Answer 1

You need to create some drawables (XML), 1 for the background (so you can add the round corners) and another 1 for the button where you will add the gradient and stroke.

EDIT: Added an example.

Result:

Layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#d4d4d4" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="4dp"
        android:layout_marginRight="4dp"
        android:layout_marginTop="15dp"
        android:background="@drawable/round_borders"
        android:orientation="vertical"
        android:paddingTop="40dp" >

        <EditText
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:paddingBottom="0dp"
            android:paddingTop="0dp"
            android:singleLine="true"
            android:text="username" />

        <EditText
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"

            android:paddingTop="0dp"
            android:singleLine="true"
            android:text="password" />

        <Button
            style="@style/OrangeButtons"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="40dp"

Answer 2

You can set layout background to white `android:background="#FFFFFFFF" or something like that. You can also have a look at shape drawables http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape , use something like solid in your xml
