大家好，今天說說**Location**, **Location**在**Android**開發中還是經常用到的，比如 通過經緯度獲取天氣，根據**Location**獲取所在地區詳細**Address**（比如**Google Map**開發).等。而在**Android **中通過**LocationManager**來獲取**Location**.通常獲取**Location**有**GPS**獲取，**WIFI**獲取。 我今天做一個簡單的小**Demo**,來教大家如何獲取**Location**,從而獲取經緯度。下一節將教大家通過**Location**來獲取**Address**. ? 首先第一步: ? 創建一個**Android**工程命名為**LocationDemo**. ? 第二步：修改**main.xml**代碼如下: ~~~ <?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**，代碼如下: ~~~ 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：增加權限，修改**AndroidManifest.xml**代碼如下（第16行為所增行）： ~~~ <?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:運行**LocationDemo**工程，所得效果如下(真機深圳測試): ?
