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

Android: ListView and TabWidget: The ListView goes over the TabWidget

I am using the TabWidget in my android project and I have a listView and a FrameLayout in the view. The problem is that when the ListView is higher than the screen height, the Tabs are invisible because the listview goes over the tabs.
I don't know how to set the listView above the tabs.
Here is my view:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<FrameLayout
android:id="#+id/frameLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#ffffff"
android:minHeight="44dp" >
</FrameLayout>
<ListView
android:id="#+id/NewsCategorieslistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:layout_below="#+id/frameLayout"
>
</ListView>
</RelativeLayout>
And here is my tab view:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:divider="#null" >
</TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
</FrameLayout>
</RelativeLayout>
</TabHost>
Thank you very much.

I have found the solution:
<?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">
<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" />
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
</RelativeLayout>
</TabHost>

try this for your tab.xml( tab activity's layout)
<?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:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<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:padding="5dp" />
</LinearLayout>
</TabHost>

To want Tab layout set in bottom in android

How can i set Tab Layout in Bottom?
I try this property
android:gravity="bottom"
android:layout_marginBottom="-3dp"
but not any effect and give error.

Place Tab Widget to below FrameLayout like this
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tabHost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1" >
</FrameLayout>
<TabWidget android:id="#android:id/tabs"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="0" />
</LinearLayout>
</TabHost>

You have a best android Tab Layout to set that in Layout Bottom. Just use this code -
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="0dip"
android:layout_height="55dip"
android:layout_weight="1"
android:orientation="vertical"
android:background="#drawable/tab_indicator"
android:padding="5dp">
<ImageView android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:src="#drawable/icon"
/>
<TextView android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
style="?android:attr/tabWidgetStyle"
/>
And, see this answer. Hope this helps you.

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>

Text at the top of Android Tab host layout

I followed this example and got it worked.
Now I want to show a 'Welcome!!!' text just above the tabs in a Tabhost layout just like one show in figure
Here is my current layout file. But it does not show the Welcome message.
<?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:gravity="top"
android:layout_gravity="top"
android:padding="5dp">
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cc_welcome" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="Welcome"
android:gravity="top" android:padding="50dp" android:textColor="#ffffff"/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"
android:layout_gravity="bottom"
android:paddingTop="50dp">
<TabWidget
android:id="#android:id/tabs"
android:layout_alignParentTop="true"
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:padding="5dp" />
</LinearLayout>
</TabHost>

I have edited the xml file. Have a try with this :
Updated:
<?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 xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:id="#+id/welcome"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cc_welcome"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Welcome"
android:layout_centerInParent="true"
android:textColor="#ffffff"/>
</RelativeLayout>
<RelativeLayout
android:layout_below="#id/welcome"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="#android:id/tabs"
android:layout_alignParentTop="true"
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:layout_below="#android:id/tabs"/>
</RelativeLayout>
</RelativeLayout>
</TabHost>
I have updated the code. Can you please try now.
You will get a better idea about the Linear and Relative layout here
