新版material-dialogs的java详细使用方法

新版的 material-dialogs已经改用Kotlin，而且sample也是使用Kotlin写的。想到介绍下如何使用java来调用，毕竟不能老是用老版本的吧。将原来Kotlin写的例子，用java完整改写了一遍。详细的所有用法，集成在文后的项目源码里。这里着重介绍几个代表的用法。

注意

因为使用了Lambda表达式，所以要在build.gradle中指定JDK版本

compileOptions {
	sourceCompatibility JavaVersion.VERSION_1_8
	targetCompatibility JavaVersion.VERSION_1_8
}

添加依赖

直接加最新的就行

implementation 'com.afollestad.material-dialogs:core:3.1.1'
implementation 'com.afollestad.material-dialogs:input:3.1.1'
implementation 'com.afollestad.material-dialogs:files:3.1.1'
implementation 'com.afollestad.material-dialogs:color:3.1.1'
implementation 'com.afollestad.material-dialogs:datetime:3.1.1'
implementation 'com.afollestad.material-dialogs:bottomsheets:3.1.1'
implementation 'com.afollestad.material-dialogs:lifecycle:3.1.1'
