Question

I made an application in which a user can fill in some information in some fields. This works. But when I want to change the lay-out, I have a problem.
I want to have the fields that the user should fill in, in a colored block (background3). So, I put the code in my XML-file in a linear lay-out, but when I do this, all the fields that the user should fill in dissappear. Does anyone know what I did wrong or how I can correct this?

This is the code of my XML-file:

  <?xml version="1.0" encoding="UTF-8"?>
  <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/LinearLayout01" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:background="@drawable/background"
     android:orientation="vertical"
     android:padding="30dip">



        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent"
            android:layout_weight="1"
            android:layout_height="0dp"
            android:orientation="vertical"
           >
                     <include layout="@layout/header"/>
         </LinearLayout>

         <LinearLayout

             android:layout_weight="6"

            </LinearLayout>
        </LinearLayout>
   </LinearLayout>

Answer 1

Your layout’s height is 0dp, use wrap_content instead. So change to this:

<LinearLayout
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:layout_weight="6"
         android:background="@color/background3"
         android:orientation="vertical" >   

And you don’t have to declare the android namespace in every layout (the xmlns:android="http://schemas.android.com/apk/res/android" line)

And in your

<TextView 
            android:id="@+id/button1_label" 
            android:layout_height="fill_parent" 
            android:layout_width="wrap_content" 
            android:text="Voer hieronder je rooster in:" 
            android:textSize="24.5sp" 
            android:layout_gravity="center" 
            android:layout_marginBottom="25dip" />

there is a 25dp bottom margin, try to reduce that.

EDIT:
AND your layout_height is set to fill_parent, set it to wrap_content
