此（未经测试的）代码应使您走上正确的道路。
void foo(final String text) throws IOException{ final Paint textPaint = new Paint() { { setColor(Color.WHITE); setTextAlign(Paint.Align.LEFT); setTextSize(20f); setAntiAlias(true); } }; final Rect bounds = new Rect(); textPaint.getTextBounds(text, 0, text.length(), bounds); final Bitmap bmp = Bitmap.createBitmap(bounds.width(), bounds.height(), Bitmap.Config.RGB_565); //use ARGB_8888 for better quality final Canvas canvas = new Canvas(bmp); canvas.drawText(text, 0, 20f, textPaint); FileOutputStream stream = new FileOutputStream(...); //create your FileOutputStream here bmp.compress(CompressFormat.PNG, 85, stream); bmp.recycle(); stream.close();}
