How to make custom "button" like Facebook for Android

You can make a 3x3 table, put 3 buttons per row, and a background image as the button:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/tableLayout1"
android:layout_height="match_parent"
android:layout_width="wrap_content">

<TableRow
    android:id="@+id/tableRow1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <Button
        android:text="Button"
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon1"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon2"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon3"></Button>

</TableRow>
<TableRow
    android:id="@+id/tableRow2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <Button
        android:text="Button"
        android:id="@+id/button4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon4"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon5"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon6"></Button>
</TableRow>
<TableRow
    android:id="@+id/tableRow3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <Button
        android:text="Button"
        android:id="@+id/button7"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon7"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon8"></Button>
    <Button
        android:text="Button"
        android:id="@+id/button9"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/icon9"></Button>
</TableRow>

Change the @drawable/iconX to whatever background image you want/need.

Use three linear layout with horizontal orientation and make their parent layout with vertical orientation, like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent" android:baselineAligned="false" android:orientation="horizontal">
  <LinearLayout android:gravity="center" android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:orientation="vertical" android:layout_gravity="center_vertical" android:layout_weight="1">
      <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" >
        <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content"
            android:orientation="vertical">
            <ImageView android:background="@drawable/icon" 
                android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="left"/>
            <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"
                android:text="caption"/>
        </LinearLayout> 
            <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content"
            android:orientation="vertical" android:layout_marginLeft="20dip">
            <ImageView android:background="@drawable/icon"
