Android : Floating Clickable Icon over Screen?
提问by st0le
There's an Android Application called Smart Taskbarthat manages to Pin a small SemiTransparent Icon over the screen...The icon remains visible over ALLthe activites (including the home screen). The Icon is Clickable (/Touchable), and it does popopen a Small Popup window which the user can interact with.
有一个名为的 Android 应用程序Smart Taskbar可以在屏幕上固定一个小的半透明图标......该图标在所有活动（包括主屏幕）上保持可见。图标是可点击的（/可触摸），它确实弹出一个用户可以与之交互的小弹出窗口。
I'm very interested in how this is done? I think it's something to with PopupWindow.
