How might I add a watermark effect to an image in Android?

Question

I have an image with frames and I need to add a watermark effect. How might I do this?

Answer 1

You can use androidWM to add a watermark into your image, even with invisible watermarks:

add dependence:

dependencies {
  ...
  implementation 'com.huangyz0918:androidwm:0.2.3'
  ...
}

and java code:

 WatermarkText watermarkText = new WatermarkText(“Hello World”)
                    .setPositionX(0.5) 
                    .setPositionY(0.5) 
                    .setTextAlpha(100) 
                    .setTextColor(Color.WHITE) 
                    .setTextFont(R.font.champagne) 
                    .setTextShadow(0.1f, 5, 5, Color.BLUE); 

 WatermarkBuilder.create(this, backgroundBitmap) 
                    .loadWatermarkText(watermarkText) 
                    .getWatermark() 
                    .setToImageView(backgroundView); 

You can easily add an image type watermark or a text watermark like this, and the library size is smaller than 30Kb.
