SwipeDragTreeRecyclerView-可滑动和拖拽的树形结构RecyclerView.zip

功能树形结构 RecyclerView支持滑动删除支持长按拖拽支持单个 view 点击或长按时拖拽可开启并更改滑动删除背景色可自由指定滑动删除和拖拽操作的方向展开关闭全部分组下载Demo：下载截图使用方法添加jitpack库//build.gradle(Project:)  allprojects {       repositories {     ...      maven { url 'https://www.jitpack.io' }      }     }添加依赖 //build.gradle(Module:)dependencies {    compile 'com.github.goweii:SwipeDragTreeRecyclerView:v1.2.0'  }在xml布局文件中使用官方RecyclerView<android.support.v7.widget.RecyclerView android:id="@ id/swipe_drag_tree_recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" > </android.support.v7.widget.RecyclerView>继承 TreeState 增加几个静态变量，用于标识 item 的类别当然，你的数据应该存放在 TreeState 中public class TestTreeState extends TreeState {     public static final int TYPE_ONE = 1;     public static final int TYPE_TEO = 2;     public static final int TYPE_THREE = 3;     public static final int TYPE_FOUR = 4; }用你的 adapter 继承 BaseSwipeDragTreeAdapter 实现几个方法putTypeLayoutViewIds(int viewType, int layoutId, int[] viewIds, int[] clickFlags) 这4个参数的含义为：putTypeStartDragViewIds(int viewType, @IdRes int[] viewIds, int[] startDragFlags) 如果你想让某一个 view 在点击或者长按时实现拖拽，而不是在长按整个 item 时，应该调用这个方法完成配置viewType 类别 继承 TreeState 增加的静态变量layoutId 布局idviewIds 布局中需要用到的 view 的 idclickFlags 设置 view 是否需要点击事件，设置为 null 时默认不开启长按和单击， ClickFlag 为 adapter 的静态内部类，你直接使用即可viewType 布局类型viewIds 拖拽操作的 view 的 idstartDragFlags 拖拽标志，StartDragFlag 为 adapter 的静态内部类，你直接使用即可initIds() 在这个方法中你应该调用下面2个方法完成相关初始化bindData(BaseViewHolder holder, TypeData data) 你应该调用 holder.getItemViewType() 方法得到自定义的 item 的类别，依据类别判断 holder 绑定的数据类型，然后调用 holder 的 getView 方法获取 view 实例进行数据绑定public class TestBaseSwipeDragTreeAdapter extends BaseSwipeDragTreeAdapter {     private final int mOrientationType;     public TestBaseSwipeDragTreeAdapter(int orientationType) {         super();         mOrientationType = orientationType;     }     @Override     public void initIds() {         putTypeLayoutViewIds(TestTreeState.TYPE_ONE, R.layout.item1_swipe_drag_tree_recycler_view,                 new int[]{R.id.item1_sdtrv_tv}, null);
