不能使用在ImageView的setForeground方法可以 [英] Can't use setForeground method on ImageView
问题描述
我想使用setForeground方法可以展现在我的ImageView市中心的播放图标指示用户,如果他们preSS视频将发挥它。
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.
目前,我有这个错误,我解决不了:
Currently I'm having this error which I cannot solve:
虽然文件说的方法应该是可用,因为API 1:
Although the documentation says the method should be available since API 1:
我定位和对编译与构建工具版本23.0.1 API 23。我针对分16 API
I'm targeting and compiling against API 23 with build tools version 23.0.1. I'm targeting min API 16.
推荐答案
这是的文档错误。 setForeground()
在的FrameLayout
从API等级1存在;看来,只有在查看
的API级别的23。
That is a documentation bug. setForeground()
existed on FrameLayout
from API Level 1; it is only on View
as of API Level 23.
