EditText doesn't fill the whole height of the window

EditText doesn't fill the whole height of the window. Here is the code:

Why doesn't EditText fill the whole height of the window?

The width of HorizontalScrollView is the maximum width of its elements, so you can't use fill parent inside there, because the parent's width is undefined, hence it will be 0. What you are looking for - i think - is the android:scrollHorizontally attribute of EditText. Vertically it's scrollable by default (if it's size exceeds the display), so you shouldn't place it inside any ScrollViews. Simply use an EditText with fill parent dimensions, and with scrollHorizontally="true". Also make sure that the LinearLayout containing it also has fill parent height.

The parent LinearLayout property

android:layout_height="wrap_content"

must be

android:layout_height="fill_parent"

You can set the following property of the EditText view

android:layout_margin="1dip"

This is a bit of a hack but will work for now.

Setting following properties helped me to change the size:
android:minHeight="105px"
android:layout_height="115px"
android:layout_width="250px"
