Text percentage

I put this code but the problem with the percentage gives me a warning, where shall I put them?
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="3">
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="14">
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="3">
</RelativeLayout>

try as below...
<?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"
android:weightSum="20" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="3"
android:background="#FF00FF" >
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="14"
android:background="#FFFF00" >
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="3"
android:background="#00FFFF" >
</RelativeLayout>
</LinearLayout>

relative layout position

I have a vertical linearlayout, it has inside two linearlayout with diferent elements, I would like to fix the first one to the top, and the second one centered, I'm trying it but doesn't work:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
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:background="#drawable/background_bg"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#3b5998"
>
elements
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="300dip"
android:layout_height="300dip"
android:background="#drawable/background_resto"
android:gravity="center"
>
elements
</LinearLayout>
</LinearLayout
Why is it not working? Thank you in advance

I'd advice to choose a RelativeLayout for that purpose.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/holo_blue_bright"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dip"
android:layout_alignParentTop="true"
android:background="#fff" >
</LinearLayout>
<LinearLayout
android:layout_width="300dip"
android:layout_height="300dip"
android:layout_centerInParent="true"
android:background="#android:color/holo_green_light"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
This will help you to set the exact "relative" position in relation to other views.
Best wishes,
Tim

should use RelativeLayout instead of LinearLayout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background_bg"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#3b5998"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
>
elements
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="300dip"
android:layout_height="300dip"
android:background="#drawable/background_resto"
android:layout_centerInParent="true"
>
elements
</LinearLayout>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>

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.
