Android Emulator doesn't Scroll down

Question

I am creating a layout as follows and when I emulate it in the AVD. It doesn't Scroll down to see the conten below the fold.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_height="wrap_content"
    android:layout_width="wrap_content">

        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:textSize="20px" android:gravity="center" />

    <TextView android:text="@string/name" android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:textStyle="bold"
        android:paddingTop="20px" android:paddingLeft="10px" />


    <TableLayout android:layout_height="wrap_content"

Solution

You should wrap your layout / the part you want to scoll into a ScrollView.

e.g. you can rewrite your layout as:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">
    <LinearLayout android:orientation="vertical"
        android:layout_height="wrap_content" android:layout_width="wrap_content">
        <TextView [...]
        [...] 
    </LinearLayout>
</ScrollView>

so your root tag will be a ScrollView, and you just paste your current layout inside.
you just need to remove the namespace declaration from your LinearLayout, and declare it in the ScrollView.

The ScrollView API Docs might be helpful, and of course, Romain Guy's "ScrollView's Handy tricks".

Google will have a lot of examples for you, really. Just google "scrollview android" - you simply put a ScrollView container as the very root of your XML. Android takes care of the rest.
