I am creating one image editing application. In which I am giving facility to open camera or gallery to select picture. On selection of picture, user will navigate to other page. In other page to show picture I am using one view which implements AppCompactImageView. Now on it, I am giving facility to add text by using edittext. On click of "Done" button of soft keyboard, edittext will get disappeared and will get replaced by TextView. Now I want to drag this TextView all over the layout. But after drop operation, it's getting disappeared. Below is my code. Any help will be appreciable.
