</TableLayout>
</ScrollView>

And it looks like this when i run it in the emulator:

The top four buttons get completely hidden. Does anyone know why this is happening. Please help. Thanks in advance.

Answer 1

To fix your problem you need to change:

near:

<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:scrollbars="horizontal"
android:paddingTop="4.5dp"
android:stretchColumns="**">

from:

android:layout_gravity="center"

to

android:layout_gravity="top"

This will make your TableView be anchored by `ScrollView’ from the top and not from the center.
