    android:smallScreens="true"
    android:normalScreens="true"
    android:largeScreens="true"
    android:xlargeScreens="true"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@layout/bg_repeat" >

<RelativeLayout
    android:id="@+id/bg_header"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="top"
    android:background="@drawable/bg_header"
    android:padding="0dip">
    <ImageView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:src="@drawable/text_header" />
</RelativeLayout>

<ListView
    android:id = "@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:divider="@null"
    android:dividerHeight="2.5dp"
    android:layout_marginTop="10dp"
    android:layout_marginBottom="10dp"
    android:cacheColorHint="@android:color/transparent"
    android:listSelector="@android:color/transparent"
    />
</LinearLayout>

and this is row xml for xhdpi:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout
xmlns:android = "http://schemas.android.com/apk/res/android"
xmlns:foo="http://schemas.android.com/apk/res/test"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingRight="20dp"
android:paddingLeft="20dp">

<LinearLayout
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/menu_selector">

<test.TextViewPlus
    android:id="@+id/menutext"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:textColor="#3D1E00"

Answer 1

main xml code:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <RelativeLayout
        android:id="@+id/bg_header"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:background="@drawable/bg_header">
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/text_header" />
    </RelativeLayout>
    <ListView
        android:id = "@+id/mainlist"
        style="@style/ListView"
        android:dividerHeight="2.5dp"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp"/>
</LinearLayout>
</merge>

android:paddingLeft="20dp">
<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/menu_selector"
    android:gravity="center">

    <pak.TextViewPlus
        android:id="@+id/menutext"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
