不能在 ImageView 上使用 setForeground 方法

Can#39;t use setForeground method on ImageView(不能在 ImageView 上使用 setForeground 方法)

问题描述

I want to use the setForeground method to show a "play" icon in the center of my ImageView to indicate the user that a video will play if they press it.

Currently I'm having this error which I cannot solve:

Although the documentation says the method should be available since API 1:

I'm targeting and compiling against API 23 with build tools version 23.0.1. I'm targeting min API 16.

That is a documentation bug. setForeground() existed on FrameLayout from API Level 1; it is only on View as of API Level 23.
