我正在開發基於Tabbar導航模型的Android應用程序。 我的應用程序的一個視圖包含一個「3列」gridview，它包含10個元素，我只能看到9個元素，我無法滾動。GridView不滾動
這是我的代碼：
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) {
case 0:
fragment = new Generic_SimplePage(getResources().obtainTypedArray(R.array.entertainement_titles).getResourceId(0,-1),getResources().obtainTypedArray(R.array.entertainement_desc).getResourceId(0,-1),getResources().obtainTypedArray(R.array.entertainement_backgrounds).getResourceId(0,-1));
break;

break;
case 9 :

break;
default:
break;
}
if (fragment != null) {
ft2.replace(R.id.activity_main_content_fragment, fragment);
ft2.addToBackStack(fragment.getClass().getName());
ft2.commit();
}
