I am totally new to Android studio and Java. I am building project. I have made two main activities with buttons. In second activity I have 14 buttons. My goal is to click one of the buttons, which will start new activity with big image which I can pinch zoom. I found this subsampling-scale-image-view
How can I apply this custom imageview with my existing project? Can someone please give me step by step solution? I have tried to import it as module, but I can not run new activity for button as it is described in setup. I am maybe doing something wrong, but I can not figure out how to do it. I spent hours on it.
