APP中可能会遇到一种需求，就是将当前所在位置的坐标传到服务器上，今天我提供三种途径去获取经纬度坐标信息，第一种是通过Android API来实现，第二种通过百度地图API来实现，第三种通过天地图API来实现。

第一种方法（Android API实现），废话不多说，上代码。

MainActivity代码如下：

public class MainActivity extends Activity { private static final String TAG = MainActivity.class.getSimpleName(); private double latitude = 0.0; private double longitude = 0.0; private TextView info; private LocationManager locationManager;  @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); info = (TextView) findViewById(R.id.tv); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { getLocation(); //gps已打开 } else { toggleGPS(); new Handler() { }.postDelayed(new Runnable() { @Override public void run() {  getLocation(); } }, 2000);  } }  private void toggleGPS() { Intent gpsIntent = new Intent(); gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); gpsIntent.addCategory("android.intent.category.ALTERNATIVE"); gpsIntent.setData(Uri.parse("custom:3")); try { PendingIntent.getBroadcast(this, 0, gpsIntent, 0).send(); } catch (CanceledException e) { e.printStackTrace(); locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 0, locationListener); Location location1 = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); if (location1 != null) { latitude = location1.getLatitude(); // 经度 longitude = location1.getLongitude(); // 纬度 } } }  private void getLocation() { Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); if (location != null) { latitude = location.getLatitude(); longitude = location.getLongitude(); } else {  locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, locationListener); } info.setText("纬度：" + latitude + "/n" + "经度：" + longitude); }  LocationListener locationListener = new LocationListener() { // Provider的状态在可用、暂时不可用和无服务三个状态直接切换时触发此函数 @Override public void onStatusChanged(String provider, int status, Bundle extras) { }  // Provider被enable时触发此函数，比如GPS被打开 @Override public void onProviderEnabled(String provider) { Log.e(TAG, provider); }  // Provider被disable时触发此函数，比如GPS被关闭 @Override public void onProviderDisabled(String provider) { Log.e(TAG, provider); }  // 当坐标改变时触发此函数，如果Provider传进相同的坐标，它就不会被触发 @Override public void onLocationChanged(Location location) { if (location != null) { Log.e("Map", "Location changed : Lat: " + location.getLatitude() + " Lng: " + location.getLongitude()); latitude = location.getLatitude(); // 经度 longitude = location.getLongitude(); // 纬度 } } };  /* *  * 打开和关闭gps第二种方法 * private void openGPSSettings() { //获取GPS现在的状态（打开或是关闭状态） boolean gpsEnabled = Settings.Secure.isLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER); if (gpsEnabled) { //关闭GPS Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, false); } else { //打开GPS  Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, true); } }*/}

main.xml布局如下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/layout" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/white" android:orientation="vertical" >  <TextView  android:id="@+id/tv"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:text="经纬度信息："  android:textColor="#660000"  android:textSize="20sp" /> </LinearLayout>

清单文件如下：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.tqmapdemo" android:versionCode="1" android:versionName="1.0" > <uses-sdk  android:minSdkVersion="8"  android:targetSdkVersion="18" />  <!-- 连接互联网Internet权限 --> <uses-permission android:name="android.permission.INTERNET" /> <!-- GPS定位权限 --> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />  <application  android:allowBackup="true"  android:icon="@drawable/ic_launcher"  android:label="@string/app_name"  android:theme="@android:style/Theme.Black" >  <activity   android:name="com.example.tqmapdemo.MainActivity"   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></manifest>

运行结果如下
