drawable

问题 I'm trying to implement a custom drawable which should have the shape of a speechbubble. Therefore I use two paths, one draws the rect and the other should draw the triangle for the bubble. My class looks like the following: public class SpeechBubbleView extends Drawable { private Paint mBubblePaint; private Paint mBubblePaint2; private Path mRectPath; private Path mBubblePath; public SpeechBubbleView() { } public void initPaint() { mBubblePaint = new Paint(Paint.ANTI_ALIAS_FLAG);

问题 I'm making a simple whack-a-mole game as my first mini-project for android. I'm not sure how to go about this. I know the basics of setting everything up and such but I'm not sure how to animate the moles and make it so that when the mole is in the up position it can be tapped and a point will be counted. I know I can do an image button and have a counter go up(counter++) but I need to be able to switch frames from the mole in the hole to the mole in the up position. I've been told to use a

问题 I used the following code to retrieve an image from a url and display it within an activity. InputStream is = (InputStream) new URL(url[0]).getContent(); Drawable d = Drawable.createFromStream(is, "imagename"); ImageView... Now I want to save this image (Drawable d) locally when a user clicks a button so I can display it again in another activity (along with a few other tasks). I'd like to store it within the app folder itself rather than on the SD card. How would I do this? Thanks! Shannon

问题 I'm trying to rotate an overlay drawable to represent an overlay item in Android. I use this: Bitmap bmpOriginal = BitmapFactory.decodeResource(this.getResources(), R.drawable.map_pin); Bitmap targetBitmap = Bitmap.createBitmap((bmpOriginal.getWidth()), (bmpOriginal.getHeight()), Bitmap.Config.ARGB_8888); Matrix matrix = new Matrix(); matrix.setRotate((float) lock.getDirection(),(float) (bmpOriginal.getWidth()/2), (float)(bmpOriginal.getHeight()/2)); Canvas tempCanvas = new Canvas
