Question

I need to implement my android layout as the image below:

A – Should hold the components in the following manner

B – Should take up 75% of the screen space and should have a vertical scroll bar

My question is, how would my Android XML look like? Guys thanks in advance.

My XML is as follows:

    <?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:android1="http://schemas.android.com/apk/res/android"
    android:id="@+id/tvDate"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true" >

    <RelativeLayout
        android1:layout_width="match_parent"
        android1:layout_height="match_parent" >

        <NumberPicker

Answer 1

Now I think you should read your requirements once more yourself. You already mentioned A and B, so obviously you have to use two containers (assuming you are sure, that Fragments aren’t a better choice). Why do you use only one?

And only wrap the second container with a scrollview. If you put the ScrollView at the outer most level everything scrolls!

Use an outer LinearView and give the inner containers some weights (the left one android:layout_weight="1" and the right one android:layout_weight="3"). Weights use any remaining space and distribute it according to their percentage of the toal weight. So in this case you have 25% and 75%.

You should really read about those layouts. See the Android documentation about it or have a look at the blog Styling Android. If you cannot understand what the Eclipse layout editor generates, you won’t get desired results with it.
