Question

我正在尝试制作一个简单的Android应用程序来确定GPS的当前位置，但是当我在手机上运行应用程序时，它只是给了我准确性而没有给出真实的坐标这里是我的代码

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    v1 = (TextView) findViewById(R.id.textView1);
    v2 = (TextView) findViewById(R.id.textView1);
    v3 = (TextView) findViewById(R.id.textView1);

    int GpsUpdateInterval = 60 * 1000; 
    int GpsUpdateRadius = 15;

    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
            GpsUpdateInterval, GpsUpdateRadius, new LocationListener() {

        @Override
                public void onStatusChanged(String provider, int status,
                        Bundle exras) {
                }

                @Override
                public void onProviderEnabled(String provider) {
                }

                @Override
                public void onProviderDisabled(String provider) {
                }

                @Override
                public void onLocationChanged(Location location) {
                    // this function trigger when a new location founded
                    v1.setText("Lat "
                            + String.valueOf(location.getLatitude()));
                    v2.setText("Lng "
                            + String.valueOf(location.getLongitude()));
                    v3.setText("Accurcy "
                            + String.valueOf(location.getAccuracy()));

                }
            });

}

Answer 1

v1 = (TextView) findViewById(R.id.textView1);
v2 = (TextView) findViewById(R.id.textView1);
v3 = (TextView) findViewById(R.id.textView1);

你的视图绑定不好;）

位置管理器不工作
