Making Overlaid image transparent on touch in Android ?
- by Andhravaala
Hi All, I need help on making the touched areas of bitmap image transparent(seems like erasing) while I am moving my finger on that image.
I am having a PNG file with Alpha channel in it. I want to turn the touched pixels to transparent so that, the user can feel that he is actually erasing it.
For this I am using frame layout to load 2 layers. Down layer is for content and upper layer is an Imageview for erasing. I need erase the upper layer when user touch and move his finger on it.
I am not getting how to make it transparent. can anyone please help me in this. If possible please direct me to any sample code, as I am very new to this image processing.
Thanks in advance.
