Using NinePatch (.9.png) for making scaled Bitmaps

问题

I need to draw a Bitmap for my new Android Application. Since my content view is set to a Game-Panel class I've created. I want to display images through Bitmap. Just because its more convenient, and easier to do then anything else. From what I've gathered from researching, Nine Patch images (.9.png) are used in android to scale more properly then regular Drawable images. It also says "This can be used for scaling properly in backgrounds. For example a regular button background...". If Nine Patch images are made to scale better. Can You use a Nine Patch for making a Bitmap in a specific width and height because it would scale more properly? For example

Bitmap b = createBitmap(BitmapFactory.decodeResource(NinePatchImage), x, y, width, height);

Is this possible? Should I do it a different way? Should I create a bitmap first and then just scale the bitmap? Is this even necessary? Please help.

回答1:

Bitmap bitmap = Bitmap.createBitmap(canvasWidth, canvasHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
NinePatchDrawable drawable = (NinePatchDrawable) getResources().getDrawable(R.drawable.myDrawable);
drawable.setBounds(new Rect(x, y, width, height));
drawable.draw(canvas);
