获取位置(LocationManager)

1. 需要申请权限 xml <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

2. 代码 ```java public class TestgpsActivity extends Activity { private LocationManager lm; private MyListener listener;

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       lm = (LocationManager) getSystemService(LOCATION_SERVICE);
   
       Criteria criteria = new Criteria();
       criteria.setAccuracy(Criteria.ACCURACY_FINE);
       criteria.setCostAllowed(true);
       criteria.setPowerRequirement(Criteria.POWER_HIGH);
       criteria.setSpeedRequired(true);
       String provider = lm.getBestProvider(criteria, true);
       //第一个参数 位置提供者 第二个参数 最短更新时间 第三参数 最短的更新的距离
       listener = new MyListener();
       lm.requestLocationUpdates(provider, 0, 0, listener);
   
   }
   @Override
   protected void onDestroy() {
       lm.removeUpdates(listener);
       super.onDestroy();
   }
   
   private class MyListener implements LocationListener{
   
       /**
        * 当位置改变的时候
        */
       @Override
       public void onLocationChanged(Location location) {
           float accuracy = location.getAccuracy();
           double wlong = location.getLatitude(); //纬度
           double jlong = location.getLongitude(); //经度
   
           TextView tv = new TextView(getApplicationContext());
           tv.setText("经度:"+jlong+"\n"+"纬度:"+wlong+"\n"+ accuracy);
           setContentView(tv);
   
       }
       /**
        * 某一个位置提供者的状态发生改变的时候调用的方法
        */
       @Override
       public void onStatusChanged(String provider, int status, Bundle extras) {
   
       }
   
       @Override
       public void onProviderEnabled(String provider) {
   
       }
   
       @Override
       public void onProviderDisabled(String provider) {
   
       }
   }
   

   } ```
