调整从CustomAdapter（ArrayAdapter）填充的列表视图的项目高度 <DrawerItem> ）

Question

I am stuck on this for several days now.

In my main activity, i have a listview contained in a drawerlayout(android.support.v4.widget.DrawerLayout).

I created a CustomAdapter class with custom items, and i inflate different layout depending the items i add to the arraylist through the adapter.

My problem is the following :

-The height of every rows is automatically set to the height of the most important item's height that my list contain.

This is what i would like :

-I want the height of each row to correctly wrap the content.....Meaning not leave some empty space between the bottom of the layout and the divider.

This is what i tried with no success:

-Set the layout_height of the parent layout to "wrap_content" in my custom_drawer_item.xml.

-Tried the android:minHeight in my custom_drawer_item..xml.

-In my code, i tried to use setLayoutParams(). Here is the relevant part :

 dataList = new ArrayList<>();
 mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
 mDrawerList = (ListView) findViewById(R.id.left_drawer);  

    dataList.add(new DrawerItem(true)); // adding a spinner to the list
    dataList.add(new DrawerItem("Pictures")); // adding a header to the list
    dataList.add(new DrawerItem("Options & Links")); // adding a header to the list
    dataList.add(new DrawerItem("Settings", R.drawable.ic_action_settings)); // adding a Link/Button to the list
    dataList.add(new DrawerItem("Help", R.drawable.ic_action_help)); // adding a Link/Button to the list
    dataList.add(new DrawerItem("About", R.drawable.ic_action_about)); // adding a Link/Button to the list

    CustomDrawerAdapter adapter = new CustomDrawerAdapter(this, this, R.layout.custom_drawer_item, dataList);
    mDrawerList.setAdapter(adapter);
    View item0 = getViewByPosition(0,mDrawerList);
    item0.getLayoutParams().height = 110;
    View item2 = getViewByPosition(2,mDrawerList);
    item2.getLayoutParams().height = 25;
    View item3 = getViewByPosition(3,mDrawerList);
    item3.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,25));
    adapter.notifyDataSetChanged();

 ...


     public View getViewByPosition(int pos, ListView listView) {                         
    final int firstListItemPosition = listView.getFirstVisiblePosition();
    final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;

    if (pos < firstListItemPosition || pos > lastListItemPosition ) {
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        final int childIndex = pos - firstListItemPosition;
        return listView.getChildAt(childIndex);
    }

In advance, thanks for all those who could help :) !

Constructor of "CustomDrawerAdapter" class :

public class CustomDrawerAdapter extends ArrayAdapter<DrawerItem> {

protected Context context;
protected Activity activity;
protected List<DrawerItem> drawerItemList;
protected int layoutResID;
protected String TAG = "CustomDrawerAdapter";
protected PopupWindow pWindow;

public CustomDrawerAdapter(Activity activity, Context context, int layoutResourceID, List<DrawerItem> listItems) {
    super(context, layoutResourceID, listItems);
    this.activity = activity;
    this.context = context;
    this.drawerItemList = listItems;
    this.layoutResID = layoutResourceID;
}

I just put your custom_drawer_item.xml into layout editor, and I think what's causing your heartburn is this:

    .
    .
    .
    <Spinner
        android:id="@+id/Spinner"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        .
        .
        .

With a height of match_parent , your Spinner is trying to be as big as it can.

You've also got some other problems, like a stray namespace declaration at line 9 from a cut & paste operation.
