Android Tile Bitmap

I'm trying to load a bitmap in Android which I want to tile. I'm currently using the following in my view to display a bitmap:

canvas.drawBitmap(bitmap, srcRect, destRect, null)

I essentially want to use this bitmap as a background image in my app and would like to repeat the bitmap in both the X and Y directions.

I've seen the TileMode.REPEAT constant for the BitmapShader class but i am not sure if this is to be used for repeating the actual bitmap or is used for applying a filter to the bitmap.

<xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:id="@+id/MainLayout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@drawable/back"
    android:tileMode="repeat"

This worked fine for me. I did not have to create the bitmap seperately. I used the tileMode attribute in the layout.

If you want to repeat the background only vertically you can set the width of your layout to "wrap_content", whereas if you want to set the background to repeat horizontally set the height to "wrap_content". If both height and width are set to "fill_parent" then it will tile in the X and Y directions.

For example, the following code will repeat your background vertically:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:background="@drawable/news_detail_activity_bg">
</LinearLayout>
