问题 I'm an italian student developing an Android application with the latest version of Android Studio and with Android API 26 (Android Oreo). The application is very simple: 1. Main activity, "MySchoolSyllabus": it shows a list of school subjects, represented by images placed in the "res" project's folder. 2. Second activity, "Materia" (it means "subject"): once the user clicks on a subject image, this activity needs to be opened, showing another list of images, representing that subject's

问题 I have an ImageView and VideoView on my screen. My Activity is always in a portrait mode (and i can't rotate it because of another elements).

问题 I am loading gif image in Imageview with container recyclerview. Currently the recyclerview has only 1 gif and other are bitmaps.

问题 Ok so I have a list view with a custom list view adapter, and each list item has an "icon". when I click the list item, I am easily able to get all the text field names such as name address etc. I have their icon in an image view (obviously every icon is in the same id because it is getting reused in the listview). my question is how can i get the r.drawable.resource (ie pic1) when i click the list item . and pass it to my next intent (I know how to use bundle extras). I have been searching

问题 I know the basics on how to take a picture and set it to ImageView. photo = (Bitmap) data.getExtras().get("data"); imageView.setImageBitmap(photo); I want to do a little more than that.

问题 I have an object which includes a list of strings. These are urls to pictures and I'm using Picasso library to set in ImageView. I would like to set these images in an ImageSwitcher, and I dont know how to do it (I've done some researches before but no results). Thanks for helping guys !
