Stop Android webview covering tabwidget

I have a tabwidget placed at the bottom of the screen with a webview above it. When the content of the webpage the webview loads is larger than the screen, the webview expands to conver the tabwidget - because the layout_height is set to wrap_content in the webview and the scrollview it sits in.
I'd like the scrollview to size to the available screen space.
My xml is as follows:
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="0dp" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="-4dp"
android:gravity="top" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true" >
<ScrollView
android:id="#+id/scroll1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="none"
tools:ignore="UselessParent" >
<WebView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="bottom"/>
</ScrollView>
</FrameLayout>
</RelativeLayout>
I've put in a set height for the scrollview but as would be expected it is only accurate to a certain device(s), not universal.
Any assistance would be appreciated.

use this xml , it will solve your problem :
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="0dp" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<ScrollView
android:id="#+id/scroll1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="none"
tools:ignore="UselessParent" >
<WebView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="bottom" />
</ScrollView>
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</TabHost>

This layout or it's parent layout is possibly useless (AnDroid)

I want to use more than one CheckBox in each tab, but only one box shows up in the tab even though I have three under LinearLayout.
I set the ID for each checkbox also.
Here is the code that is being used.
main.Xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/widget43"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<CheckBox
android:id="#+id/root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Tortillas" />
<CheckBox
android:id="#+id/root1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Tortillas1" />
<CheckBox
android:id="#+id/roo2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Tortillas2" />
</LinearLayout>
</FrameLayout>
</TabHost>

In addition to #Barak, you are missing a linear layout after TabHost
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/widget43"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<CheckBox
android:id="#+id/root"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Tortillas" />
<CheckBox
android:id="#+id/root1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Tortillas1" />
<CheckBox
android:id="#+id/roo2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Tortillas2" />
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>

I think you need to change the CheckBox width and height to "wrap_content" instead of "fill_parent". The first one fills the parent and there's nothing left for the rest.
EDIT
Change the heightof the LinearLayout to wrap_content as well (looking at some of my own, that's how I have them set up).

Align ad layout at top

I'm trying to align an ad layout at the top of a Tab Layout and am not having much luck. It seems to be stuck aligning at the bottom. I've configured the Tab Layout so the tabs are at the bottom of the screen:
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:id="#+id/adLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
</RelativeLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dp"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:padding="0dp"
/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="23dp"
android:background="#drawable/tab_bg_selector"
android:layout_weight="0"
/>
</LinearLayout>
</TabHost>
Update:
I fix it, I forgot I was setting the alignment in the code, like this:
final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
Once I changed ALIGN_PARENT_BOTTOM to ALIGN_PARENT_TOP, it worked.

I can't understand your layout structure but what I understood is that you want to display ads at the top of the screen and for that I modify your code
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout android:id="#+id/adLayout"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_alignParentTop="true">
</RelativeLayout>
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="#drawable/tab_bg_selector"
android:layout_alignParentBottom="true" android:layout_weight="0" />
<FrameLayout android:id="#android:id/tabcontent"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1" android:padding="0dp"
android:layout_below="#id/adLayout" android:layout_above="#android:id/tabs"/>
</RelativeLayout>
</TabHost>

HorizonatalScrollView on TabWidged "steals" space

I have an TabActivity with custom TabWidgets at the bottom. I want to be able to add more than 5 Tabs. Unlike the MenuBar, which adds a "more" button dynamically, Tabs are just resized and look horribly. So my first attempt was to wrap my TabWidgets into a HorizontalScrollView. The problem is, that I have a ListView as TabContent and its last item seems to be hidden behind my TabWidgets.
This is the Layout for my TabView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_linlay_parent"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:id="#+id/main_tablinear"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_above="#android:id/tabs"/>
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none"
android:layout_alignParentBottom="true">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"/>
</HorizontalScrollView>
</RelativeLayout>
</TabHost>
</LinearLayout>
am I doing something wrong in my Layout? Are there better ways to apply more than 4 Tabs? While I can see 4 Tabs good with my Nexus-S, I'm thinking they are already ugly on a Wildfire. Any idea appreciated

Try this. It worked for me:
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<TabHost android:layout_weight="1" android:id="#android:id/tabhost"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical">
<HorizontalScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout android:layout_height="fill_parent"
android:orientation="horizontal" android:layout_width="fill_parent">
<TabWidget android:layout_height="wrap_content"
android:id="#android:id/tabs" android:isScrollContainer="true"
android:layout_width="fill_parent" android:scrollbars="horizontal"></TabWidget>
</LinearLayout>
</HorizontalScrollView>
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#android:id/tabcontent">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/tab1"></LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/tab2"></LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/tab3"></LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/tab4"></LinearLayout>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/tab5"></LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost></LinearLayout>

I solved my problem myself! I think it can be helpful for other users to see the soltution:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_linlay_parent"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:id="#+id/main_tablinear"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_above="#android:id/tabs"
android:layout_marginBottom="50dip"/>
<!-- note: margin bottom 50 dip above:
its exactly the size of my custom TabWidget -->
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none"
android:layout_alignParentBottom="true">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"/>
</HorizontalScrollView>
</RelativeLayout>
</TabHost>
</LinearLayout>

Android - Add button after tabhost not showing in every tab

So i wanted to have a bottom button so that it shows in all tabs, but i cant seem to make it available at the bottom of every tab screen. I only have the first tab filled with edit text elements and spinners. But the button doesnt show even after setting a scrollview since all elements take more than the screen size. Heres the xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TabHost
android:id="#+id/personalfiletab"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="56dp">
<ScrollView android:id="#+id/ScrollView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout
android:id="#+id/pessoal_tab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<include android:id="#+id/first" layout="#layout/ecra_editpersonalfile_infoform" />
</TableLayout>
<TableLayout android:id="#+id/morada__contacto_tab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<include android:id="#+id/first" layout="#layout/ecra_editpersonalfile_moradacontactoform" />
</TableLayout>
<TableLayout
android:id="#+id/profissional_tab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<include android:id="#+id/first" layout="#layout/ecra_editpersonalfile_infoproform" />
</TableLayout>
<TableLayout
android:id="#+id/documentacao_tab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<include android:id="#+id/first" layout="#layout/ecra_editpersonalfile_documentacaoform" />
</TableLayout>
</LinearLayout>
</ScrollView>
</FrameLayout>
</LinearLayout>
</TabHost>
<Button
android:text="submit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/submitprofileButton">
</Button>
</LinearLayout>
But the button doesnt show at the bottom of the screen in every tab...
