获取位置(LocationManager)

需要申请权限

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

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
         */
