Three ways to implement background tiling in Android

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pic);  
//bitmap = Bitmap.createBitmap(100, 20, Config.ARGB_8888);  
BitmapDrawable drawable = new BitmapDrawable(bitmap);  
drawable.setTileModeXY(TileMode.REPEAT , TileMode.REPEAT );  
drawable.setDither(true);  
view.setBackgroundDrawable(drawable);

<bitmap xmlns:android="http://schemas.android.com/apk/res/android"   
    android:src="@drawable/img"  
　　  android:tileMode="repeat" />

public static Bitmap createRepeater(int width, Bitmap src){  
　　int count = (width + src.getWidth() - 1) / src.getWidth();  
　　Bitmap bitmap = Bitmap.createBitmap(width, src.getHeight(), Config.ARGB_8888);  
　　Canvas canvas = new Canvas(bitmap);  

　　for(int idx = 0; idx < count; ++ idx){  
　　  canvas.drawBitmap(src, idx * src.getWidth(), 0, null);  
　　}  

　　return bitmap;  
}
