LinearLayout not correctly resizing

Question

I have a LinearLayout and dynamically add three LinearLayouts to it. Each of the LinearLayouts contains a Button. After pressing one of the Buttons I wanted to display a CalendarView in the second-level LinearLayout. The View is displayed, however, it is not shown fully. I have attached a screenshot to visualize the problem: https://i.stack.imgur.com/CE9je.png

Here is the code for adding the layout:

LinearLayout.LayoutParams pLayouts = new LinearLayout.LayoutParams(
        LinearLayout.LayoutParams.MATCH_PARENT,
        LinearLayout.LayoutParams.WRAP_CONTENT
);
hllCalendar = new LinearLayout(this);
hllCalendar.setLayoutParams(pLayouts);
hllCalendar.setId(hllCalendarID);
hllCalendar.setOrientation(LinearLayout.VERTICAL);
btCalendar = {some other code}
hllCalendar.addView(btCalendar);
hllComponents.addView(hllCalendar);

And here is the code for adding the CalendarView:

LinearLayout.LayoutParams pCalendar = new LinearLayout.LayoutParams(
        LinearLayout.LayoutParams.MATCH_PARENT,
        LinearLayout.LayoutParams.WRAP_CONTENT
);
CalendarView cal = new CalendarView(this);
cal.setLayoutParams(pCalendar);
cal.setOnDateChangeListener(this);
hllCalendar.addView(cal);

Any suggestions on how I could make the calendar fully visible?

Here is the dynamically created layout for your convenience:

hllComponents pLayouts
-hllCalendar pLayouts
--btCalendar
--CalendarView pCalendar
-hllStartTime pLayouts
--btStartTime
-hllEndTime pLayouts
--btEndTime

The problem is the same as in this post.

You would need to add the LayoutParams you set onto the neighboring linear layouts — Zaid Daghestani, Jun 10 '12 at 20:04
@ZedScio The LayoutParams for Layouts is pLayouts as you can see in the first code section. — , Jun 11 '12 at 14:14
I meant the layouts surrounding hllCalendar. The most likely culprit is that hllCalendar does not have enough room to resize to wrap_content. You can test this by putting hllCalendar inside a scrollview. If you can scroll through and see the entire view, then the issue is the layouts above and/or below hllCalendar, inside hllComponents. — Zaid Daghestani, Jun 11 '12 at 14:18
@ZedScio I have added a hierarchy to my original post for you to see my current layout. Even if I remove the second and third LinearLayout the CalendarView is still not expanded, even with Udinic's help. — , Jun 11 '12 at 14:42

Try calling the requestLayout() of the parent layout.

This will post a "relayout" message on the UI's messages loop. This will calculate the new size of the layout, after the calendar was added, and thus paint it fully on the screen.

Unfortunatly that did not work out. I added these lines to the second snippet: `hllCalendar.addView(cal);hllCalendar.requestLayout(); hllComponents.requestLayout();` – Jun 11 '12 at 14:26
