Question

I have a back.png file which I need to

1. assign to a variable and convert to bitmap
2. apply a hue function to it
3. and put it back

a = BitmapFactory.decodeResource(this.getResources(),R.drawable.back);

b = Hue(a);

View c = (View)findViewById(R.drawable.back);

///need to make View C = Bitmap B ... but how?

Here’s my code so far, everything works, only I don’t know how to assign my bitmap “b” back to view “c” … any ideas?

Thanks!

backrepeat.xml

<?xml version="1.0" encoding="utf-8"?>

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

---

AbsoluteLayout al = (AbsoluteLayout)findViewById(R.id.setLay);
Drawable dback = al.getBackground();
a = ((BitmapDrawable)dback).getBitmap();
//b = Hue(a);
d =new BitmapDrawable(a);
al.setBackgroundDrawable(d);

Edit, tired that one, but converting from a drawable to a bitmap and then back again makes it loos is tileing. I just get one bitmap stretched all over the screen…

Answer 1

wat r u doing…R.drawable.back must be a png file it cannot be a view….

i mean view u must be using would be the main view like relative,absoulte,frame etc. or an imageview….u had to have one of such views

d=new BitmapDrawable(bm);
rl.setBackgroundDrawable(d);

where rl is my relative layout

rl=(RelativeLayout)findViewById(R.id.brl);
