Implementation steps

First, in the XML layout

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <! -- some layout here --> <ch.ielse.demo.p02.ImageWatcher android:id="@+id/v_image_watcher" android:layout_width="match_parent" android:layout_height="match_parent"/> <! - in the cover to the bottom of the layout of a ImageWatcher ImageWatcher initialization is INVISIABLE by default -- > < / FrameLayout >Copy the code

After that, the Activity onCreate usually needs to call these three apis for simple initialization

ImageWatcher vImageWatcher = (ImageWatcher) findViewById(R.id.v_image_watcher); / / if the status bar is transparent, you need to give ImageWatcher marked an offset value, to correct click ImageView start animation Y starting point of view of incorrect vImageWatcher. SetTranslucentStatus (! isTranslucentStatus ? Utils.calcStatusBarHeight(this) : 0); / / configuration error icon vImageWatcher. SetErrorImageRes (R.m ipmap. Error_picture); / / long according to the pictures of the callback, you can display a box to provide some copy, send the function such as vImageWatcher. SetOnPictureLongPressListener (this);Copy the code

By this time all your preparations will have been completed

/** * @param ImageView * @param ImageView * @param ImageView * @param ImageView * @param urlList List of loaded image urls. The number must be greater than or equal to imageGrouplist.size. Public void show(ImageView I, List<ImageView> imageGroupList, final List<String> urlList) { ... }Copy the code

And the last thing you need to do is call vimageWatcher.show () and you can look at the source code demo, and this project will work, this project will work, this project will work
