Answer 1

You should use a ShapeDrawable for the background of the component you want to add the style to.

A shape drawable is created in XML, with the following syntax (this one shows a rectangle, with the rounded corners, but there is lots you can do to customize this to look however you want). This file (named background_square.xml or whatever) should be put in your drawable folder:

 <?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="5dp" />
    <solid
        android:color="@color/primary_grey" /> 
</shape>

Then, when you want to add it to a View, you can use the following syntax in your XML:

android:background="@drawable/background_square"

You can do something like below

if you want to add rectangle simply add nested layout(say linearlayout) within your layout and set android:background="yourcolor" //you can add color using hash color values

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"    
android:padding="5dp"
android:id="@+id/layout">

<AutoCompleteTextView android:id="@+id/autocompleteCountry"
  android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/CONTRY_LABEL"
   />
<AutoCompleteTextView android:id="@+id/locationAutoCompleteFrom"
  android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/from"
    android:visibility="gone"
   />
//suppose you want to add your rectangle here
<LinearLayout 
android:id="@+id/rectangle"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"    
android:background="yourcolor"
>
</LinearLayout>

you change all the relative properties as you want say size,margins,etc
