   第三步:修改**LocationDemo.java**,代码如下: ~~~ package com.android.tutor;import android.app.Activity;import android.content.Context;import android.location.Location;import android.location.LocationManager;import android.os.Bundle;import android.widget.TextView;public class LocationDemo extends Activity { private TextView longitude; private TextView latitude; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); longitude = (TextView)findViewById(R.id.longitude); latitude = (TextView)findViewById(R.id.latitude); Location mLocation = getLocation(this); longitude.setText("Longitude: " + mLocation.getLongitude()); latitude.setText("Latitude: " + mLocation.getLatitude()); } //Get the Location by GPS or WIFI public Location getLocation(Context context) { LocationManager locMan = (LocationManager) context .getSystemService(Context.LOCATION_SERVICE); Location location = locMan .getLastKnownLocation(LocationManager.GPS_PROVIDER); if (location == null) { location = locMan .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); } return location; }} ~~~   第四步:增加权限,修改**AndroidManifest.xml**代码如下(第16行为所增行): ~~~ <?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.tutor" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".LocationDemo" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/></manifest> ~~~   第五步:运行**LocationDemo**工程,所得效果如下(真机深圳测试):   ![](https://box.kancloud.cn/2016-08-10_57aae5991fea6.gif)
