Android多级选择控件，单级单选，单级多选，多级单选，多级多选

1.导入依赖

implementation 'com.github.Tomzem:MultiLevelSelect:1.0.1'

2.在Project的build.gradle中添加:

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

3.xml布局

4.和平常用的适配器一样

       mLvMultiSelect = findViewById(R.id.lv_select);
        mItems = new ArrayList<>();
        initData();
				
        mAdapter = new ListViewAdapter(mLvMultiSelect, this, mItems, 0);
        mLvMultiSelect.setAdapter(mAdapter);
	//点击选中监听
        mAdapter.setCheckedChangeListener(new OnTreeNodeCheckedChangeListener() {
            @Override
            public void onCheckChange(String id, String name, int position, boolean isChecked) {
                List selectedNode = mAdapter.getSelectedNode();
                for (Node node : selectedNode){
                    Log.d(TAG, "selectedNode: " + node.getId());
                }
            }
        });

    private void initData() {
        List items = new ArrayList<>();
        items.add(new Item(0, -1, "菜单1"));
        items.add(new Item(1, -1, "菜单2"));
        items.add(new Item(2, -1, "菜单3"));
        items.add(new Item(3, -1, "菜单4"));

        items.add(new Item(4, 0, "菜单1-1"));
        items.add(new Item(5, 0, "菜单1-2"));
        items.add(new Item(6, 0, "菜单1-3"));

        items.add(new Item(7, 1, "菜单2-1"));
        items.add(new Item(8, 1, "菜单2-2"));
        items.add(new Item(9, 1, "菜单2-3"));

        items.add(new Item(10, 2, "菜单3-1"));
        items.add(new Item(11, 2, "菜单3-2"));
        items.add(new Item(12, 2, "菜单3-3"));

        items.add(new Item(14, 3, "菜单4-1"));
        items.add(new Item(15, 3, "菜单4-2"));
        items.add(new Item(16, 3, "菜单4-3"));

        mItems.addAll(items);
    }
}
