小编Jam*_*ick的帖子

我已经使用了下面的代码,一切正常,但是即使我坐在同一个位置,也会调用onLocationChanged.

我认为只有当我向右移动时才应该调用它？

我只想在移动一定距离后获取位置.

请帮帮我.提前致谢.

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    locationMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    locationMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
    this);


}

    @Override
       public void onLocationChanged(Location location) {
           Toast.makeText(this, "Working!", Toast.LENGTH_SHORT).show();
                    if (location != null) {
                            double lat = location.getLatitude();
                            double lng = location.getLongitude();

                            String Text = "Latitud = " + lat + "\nLongitud = " +
     lng;

      Toast.makeText(getBaseContext(),Text,Toast.LENGTH_SHORT).show();
                    }
           }

页脚视图的末尾不显示页脚视图.请告诉我哪里出错了.足迹的代码是:

footerView = ((LayoutInflater)getBaseContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(
                R.layout.listfooter, null, false);
        list.addFooterView(footerView);

        footerView.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

            }

        });

整个代码:

public class CustomizedListView extends Activity {
    // All static variables
    static final String URL = "https://itunes.apple.com/us/rss/topalbums/limit=20/json";
    // XML node keys
    static final String KEY_SONG = "song"; // parent node
    static final String KEY_ID = "id";
    static final String KEY_TITLE = "title";
    static final String KEY_ARTIST = "artist";
    static final String KEY_DURATION = "duration";
    static …
