View 3 Replies View RelatedAndroid :: Draw On Bitmap
Nov 11, 2010I'm trying to figure out how to draw on a bitmap in android, and keep a copy of these changed bitmaps for an undo function.
Bitmap b = ...
Paint p = new Paint();
canvas.drawBitmap(b, new Matrix(), null);
canvas.drawCircle(0,0,20,20);
//does Bitmap b have the circle drawn on it next time?
Or how do I get the bitmap after its been drawn on with the canvas(I want to preserve a stack of bitmaps with the changes applied by canvas drawing)? Maybe I'm going about this entirely wrong.

View 6 Replies View RelatedAndroid :: IOS / GPS Battery Draw?
Aug 4, 2010I'm investigating the possiblity of writing an app for Android/iOS4/both that would use GPS in the background. I found the "Receiving Location Events in the Background" section of the iphone developer documentation, which recommends that I only register for "significant location change" events. I'm not aware of any such capability in the Android SDK, but it still seems like a good idea to do it this way if I can (so as not to drain the battery). My question is this: has anyone done any sort of benchmarking for this on and iPhone/Android phone? So far, I've seen a lot posts/documentation saying that listening for GPS events in the background is a VERY BAD THING and I should AVOID IT AT ALL COSTS, but I haven't been able to find any numbers for just how much power a background application listening on GPS changes would drain (i.e. % battery drain per time app is running in the background).
This information might be helpful for me (and possibly others too) because I might be able to poll less frequently or even register/unregister my GPS listener based on power drain. Essentially, I could try to put a ceiling on how much battery life my app could drain while in the background.
Android :: Draw From Old Canvas
Oct 28, 2010I'm making an App that needs to be able to draw new graphics on top of the last set.
This is my current onDraw() method -
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
if(points.size() > 0) {
//do some stuff here - this is all working ok
canvas.drawLine(p1.x, p1.y, p2.x, p2.y, linePaint);
}
}
Basically, I need to draw the new graphics as a layer on top of the last, so what I'm looking for is a way to carry the image of the last canvas to the current. I have tried to figure it out myself using the canvas.setBitmap() method but it acts very funny.

Android :: Getting My Views To Re-draw?
Oct 3, 2010I have a set of views that are populated with data from an online database. The context menu has a "refresh" choice that re-reads the online database and updates some attributes of the views, like setText and setChecked for some buttons. After the various setTexts and such, I invalidate the Views. However, they are not immediately redrawn. In fact, they don't get redrawn at all unless something like a rotation happens to cause a redraw of the screen. How can I initiate an immediate redraw after the refresh is complete?

Oct 13, 2010I am wondering what the best way to render a tournament draw (scrollable) might be for android. Since I am new to this, I was not sure whether to invest time creating a ListView sort of thing or dynamically building html pages and rendering them with WebView. Or I could plop everything into a regular scrollable text view, perhaps. The main requirement is that I would need the tournament participants to be individually clickable.

View 4 Replies View RelatedAndroid :: Draw GLSurfaceView To A Bitmap
Nov 4, 2009I have an application that uses GLSurfaceView to draw OpenGL ES graphics. This is all working (mostly) how I would expect.
Now, I would like to implement a screenshot feature. For normal views, it seems that the standard practice is to create a new Canvas with a Bitmap and then draw to that Canvas using View.onDraw(Canvas).
I've tried using SurfaceView.draw(Canvas) in a similar fashion, but it always results in a blank (black) image.
I've also tried using the drawing cache with the exact same result.
