AndroidPicker的使用

参考：

https://github.com/gzu-liyujiang/AndroidPicker

效果图：

一、添加依赖：

project：build.gradle

allprojects {
    repositories {
        jcenter()

        maven { url "https://jitpack.io"}
    }
}

app：build.gradle

    compile 'com.alibaba:fastjson:1.1.55.android'

    compile('com.github.gzu-liyujiang.AndroidPicker:WheelPicker:1.5.4') {
        exclude group: 'com.android.support'
    }
//    compile('com.github.gzu-liyujiang.AndroidPicker:FilePicker:1.5.4') {
//        exclude group: 'com.android.support'
//    }
//    compile('com.github.gzu-liyujiang.AndroidPicker:ColorPicker:1.5.4') {
//        exclude group: 'com.android.support'
//    }

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
