note the image format must match the bitmap formatĭrawable background = context.getResources().getDrawable(R.drawable.background) īackground.draw(canvas) // draw the background to our bitmap Rendering text to a texture is simpler than what the Sprite Text demo make it looks like, the basic idea is to use the Canvas class to render to a Bitmap and then pass the Bitmap to an OpenGL texture: // Create an empty, mutable bitmapīitmap bitmap = Bitmap.createBitmap(256, 256, _4444) But at least, once you do that, you'll have all the flexibility and maturity they provide. There are a few around if you hunt on Google, the tricky bit is getting them integrated and running. Use an off-the-shelf/open-source library.A good way to get your feet wet but note that while it seems simple (and basic features are), it get's harder and more challenging as you add more features (texture-alignment, dealing with line-breaks, variable-width fonts etc.) - if you take this route, make it as simple as you can get away with! Probably second best choice if 2 isn't an option.

Roll-your-own text rendering code based on a sprite.This is by far the simplest and fastest, but the least flexible. Render common strings to textures, and simply draw those textures.This is slow and bad, but the most direct approach. Place a TextView over your SurfaceView.The Android SDK doesn't come with any easy way to draw text on OpenGL views.
