android RecycleView实现多级树形列表

本文实例为大家分享了android RecycleView实现多级树形列表的具体代码，供大家参考，具体内容如下

实现多级树状列表：

1. Node.java

public class Node<T, B> implements Serializable { /** * 传入的实体对象 */ public B bean; /** * 设置开启的图片 */ public int iconExpand = -1; /** * 设置关闭的图片 */ public int iconNoExpand = -1; private T id; /** * 根节点pId为0 */ private T pId; private String name; /** * 当前的级别 */ private int level; /** * 是否展开 */ private boolean isExpand = false; private int icon = -1; /** * 下一级的子Node */ private List<Node> children = new ArrayList<>(); /** * 父Node */ private Node parent; /** * 是否被checked选中 */ private boolean isChecked; /** * 是否为新添加的 */ public boolean isNewAdd = true; /** * 单选标记 */ public boolean isSingle; /** * 支部code */ public String braCode; public Node(T id, T pId, String name) {super();this.id = id;this.pId = pId;this.name = name; } public Node(T id, T pId, String name, B bean) {super();this.id = id;this.pId = pId;this.name = name;this.bean = bean; } public String getBraCode() {return braCode; } public void setBraCode(String braCode) {this.braCode = braCode; } public boolean isSingle() {return isSingle; } public void setSingle(boolean single) {isSingle = single; } public boolean isChecked() {return isChecked; } public void setChecked(boolean isChecked) {this.isChecked = isChecked; } public Node() { } public int getIcon() {return icon; } public void setIcon(int icon) {this.icon = icon; } public T getId() {return id; } public void setId(T id) {this.id = id; } public T getpId() {return pId; } public void setpId(T pId) {this.pId = pId; } public String getName() {return name; } public void setName(String name) {this.name = name; } public void setLevel(int level) {this.level = level; } public boolean isExpand() {return isExpand; } public List<Node> getChildren() {return children; } public void setChildren(List<Node> children) {this.children = children; } public Node getParent() {return parent; } public void setParent(Node parent) {this.parent = parent; } /** * 是否为跟节点 * * @return */ public boolean isRoot() {return parent == null; } /** * 判断父节点是否展开 * * @return */ public boolean isParentExpand() {if (parent == null){ return false;}return parent.isExpand(); } /** * 是否是叶子界点 * * @return */ public boolean isLeaf() {return children.size() == 0; } /** * 获取level */ public int getLevel() {return parent == null ? 0 : parent.getLevel() + 1; } /** * 设置展开 * * @param isExpand */ public void setExpand(boolean isExpand) {this.isExpand = isExpand;if (!isExpand) { for (Node node : children) {node.setExpand(false); }} }}

2. OnTreeNodeClickListener.java

public interface OnTreeNodeClickListener { /** * 点击事件方法 * @param node 节点 * @param position 条目位置 */ void onClick(Node node, int position);}

3. TreeHelper.java

public class TreeHelper { /** * 传入node 返回排序后的Node * * @param datas 传入数据 * @param defaultExpandLevel 默认展开等级 * @return * @throws IllegalArgumentException * @throws IllegalAccessException */ public static List<Node> getSortedNodes(List<Node> datas, int defaultExpandLevel) {List<Node> result = new ArrayList<Node>();// 设置Node间父子关系List<Node> nodes = convetData2Node(datas);// 拿到根节点List<Node> rootNodes = getRootNodes(nodes);// 排序以及设置Node间关系for (Node node : rootNodes) { addNode(result, node, defaultExpandLevel, 1);}return result; } /** * 过滤出所有可见的Node * * @param nodes * @return */ public static List<Node> filterVisibleNode(List<Node> nodes) {List<Node> result = new ArrayList<Node>(); for (Node node : nodes) { // 如果为跟节点，或者上层目录为展开状态 if (node.isRoot() || node.isParentExpand()) {setNodeIcon(node);result.add(node); }}return result; } /** * 设置Node间，父子关系;让每两个节点都比较一次，即可设置其中的关系 */ private static List<Node> convetData2Node(List<Node> nodes) {for (int i = 0; i < nodes.size(); i++) { Node n = nodes.get(i); for (int j = i + 1; j < nodes.size(); j++) {Node m = nodes.get(j);//判断id是String，Integerif (m.getpId() instanceof String) { if (m.getpId().equals(n.getId())) {n.getChildren().add(m);m.setParent(n); } else if (m.getId().equals(n.getpId())) {m.getChildren().add(n);n.setParent(m); }} else if(m.getpId() instanceof Integer) { //这里就是修改的地方，因为这是Integer类，节点的地址是不一样的，所以不能直接使用==比较，要用equals()进行值的比较 if (m.getpId().equals(n.getId())) {n.getChildren().add(m);m.setParent(n); } else if (m.getId().equals(n.getpId())) {m.getChildren().add(n);n.setParent(m); }} }}return nodes; } /** * 获取所有根节点 * * @param nodes * @return */ private static List<Node> getRootNodes(List<Node> nodes) {List<Node> root = new ArrayList<Node>();for (Node node : nodes) { if (node.isRoot()) {root.add(node); }}return root; } /** * 把一个节点上的所有的内容都挂上去 */ private static <T, B> void addNode(List<Node> nodes, Node<T, B> node, int defaultExpandLeval, int currentLevel) {nodes.add(node);//判断添加新节点的时候，保持以前的状态不变if (node.isNewAdd && defaultExpandLeval >= currentLevel) { node.setExpand(true);} if (node.isLeaf()) { //判断是子节点 return;}for (int i = 0; i < node.getChildren().size(); i++) { addNode(nodes, node.getChildren().get(i), defaultExpandLeval, currentLevel + 1);} } /** * 设置节点的图标 * * @param node */ private static void setNodeIcon(Node node) {if (node.getChildren().size() > 0 && node.isExpand()) { node.setIcon(node.iconExpand);} else if (node.getChildren().size() > 0 && !node.isExpand()) { node.setIcon(node.iconNoExpand);} else { node.setIcon(-1);} }}

4. TreeRecyclerAdapter.java -----RecycleView形式的树形列表适配器

public abstract class TreeRecyclerAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { protected Context mContext; /** * 存储所有可见的Node */ protected List<Node> mNodes = new ArrayList<>(); protected LayoutInflater mInflater; /** * 存储所有的Node */ protected List<Node> mAllNodes = new ArrayList<>(); /** * 点击的回调接口 */ private OnTreeNodeClickListener onTreeNodeClickListener; /** * 默认不展开 */ private int defaultExpandLevel = 0; /** * 展开与关闭的图片 */ private int iconExpand = -1, iconNoExpand = -1;

for (Node node : datas) { node.getChildren().clear(); node.iconExpand = iconExpand; node.iconNoExpand = iconNoExpand;} this.defaultExpandLevel = defaultExpandLevel;mContext = context;/** * 对所有的Node进行排序 */mAllNodes = TreeHelper.getSortedNodes(datas, defaultExpandLevel);/** * 过滤出可见的Node */mNodes = TreeHelper.filterVisibleNode(mAllNodes);mInflater = LayoutInflater.from(context); } /** * @param mTree * @param context * @param datas * @param defaultExpandLevel 默认展开几级树 */ public TreeRecyclerAdapter(RecyclerView mTree, Context context, List<Node> datas, int defaultExpandLevel) {this(mTree, context, datas, defaultExpandLevel, -1, -1); } @Override public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {Node node = mNodes.get(position);//convertView = getConvertView(node, position, convertView, parent);// 设置内边距int padding = DisplayUtil.dp2px(mContext,5);holder.itemView.setPadding(DisplayUtil.dp2px(mContext,(node.getLevel()+1) * 15),padding,padding,padding); //然后设置单选，修改如下/** * 设置节点点击时，可以展开以及关闭,将事件继续往外公布 */holder.itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {//获取当前点击的位置layoutPosition = holder.getLayoutPosition();expandOrCollapse(position); if (onTreeNodeClickListener != null) { onTreeNodeClickListener.onClick(mNodes.get(position), position);} }}); if(position == layoutPosition){ node.setSingle(true);}else { node.setSingle(false);} onBindViewHolder(node, holder, position); } @Override public int getItemCount() {return mNodes.size(); } /** * 清除掉之前数据并刷新 重新添加 * * @param mlists * @param defaultExpandLevel 默认展开几级列表 */ public void addDataAll(List<Node> mlists, int defaultExpandLevel) {mAllNodes.clear();addData(-1, mlists, defaultExpandLevel);

} /** * 在指定位置添加数据并刷新 * * @param index * @param mlists */ public void addData(int index, List<Node> mlists) {notifyData(index, mlists); } /** * 添加数据并刷新 * * @param mlists */ public void addData(List<Node> mlists) {addData(mlists, defaultExpandLevel); } /** * 添加数据并刷新 可指定刷新后显示层级 * * @param mlists * @param defaultExpandLevel */ public void addData(List<Node> mlists, int defaultExpandLevel) {this.defaultExpandLevel = defaultExpandLevel;notifyData(-1, mlists); } /** * 添加数据并刷新 * * @param node */ public void addData(Node node) {addData(node, defaultExpandLevel); } /** * 添加数据并刷新 可指定刷新后显示层级 * * @param node * @param defaultExpandLevel */ public void addData(Node node, int defaultExpandLevel) {List<Node> nodes = new ArrayList<>();nodes.add(node);this.defaultExpandLevel = defaultExpandLevel;notifyData(-1, nodes);

node.iconExpand = iconExpand; node.iconNoExpand = iconNoExpand;}for (int i = 0; i < mAllNodes.size(); i++) { Node node = mAllNodes.get(i); node.getChildren().clear(); node.isNewAdd = false;}if (index != -1) { mAllNodes.addAll(index, mListNodes);} else { mAllNodes.addAll(mListNodes);}/** * 对所有的Node进行排序 */mAllNodes = TreeHelper.getSortedNodes(mAllNodes, defaultExpandLevel);/** * 过滤出可见的Node */mNodes = TreeHelper.filterVisibleNode(mAllNodes);//刷新数据notifyDataSetChanged(); } /** * 获取排序后所有节点 * * @return */ public List<Node> getAllNodes() {if (mAllNodes == null){ mAllNodes = new ArrayList<Node>();}return mAllNodes; } /** * 相应ListView的点击事件 展开或关闭某节点 * * @param position */ public void expandOrCollapse(int position) {Node n = mNodes.get(position); if (n != null) { // 排除传入参数错误异常 if (!n.isLeaf()) {n.setExpand(!n.isExpand());mNodes = TreeHelper.filterVisibleNode(mAllNodes);notifyDataSetChanged();// 刷新视图 }} } /** * 设置多选 * * @param node * @param checked */ protected void setChecked(final Node node, boolean checked) {node.setChecked(checked);setChildChecked(node, checked);if (node.getParent() != null){ setNodeParentChecked(node.getParent(), checked);}notifyDataSetChanged(); } /** * 设置是否选中 * * @param node * @param checked */ public <T, B> void setChildChecked(Node<T, B> node, boolean checked) {if (!node.isLeaf()) { node.setChecked(checked); for (Node childrenNode : node.getChildren()) {setChildChecked(childrenNode, checked); }} else { node.setChecked(checked);} } private void setNodeParentChecked(Node node, boolean checked) {if (checked) { node.setChecked(checked); if (node.getParent() != null){setNodeParentChecked(node.getParent(), checked); }} else { List<Node> childrens = node.getChildren(); boolean isChecked = false; for (Node children : childrens) {if (children.isChecked()) { isChecked = true;} } //如果所有自节点都没有被选中 父节点也不选中 if (!isChecked) {node.setChecked(checked); } if (node.getParent() != null){setNodeParentChecked(node.getParent(), checked); }} } public abstract void onBindViewHolder(Node node, RecyclerView.ViewHolder holder, final int position); //===================在这里添加修改选中位置的方法===================== /** * 设置选中位置 * @param selectedPosition */ public void setSelectedPosition(int selectedPosition) {this.layoutPosition = selectedPosition; }}

5. 自定义样式：

TypeTreeRecyclerAdapter.java

public class TypeTreeRecyclerAdapter extends TreeRecyclerAdapter { private static final String TAG = 'TypeTreeRecyclerAdapter'; private boolean isSingle; public TypeTreeRecyclerAdapter(RecyclerView mTree, Context context, List<Node> datas, int defaultExpandLevel, int iconExpand, int iconNoExpand,boolean isSingle) {super(mTree, context, datas, defaultExpandLevel, iconExpand, iconNoExpand);this.isSingle = isSingle; } public TypeTreeRecyclerAdapter(RecyclerView mTree, Context context, List<Node> datas, int defaultExpandLevel) {super(mTree, context, datas, defaultExpandLevel); } @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {return new MyHoder(View.inflate(mContext, R.layout.tree_list_item,null)); } @Override public void onBindViewHolder(final Node node, RecyclerView.ViewHolder holder, int position) {final MyHoder viewHolder = (MyHoder) holder;//todo do somethingviewHolder.cb.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {//setChecked(node,viewHolder.cb.isChecked());setChildChecked(node,viewHolder.cb.isChecked());listener.onItemClick(position); }});viewHolder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton compoundButton, boolean b) {if (isSingle) { if (b) { //如果checkbox的状态是选中的，那么除了被选中的那条数据，其他Node节点的checkbox状态都为falsefor (int i = 0; i < mAllNodes.size(); i++) { if (((Node) mAllNodes.get(i)).getId().equals(node.getId())) { Log.e(TAG,'note='+mAllNodes.get(i).getName());((Node) mAllNodes.get(i)).setChecked(b); } else {//Log.e(TAG,'1111 note='+mAllNodes.get(i).getName());((Node) mAllNodes.get(i)).setChecked(false); }} } else {//如果checkbox的状态是选中的，所有Node节点checkbox状态都为falsefor (int i = 0; i < mAllNodes.size(); i++) { if (((Node) mAllNodes.get(i)).getId().equals(node.getId())) {((Node) mAllNodes.get(i)).setChecked(b); }} }} else { 如果checkbox是多选的，对应node节点的checkbox状态视用户的操作而定 for (int i = 0; i < mAllNodes.size(); i++) {if (((Node) mAllNodes.get(i)).getId().equals(node.getId())) ((Node) mAllNodes.get(i)).setChecked(b); }} }}); if (node.isChecked()){ viewHolder.cb.setChecked(true);}else { viewHolder.cb.setChecked(false);} if (node.getIcon() == -1) { viewHolder.icon.setVisibility(View.INVISIBLE);} else { viewHolder.icon.setVisibility(View.VISIBLE); viewHolder.icon.setImageResource(node.getIcon());} viewHolder.label.setText(node.getName()); } public interface onAItemClickListener{void onItemClick(int position); } private onAItemClickListener listener; public void setOnItemClickListener (onAItemClickListener onItemClickListener) {listener = onItemClickListener; } class MyHoder extends RecyclerView.ViewHolder{public CheckBox cb;public TextView label;public ImageView icon;public MyHoder(View itemView) { super(itemView); cb = (CheckBox) itemView.findViewById(R.id.cb_select_tree); label = (TextView) itemView.findViewById(R.id.id_treenode_label); icon = (ImageView) itemView.findViewById(R.id.icon);} }}

case R.id.btn_cancel:if ( onClickBottomListener!= null) { onClickBottomListener.onNegtiveClick();}break;} }}

8. 调用dialog

OfficeTypeDialog typeDialog = new OfficeTypeDialog(mContext,R.style.Dialog,'officeType'); typeDialog.setOnClickBottomListener(new OfficeTypeDialog.OnClickBottomListener() { @Override public void onPositiveClick(TypeTreeBean typeBean) {tv_officeType.setText(typeBean.getName());officeType = typeBean;typeDialog.dismiss(); } @Override public void onNegtiveClick() {typeDialog.dismiss(); }});typeDialog.show();
