Question

我正在开发一个基于Tabbar导航模型的Android应用程序。我的应用程序的一个视图包含一个“3列”gridview，其中包含10个元素，我只能看到9个元素，我无法滚动。

这是我的代码：

MoreFragment.java

public class MoreFragment extends Fragment implements
    AdapterView.OnItemClickListener {

static final String EXTRA_MAP = "map";

static final LauncherIcon[] ICONS = {
        new LauncherIcon(R.drawable.casino, "Casino", "casino.png"),
        new LauncherIcon(R.drawable.cinema, "Cinema", "cinema.png"),
        new LauncherIcon(R.drawable.quad, "Quad", "quad.png"),
        new LauncherIcon(R.drawable.tennis, "Tennis", "tennis.png"),
        new LauncherIcon(R.drawable.golf, "Golf", "golf.png"),
        new LauncherIcon(R.drawable.club, "Club", "club.png"),
        new LauncherIcon(R.drawable.jazz, "Jazz Bar", "jazz.jpg"),
        new LauncherIcon(R.drawable.pool, "Pool", "pool.png"),
        new LauncherIcon(R.drawable.ic_7, "Map" ,"ic_7.png"),
        new LauncherIcon(R.drawable.fono,"Contact" ,"fono.png")


};

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.gridview, null);

    GridView gridview = (GridView) view.findViewById(R.id.dashboard_grid);
    gridview.setAdapter(new ImageAdapter(getActivity()));
    gridview.setOnItemClickListener(this);


    gridview.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return event.getAction() == MotionEvent.ACTION_MOVE;
        }
    });
    return view;
}

@Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

    FragmentManager fm2 = getActivity().getSupportFragmentManager();
    FragmentTransaction ft2 = fm2.beginTransaction();
    Fragment fragment = null;

    switch (position) {

Answer 1

如果您想要网格视图，为什么要设置onTouchListener？

我认为问题出在这里，试着评论一段代码并测试

// Hack to disable GridView scrolling
    gridview.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return event.getAction() == MotionEvent.ACTION_MOVE;
        }
    });

GridView不会滚动
