ScrollView in tabhost xml - android

I want to be able to scroll within each screen in my android application. when you scroll I want the tab bar to scroll as well. My code works..However when you go to the screen with the tab bar, the tab bar is not visible..to see the tab bar you have to scroll up. Is there any way for the tab bar to be visible by default? thanks
My tab_host.xml code
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#android:id/tabhost">
<ScrollView
android:layout_height="fill_parent"
android:layout_width="fill_parent" >
<LinearLayout
android:id="#+id/LinearLayout01"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TabWidget
android:id="#android:id/tabs"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
</TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</FrameLayout>
</LinearLayout>

A ViewPager is what you need and along with a sliding tab class.
<android.support.v4.view.ViewPager
android:id="#+id/mPager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#color/white"/>

Android TabHost layout location

I have a problem placing a TabHost, as you can see in the image, the TabHost is not well placed in the screen (bottom area is below limits). I want the tabs in the middle of the screen, not on the top, the top part is occupied by a chart, this part is deliberate (Why is occupying more space in the bottom?)
The xml code is like this:
<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="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="2.0"
android:padding="5dp">
CHART IS HERE OCCUPYING A PART OF THE SCREEN
<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>
After all, the problem is that although the tab content is shown, due to the hide TabHost part, the scroll doesn't allows you to see the entire content.

Solution by OP.
This code seems to works fine when added as a view inside a LinearLayout
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1.0"
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>

Android FragmentTabHost add Horizontal scrolling

I am using FragmentTabHost for one of my project.
I have more than 5 tabs in my app.
If i used one or two tabs means the TabHost looking good.
If i add more than 5 tabs, The tabhost is shrinking and the tab text showing in a second link also.
I want to add Horizontal scroll only for my tabhost.
However we can add swipe able tab. but i don't want this. i want to swipe only the tabhost. not the tab content.
Thanks in advance.

Use this layout. It includes horizontal scroll view for tab host only.
Note: just add the horizontal scrollview to your tab host bar.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/mainlayout"
tools:context=".WebView" >
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent">
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:gravity="center"
android:background="#C0C0C0"
android:layout_height="#dimen/tab_sizes" />
</HorizontalScrollView>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"/>
</LinearLayout>
</TabHost>
</RelativeLayout>

Android TABS with fragments

I've been working on a small project that consists of a GUI with a number of tabs. I'm quite new with the concept of fragments however it seems that they're a best practice within the android tab landscape. I managed to code a simple tab app, that switches between 3 tabs.
The only issue I have is when I try placing the tabs at the bottom of the screen. When they're at the bottom, the tab widget covers the container(framelayout in this case) and so nothing happens, the screen remains the same when clicking the various tabs.
The following XML layout represents the good version( where the tabs are at the top of the screen):
<?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">
<TabHost
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"
>
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
<FrameLayout
android:id="#+android:id/realtabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
</TabHost>
</LinearLayout>
The following XML layout represents the version that isn't working, when the tabs are at the bottom of the screen:
<?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">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
/>
<FrameLayout
android:id="#+android:id/realtabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
/>
</RelativeLayout>
</TabHost>
</LinearLayout>
I changed the layour to relativelayout and added this command: android:layout_alignParentBottom="true" to the tabwidget. Does anyone have an alternative idea of how I can sort this issue? Thanks in advance.

In general using tabs at the bottom of the screen is a bad solution (see Android design guidelines).
For your solution: put TabWidget at the end of list of view. Because of drawing is a line process and fragments this your case are drowed upper TabWidget

You can use weight instead. Try this layout marking
<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
You can replace FragmentTabHost with own TabHost class. So, your tabs will be at the bottom of the screen.
Be careful with nested weights (they are bad for performance) and deeping in view hierarchy (especially for android < 4).

Is it possible to have a two level action bar?

I'm developing an Android app implementing the a tabhost, viewpager, and a top-side sliding drawer and tabs at the bottom. The application uses the android-support-v4 FragmentPagerAdapter, which can be found in the samples of the v4-support-package. A reference can be found here:
http://developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html
I can't seem to get both the Sliding Drawer and the TabHost to appear on the screen at the same time.
Here is my layout. The com.mobicartel... block is a custom sliding drawer. -------------------------------------------------------------------------------------------
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:my="http://schemas.android.com/apk/res/com.mobicartel.tabsandpager"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.mobicartel.tabsandpager.slidingdrawer.MultiDirectionSlidingDrawer
xmlns:my="http://schemas.android.com/apk/res/com.mobicartel.tabsandpager"
android:id="#+id/drawer"
my:direction="topToBottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
my:handle="#+id/handle"
my:content="#+id/content">
<include
android:id="#id/content"
layout="#layout/pen_content" />
<ImageButton
android:id="#id/handle"
android:layout_width="wrap_content"
android:layout_height="40px"
android:src="#drawable/sliding_drawer_handle_bottom" />
</com.mobicartel.tabsandpager.slidingdrawer.MultiDirectionSlidingDrawer>
<FrameLayout
android:id="#+id/tab_host_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/drawer">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:layout_marginBottom="-4dip"/>
</LinearLayout>
</TabHost>
</FrameLayout>
The content of TabHost actually isn't being displayed. Instead, the tab listener & viewpager listener control each other so they are in sync. The ViewPager is populated with fragments by a special adapter.
Any ideas?
Does anybody

I've never used TabHost with tabs at the bottom, because it is advised against (in the official Design Guidelines), however, it appears that you are using the hack found here: https://stackoverflow.com/a/2710404/377260.
I notice that your FrameLayout weight is 0, along with the height and width. Try setting them to:
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:layout_weight="1"/>
as found in the answer linked to.
