I am pretty new into android development and have a couple questions I'm sure you guys can answer pretty quickly but have so far not been able to figure out. How do I have a set background in a live wallpaper besides just creating something from canvas, I have it already loaded in the hdpi I just need to figure out how to call it. Also, is it possible to have something appear enlarge a little bit in the center of the screen then fall off the screen? I'm trying to create a time lapse of a tree where it goes through all the weather changes. Any sites you could link me too or answers you would have would be greatly appreciated. Thanks for anything you guys are able to do.
Can you be more specific? When you say background are you talking about an image file you've added as a drawable?
If you use the drawBitmap method you can draw images anywhere on a canvas.
This is roughly how I do it on my Live Wallpapers.
Code:
Bitmap background = BitmapFactory.decodeResource(getResources(), R.drawable.background);
c.drawBitmap(background, 0, 0, null);
That will draw the bitmap at the upper left most position on your canvas.
If you want your live wallpaper to slide left and right as you swipe between home screens you need to adjust the x position based on the offset. Look at the cube live wallpaper source code for more information on how to get the offset value.
What I have is a picture loaded in the hdpi file that I want to use as my background, the thing with the cube is it shows you how to draw a picture but not add one into it. I want to load in the photo and then have objects enlarge and drop down around the center of this picture. The design I'm going for is a time lapse of a tree. I was told surfaceView can set your background but I'm not sure if that's the case or not. Thanks for the reply though I appreciate it.

Click to expand...
Click to collapse
It works exactly the same but instead of using c.drawLine() you use c.drawBitmap()
That makes a lot of sense thanks, and for the leaves falling would you just set the coordinates to somewhere in the middle then? Also, is there a way to have an image change color mid-screen so it looks like fall is hitting? Thanks for all your help again though.
hello everybody.
can someone please make a Phone.apk with full caller id image ?
i mean - when someone calling me, his picture is shown half clear-half black, until i answer the call .
i want the picture to be all-clear, in a square shape, so the whole image will be shown up, and not just the upper-half.
like the samasung Galaxy S3 has.
i don't want to use apps like "Big Caller ID" cause they shows full-screen image, and its ugly.
hope someone will be able to help me with that.
thanks!
sorry if i posted in wrong place but i cant see where else that post can go

Hello
I am on a Lollipop standard rom and I have root.
Is there a way to make the green colour in the caller id screen see trough or something?
Why the heck did they put that big line there? The faces of people calling gets hidden behind it!
Hi,
When a contact calls me (without the S View cover) I get a big photo in the screen (not fullscreen, but bigger then the standard "round picture").
Can this be displayed in the S View screen as well? Because here I have the little rounded pictures when someone calls me.
Thanks for answering
