Question

Just a quick question about how you would go about implementing this. I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added.

For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons.

Any suggestions? It can’t scroll either, it just has to dynamically fill the layout with buttons.

Thanks.

To put buttons at the bottom of a layout, do something like this to your layout:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_layout">
    <LinearLayout
        android:layout_height="wrap_content"
        android:id="@+id/button_layout"
        android:layout_alignParentBottom="true"
        android:layout_width="fill_parent"
        android:gravity="center">
        <Button
            android:id="@+id/Button01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 1"></Button>
        <Button
            android:id="@+id/Button02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 2"></Button>
        <Button
            android:id="@+id/Button03"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 3"></Button>
    </LinearLayout>
    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_above="@+id/button_layout"
        android:id="@+id/content">
        <ListView
            android:id="@+id/ListView01"
            android:layout_height="fill_parent"
            android:layout_width="fill_parent"></ListView>
    </FrameLayout>
</RelativeLayout>

To change how many buttons are shown based on the screen size, you should implement separate layouts for Multiple Screen Sizes..
