Android获取经纬度

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。

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 cn.caiwb.location;      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

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