问题 After reading the new design guidelines of Google's material design, I didn't found any clear solution for designing/displaying a spinner (http://developer.android.com/design/building-blocks/spinners.html) in material design. The nearest would be something like this: http://material-design.storage.googleapis.com/publish/v_1/quantumexternal/0Bx4BSt6jniD7anplVHR3QkdNUHc/components_menus_behavior2.png - but I'm quite sure, there will be some better solution.

问题 Spinner with checkbox items, is it possible? 回答1: That depends on what you mean. If you want a true multi-select Spinner , then there's nothing built into Android for that.
