Moving an ImageView on Android

Moving an ImageView on Android

I'm trying to write an app to play Snakes and Ladders (this is the first
app I've ever written, and i'm just doing it for fun...not for a course or
commercial purposes or anything).
So my problem is, I want to move my ImageView of a player token from one
square on the board to another square. I don't know how to do two things:
How can I place the imageview of the token on top of the board imageview
in the layout?
How can I go about moving the token imageview itself by a certain % of the
size of the board imageview? Is this possible or am I supposed to do this
some other way?
I have classes written for the player, board and squares that all work
fine. I just need to know what to do with the player's token. (I have
tested it by displaying a toast message saying the player location every
time I roll the die).
Here is the xml code for the layout:
<?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:layout_gravity="center"
android:background="@drawable/stripes_background"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_gravity="center"
android:layout_marginTop="0dp"
android:layout_weight="0.1"
android:orientation="horizontal" >
<Button
android:id="@+id/toGameListButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1.00"
android:background="@drawable/alternate_button_background"
android:text="Quit"
android:textColor="#FFFFFF"
android:textSize="17sp" />
<Button
android:id="@+id/restartButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1.00"
android:background="@drawable/alternate_button_background"
android:text="Restart"
android:textColor="#FFFFFF"
android:textSize="17sp" />
</LinearLayout>
<TextView
android:id="@+id/textViewTurn"
android:layout_width="match_parent"
android:layout_height="0dip"
android:gravity="center"
android:layout_weight="0.1"
android:text="TextView set to Player&apos;s turn"
android:textColor="#FF9900"
android:textSize="19sp"
android:textStyle="bold" />
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="0dip"
android:layout_weight="0.7" >
<ImageView
android:id="@+id/game_board"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:contentDescription="Board"
android:src="@drawable/snakes_and_ladders_raw_board" />
<ImageView
android:id="@+id/green_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</FrameLayout>
<Button
android:id="@+id/rollButton"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_marginTop="10dp"
android:layout_weight="0.1"
android:background="@drawable/alternate_button_background"
android:text="Roll!"
android:textColor="#FFFFFF"
android:textSize="19sp" />
</LinearLayout>
Any advice is greatly appreciated. Let me know if I'm supposed to be more
specific in my problem or anything.
