Vertical linear layout doesn't show up, but horizontal does in java xml file

Question

I've just started Java programming in school, and my first assignment is to recreate an app I was working on using an xml layout instead of programmatically creating the elements. I have two separate linear layouts I want to appear, one is horizontal and one is vertical. All of my horizontal layouts appear fine, but whenever I try to add a vertical one, it adds but does not show up. In the emulator, I can tell it's being added because the horizontal LLs are pushed around.

Here's an example of the code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/randomButton"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight=".5"
        android:text="DERP" />
</LinearLayout>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="HIIIII" />

    <Button
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Badoop" />
</LinearLayout>

</LinearLayout>

Any suggestions? Thanks,

David

I copied your code into eclipse layout view.

You left off the closing LinearLayout element. Probably just missed it in copy paste, but if not, add it.
The "0dip" width gave me errors. When I switched to "wrap_content" it worked fine.
The Textview isn't showing because the blackground and text are both black.

Here's the textview and button:

   <TextView
    android:layout_width="wrap_content"
    android:textColor="@color/white"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="HIIIII" />

    <Button
    android:layout_width="wrap_content"
    android:textColor="@color/black"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Badoop" />

Thanks, it was actually the 0dip that was messing it up. Once I set it an actual width, it worked fine. Thank you for the response :D — DaveyDaVinci, Aug 01 '13 at 00:56
