[Android开发]Android LocationManager

获取位置(LocationManager):

1. 需要申请权限

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

2. 代码

   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) {
   }
   }
   }
