Install / Use
/learn @AnJiaoDe/SlidingMenuVerticalREADME
使用方法
将libray模块复制到项目中,或者直接在build.gradle中依赖:
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
dependencies {
api 'com.github.AnJiaoDe:SlidingMenuVertical:V1.1.5'
}
注意：如果sync报错，是因为和com.android.tools.build:gradle 3.0有关， 可以改将compile改为implementation 或者api
注意：布局一定是SlidingMenuVertical包含2个直接子View
