Android: Tabs at the BOTTOM

Question

Hi,
I've seen some chatter about this, but nothing definite. Is there a way to put the tabs in a TabWidget to the bottom of the screen? If so, how?

I've tried the following, but didn't work:

a) setting the tabwidget below the framelayout
b) setting the tabwidget's gravity to "bottom"

Thanks! llappall

Answer 1

Is there any solution for setting the tabs at the bottom?

Answer 2

This may not be exactly what you're looking for (it's not an "easy" solution to send your Tabs to the bottom of the screen) but is nevertheless an interesting alternative solution I would like to flag to you :

ScrollableTabHost is designed to behave like TabHost, but with an additional scrollview to fit more items ...

maybe digging into this open-source project you'll find an answer to your question. If I see anything easier I'll come back to you.

Yes, see: http://www.anddev.org/viewtopic.php?p=21932, but he used xml layouts, not activities to create new tab, so put his xml code (set paddingTop for FrameLayout - 0px) and then write the code:

public class SomeActivity extends ActivityGroup {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

    TabHost tab_host = (TabHost) findViewById(R.id.edit_item_tab_host); 

    tab_host.setup(this.getLocalActivityManager());

    TabSpec ts1 = tab_host.newTabSpec("TAB_DATE"); 
    ts1.setIndicator("tab1"); 
    ts1.setContent(new Intent(this, Registration.class)); 
    tab_host.addTab(ts1); 

    TabSpec ts2 = tab_host.newTabSpec("TAB_GEO"); 
    ts2.setIndicator("tab2"); 
    ts2.setContent(new Intent(this, Login.class)); 
    tab_host.addTab(ts2); 

    TabSpec ts3 = tab_host.newTabSpec("TAB_TEXT"); 
    ts3.setIndicator("tab3"); 
    ts3.setContent(new Intent(this, Registration.class)); 
    tab_host.addTab(ts3); 

    tab_host.setCurrentTab(0);      


}

}

Here's the simplest, most robust, and scalable solution to get tabs on the bottom of the screen.

1. In your vertical LinearLayout, put the FrameLayout above the TabWidget
2. Set *layout_width* to *wrap_content* on both FrameLayout and TabWidget
3. Set FrameLayout's *android:layout_weight="1"*
4. Set TabWidget's *android:layout_weight="0"* (0 is default, but for emphasis, readability, etc)

Full 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">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dp"
            android:layout_weight="1"/>

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"/>

    </LinearLayout>

</TabHost>

I haven't yet figured out how to move that grey underlining divider below the tabs above them, however.

Try it ;) Just watch the content of the FrameLayout(@id/tabcontent), because I don't know how it will handle in case of scrolling... In my case it works because I used ListView as the content of my tabs. :) Hope it helps.

<?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>
