Question

I am currently having problems with a scrollable view within a tab on an android layout. The view scrolls past underneath the tabs without a scrollable view implemented in the tab layout as shown below.

When I place a scrollable view within the tabbed layout it shows a small scrollable view that appears buggy and unusable. Shown below.

The code for the tab host is below

<?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_height="fill_parent"
    android:layout_width="fill_parent">
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true"
        android:padding="5dp" />
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_alignParentBottom="true"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />        
</RelativeLayout>
</TabHost>

and this is the code for the tab with the scroll view implemented

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/todayScroll" 
android:layout_height="wrap_content"
android:layout_width="fill_parent" >

<LinearLayout 
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"      
    android:orientation="vertical" >

            <ExpandableListView
                android:id="@+id/ExpList"
                android:layout_height="match_parent"
                android:layout_width="match_parent"
                android:groupIndicator="@null" />   

</LinearLayout>
</ScrollView>

Any ideas of how to get the content to scroll correctly and not get in the way of the tabs would be greatly appreciated 🙂 Thanks.

I’ve tried a fair few times but it’s starting to get very frustrating.

EDIT:
Here is the TabHostActivity file.

public class TabbedMainActivity extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tab_main);

    TabHost tabHost = getTabHost();

    // Tab for todays meals
    TabSpec todaysSpec = tabHost.newTabSpec("Todays");
    //you could set icon here as well as title
    todaysSpec.setIndicator("Todays");
    Intent todaysIntent = new Intent(this, TodaysMealsActivity.class);
    todaysSpec.setContent(todaysIntent);

    // Tab for future meals
    TabSpec futureSpec = tabHost.newTabSpec("Future");
    futureSpec.setIndicator("Future");
    Intent futureIntent = new Intent(this, FutureMealsActivity.class);
    futureSpec.setContent(futureIntent);

    // Tab for comments
    TabSpec commentsSpec = tabHost.newTabSpec("Comments");
    commentsSpec.setIndicator("Feedback");
    Intent commentsIntent = new Intent(this, CommentsActivity.class);
    commentsSpec.setContent(commentsIntent);

    // Adding all TabSpec to TabHost
    tabHost.addTab(todaysSpec); // Adding todays tab
    tabHost.addTab(futureSpec); // Adding future tab
    tabHost.addTab(commentsSpec); // Adding comments tab
}
}

Cheers,

Edit from comments: An alternate solution (the one used by the OP) was found here.

Use android:layout_height="fill_parent" on your ScrollView. (Or, since fill_parent is deprecated, use android:layout_height="match_parent".)

First, remove your ScrollView, and replace your RelativeLayout with this:

<RelativeLayout
    android:layout_height="fill_parent"
    android:layout_width="fill_parent">

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_above="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp" />

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_alignParentBottom="true"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</RelativeLayout>
