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:


view source print ?



001. 
   public class MainActivity extends Activity {
 
  
 
   002. 
   private static final String TAG = MainActivity.class.getSimpleName();

   private double latitude = 0.0;
 
  
 
   004. 
   private double longitude = 0.0;
 
  
 
   005. 
   private TextView info;
 
  
 
   006. 
   private LocationManager locationManager;
 
  
 
   007. 
    
 
  
 
   008. 
   @Override
 
  
 
   009. 
   protected void onCreate(Bundle savedInstanceState) {
 
  
 
   010. 
   super.onCreate(savedInstanceState);
 
  
 
   011. 
   setContentView(R.layout.main);
 
  
 
   012. 
   info = (TextView) findViewById(R.id.tv);
 
  
 
   013. 
   locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
 
  
 
   014. 
   if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
 
  
 
   015. 
   getLocation();
 
  
 
   016. 
   //gps已打开
