Android ListView set Number of items to show


Android ListView set Number of items to show

I wish this help you I think the amount of Items shown in the Listview depends on the size that is available for the list. I would try a layout that limits the size of the list. It could be possible that such a detailed layout is not possible very easily, a different screen size could show more items etc.

Android - ListView within a ListView does not expand to show all items

I wish this help you I believe you will have much better luck by using an ExpandableListView and an ExpandableListAdapter instead of this complicated layout.
You can then expand every group by iterating through them and calling expandGroup(int groupPos)

this will help Turns out that using the Holder created by Guice in the constructor was the problem. If I use a Provider, then the list behaves as expected
code :
public class ListViewHolder extends ViewHolder {

    @Override
    public View getView(View view) {
        Holder holder;

        if (view == null) {
            view = LayoutInflater.from(contextProvider.get()).inflate(R.layout.entry, null);
            // getHolder looks like this:
            // @Inject
            // private Provider<Holder> holderProvider;
            // public Holder getHolder() {
            //     holderProvider.get();
            // }
            holder = getHolder();

            holder.text = (TextView) view.findViewById(R.id.textView1);

            view.setTag(viewStructure);
        } else {
            holder = (DualTextViewStructure) view.getTag();
        }

        holder.text.setText(/* Date */);

        return view;
    }
}

I hope this helps you . In your custom array adapter, you can do something like this:
CustomArrayAdapter.java
code :
public interface MenuListener {
    void setMenuItemVisible(boolean state);
}

private MenuListener mListener;
private Item[] mListItems; // The list of items that your adapter handles

public void setMenuListener(MenuListener listener) {
    mListener = listener;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ListView listview = convertView.findViewById(R.id.yourListViewId);
    if (mListItems.size() > 0) {
        mListener.setMenuItemVisible(true);
    } else {
        mListener.setMenuItemVisible(false);
    }

}
public class Activity implements CustomArrayAdapter.MenuListener {

    private MenuItem menuItem; // The menu item that you wanna show/hide

    ....

    @Override
    public void onCreate(Bundle savedInstanceState) {

        CustomArrayAdapter adapter = new CustomArrayAdapter(params...);
        adapter.setMenuListener(this);
        // Set listView adapter
    }

    @Override 
    public boolean onCreateOptionsMenu(Menu menu)
    { 
        menuItem = menu.findItem(R.id.menuItemId); // Save the menu item that you want to show/hide later
        ...
    }

    @Override
    public void setMenuItemVisible(boolean state) {
        menuItem.setVisible(state);
    }
}

Hope this helps Ok, I think I've cracked it! I changed the ItemsPanelTemplate to a UniformGrid panel that I got from here . Its a UWP version for the one that WPF has, and as such you can set the number of rows and columns. for my example above, Rows = 7 , Columns = 1.
All I changed after that was to add the following additional Setter in the ItemContainerStyle:
code :
<Setter Property="VerticalContentAlignment" Value="Stretch"/>
