Set text in textview very blurry

Question

I'm looking into methods of completely blurring a text in a textview. Read, completely unreadable (pixelate). The methods i'm using now are using shadows. But this seems very inefficient. Anyone who has a better solution?

Answer 1

I did not like the Paint method used in the other answers. The below code is working for me with the radius calculated depending on the font size and applying it directly on the TextView.

if (Build.VERSION.SDK_INT >= 11) {
     yourTextView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
float radius = yourTextView.getTextSize() / 3;
BlurMaskFilter filter = new BlurMaskFilter(radius, BlurMaskFilter.Blur.NORMAL);
yourTextView.getPaint().setMaskFilter(filter);

Answer 2

You should try to use canvas instead of TextView and draw a text with blur. There is a lot of method using BlurMaskFilter and you can use this like that :

paint.setMaskFilter(new BlurMaskFilter(float radius, BlurMaskFilter.Blur style));
