you can't use layout_weight in ScrollView because it depend on the height of the child layout and layout_weight too depend on the height of the outside layout and that's contradiction, so you can use custom layout_height to every child .
I know the answer is late but i hope it help someone else .

The android:layout_weight attribute is used in conjunction with the android:weightSum attribute. Your children layout_weights must sum to the weightSum of their parent layout.
You use layout_weight many times in your xml code without declaring a weightSum. Without android:weightSum, android:layout_weights will have no effect. For instance, if you want two views within a parent LinearLayout to span evenly, you can do something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100">
<EditText
android:id="#+id/my_edit_text"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50"
android:hint="type something">
<Button
android:id="#+id/my_button"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50"
android:text="a button">
</LinearLayout>
Note that your child views' layout_heights will need to be set to "0dp" for vertical LinearLayout orientation. For a horizontal orientation, you'd set the child views' layout_widths to "0dp".
For another example, see the accepted answer at https://stackoverflow.com/a/7452788/4138919
I also notice that you mix floating point values with non-floating point values for layout_weights. Consider sticking to one or the other for readability purposes.

For changing Edittext height you should also prefer to use attributes like maxHeight, minHeight, maxLines, inputTypes, and textAppreance attributes,
This below example might help you :

Can't get to the bottom of the content with my scrollview

I have my xml file. It is a RelativeLayout with a ScrollView and inside the ScrollView I have LinearLayout and many more. The problem is that I can't reach the end of the view, as you can see it end with a "Sign Up" button... But my view is cut by the scroll and I can just see the middle of the button, the other middle is off screen.
So, any suggestions for how can I fix this? How can I work with the ScrollView so it wraps all of my content...

scrollable layout not working

I'm a beginner in android. I'm creating a example phonebook using eclipse. i have few edit texts and a set off buttons in my layout.but when I run the project I can't see the buttons in the bottom of the layout, so I enclosed my main linear layout in a Scrollview. but after linear layout has become much bigger in height. i tried to resize it in the xml file but it is not working right after resizing the layout it automatically resizes in to the previous size. here's my code if anyone can help me.little help is highly appreciated.

You need to set ScrollView layoutWeight to 1 and its height to 0. This will ensure that your scrollview will take only remaining space on screen. Here is example of my app:

It shows scrollView and two buttons bellow it. I am not exactly sure what you want to do but as far as I can see you are doint it wrong. ScrollView can take only one child element but you have set scrollview as your main parent but then you put more child inside it.
Also you are doing another mistake. You dont need to use linear layouts (in most cases) if they have only one child. It is bad for performance.

Change the value of the attribute layout_height to match_parent so that the ScrollView take up the whole screen and hence enable scrolling. The correct code is
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

You could try changing
android:layout_height="466dp"
to
android:layout_height="wrap_content"
or
android:layout_height="match_parent"
