Bitmap添加文字水印

private static Bitmap AddTimeWatermark(Bitmap mBitmap) {
    //获取原始图片与水印图片的宽与高
    int mBitmapWidth = mBitmap.getWidth();
    int mBitmapHeight = mBitmap.getHeight();
    Bitmap mNewBitmap = Bitmap.createBitmap(mBitmapWidth, mBitmapHeight, Bitmap.Config.ARGB_8888);
    Canvas mCanvas = new Canvas(mNewBitmap);
    //向位图中开始画入MBitmap原始图片
    mCanvas.drawBitmap(mBitmap,0,0,null);
    //添加文字
    Paint mPaint = new Paint();
    String mFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss EEEE").format(new Date());
    //String mFormat = TingUtils.getTime()+"\n"+" 纬度:"+GpsService.latitude+"  经度:"+GpsService.longitude;
    mPaint.setColor(Color.RED);
    mPaint.setTextSize(20);
    //水印的位置坐标
    mCanvas.drawText(mFormat, (mBitmapWidth * 1) / 10,(mBitmapHeight*14)/15,mPaint);
    mCanvas.save(Canvas.ALL_SAVE_FLAG);
    mCanvas.restore();

    return mNewBitmap;
}
