AndroidWidget

Useful Android Widget Library

SwipeLayout 用于实现RecyclerView实现Item侧滑效果
FacePreview 用于摄像头扫描（2018年3月19日新增）

效果图

使用步骤

1. 在Module(app模块)的build.gradle添加依赖

dependencies {
  compile 'cn.ltaoj.widget:widget:0.9.8'
}

2. 新建activity_test布局文件

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:scrollbars="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </android.support.v7.widget.RecyclerView>

</android.support.constraint.ConstraintLayout>

3. 新建item_member_list.xml布局文件，用于显示RecycleView显示每个条目

可以看到这个布局文件根布局为SwipeLayout控件，使用这个控件需要注意以下点：

SwipeLayout下需要有两个ViewGroup子视图
第一个子视图为backLayout
第二个子视图为frontLayout
子视图顺序不能相反，否则估计你将会看到相反的结果

<?xml version="1.0" encoding="utf-8"?>
<cn.ltaoj.widget.SwipeLayout
