类似的东西？将位图绘制到画布并绘制文本然后保存？

drawingCache = Bitmap.createBitmap(300, 400, Bitmap.Config.ARGB_8888);

Canvas canvas = new Canvas(drawingCache);
Paint paint = new Paint();

// Draw your bitmap to the canvas
canvas.drawBitmap(bitmap, 0, 0, paint);

Paint watermarkPaint = new Paint();
watermarkPaint.setColor(Color.WHITE);
watermarkPaint.setAlpha(150);
watermarkPaint.setTextSize(30);
watermarkPaint.setTextAlign(Paint.Align.LEFT);
watermarkPaint.setFlags(Paint.ANTI_ALIAS_FLAG);

canvas.drawText("Watermark", 100, 100, watermarkPaint);
