Answer 1

Have you considered the Action Bar which is exactly designed for this purpose? http://developer.android.com/guide/topics/ui/actionbar.html

Answer 2

使用图像视图/ 按钮可以轻松实现底部的主控按钮, 使用动作栏是推荐的选项。您不仅可以连接到主控活动, 还可以连接到您选择的任何其他活动。引用此选项可以获取更深的洞察力。

Answer 3

您可以在 xml 版式中设置按钮/ 图像按钮/ 图像按钮/ 图像, 并在此组件上设置点击听众。您也可以使用选项菜单, 并在您应用程序的所有屏幕上给予多个选项。

Answer 4

Make a layout with a ScrollView on top, and your image-button below the scrollview.
Example:

<!-- language: lang-xml -->
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
  <ScrollView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Your Content Here"
    />
  </ScrollView>
  <LinearLayout
  android:layout_width="fill_parent"
  android:layout_height="wrap_content">
    <ImageView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_launcher"
    />
  </LinearLayout>
</LinearLayout>

It looks like this:
