manage different screen sizes

[shawn peter]

I have xml file with two buttons

<?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:padding="5dp" >

    <ImageView
        android:id="@+id/logo"
        android:layout_width="50px"
        android:layout_height="50px"
        android:layout_marginLeft="5px"
        android:layout_marginRight="20px"
        android:layout_marginTop="5px"
        android:src="@drawable/selfcare_logo" >
    </ImageView>

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:text="@+id/label"
        android:textSize="20px" >
    </TextView>

</LinearLayout>

That's what you'd use the emulator for that's part of the Android SDK. It can emulate all kinds of screen sizes.

2)Anyway if i create xml files for each layout type can you tell me how to do that?
3)If i need to handle images i found i need more density images.does more density mean larg image? elase how to create more density image from current image ?

#1: You'd use the android tool to create AVDs that you can then use with the emulator tool. In the process of doing that it will be obvious how to create AVDs emulating different screen sizes.

#2 and #3: http://developer.android.com/guide/practices/screens_support.html tells you all about it.
