Android Emulator doesn't Scroll down


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".
