项目简介

  • 一款方便好用，让流式布局实现更简单的开源库，单选，多选，灵活配置，也可纯展示流式布局，流式布局item 也能随意自行配置。

项目引入

  • 将以下依赖项添加到build.gradle文件
dependencies {
    implementation 'com.mao:flexibleflowlayout:1.0.0'
}

Demo 展示

如何使用

  • xml 布局
<mao.com.flexibleflowlayout.TagFlowLayout
        android:id="@+id/tag_fl"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:maxLines = "1" // 显示的行数
        >
</mao.com.flexibleflowlayout.TagFlowLayout>
  • 简单指定数据适配器
TagFlowLayout tagFlowLayout;
//展示tag 数据 list
private List<String> dataList;
tagFlowLayout.setAdapter(new TagAdapter() {
            @Override
            public int getItemCount() {
                return dataList.size();
            }

            @Override
            public View createView(LayoutInflater inflater, ViewGroup parent, int position) {
               //每个 item 展示布局
                return inflater.inflate(R.layout.flow_text_sq_layout,parent,false);
            }

            @Override
            public void bindView(View view, int position) {
                TextView textView = view.findViewById(R.id.text_tag);
                textView.setText(dataList.get(position));
            }
        });
  • 也可以像recycleview 一样自己灵活设置adapter(具体可看demo)
public class MyTagAdapter extends TagAdapter{

        public void setDataList(List<String> dataList) {
            mDataList.clear();
            mDataList.addAll(dataList);
            notifyDataSetChanged();
        }

        private List<String> mDataList = new ArrayList<>();


        @Override
        public int getItemCount() {
            return mDataList.size();
        }

        @Override
        public View createView(LayoutInflater inflater, ViewGroup parent, int position) {
            return inflater.inflate(R.layout.flow_text_tag_layout,parent,false);
        }

        @Override
        public void bindView(View view, int position) {
            TextView textView = view.findViewById(R.id.flow_text_tag);
            textView.setText(mDataList.get(position));
        }
    }

属性设置

xml Attributes

name format description
android:maxLines int FlowLayout显示最大行数

方法

TagAdapter

method name return description
getItemCount() int 子元素的数量
createView() View 创建子View
bindView() void 绑定数据 根据外部数据确定子view 显示数据
onTagItemViewClick() void 每个 ItemView 的点击事件 （用户需要的时候自己实现）
tipForSelectMax() void 通知 到达了最大选择数（用户需要的时候自己实现）
onItemSelected() void item 被选中 可以根据自己的需求灵活设置 UI 样式
onItemUnSelected() void item 不被选中 可以根据自己的需求灵活设置 UI 样式
notifyDataSetChanged() void 数据刷新

TagFlowLayout

method name return description
setMaxSelectCount(int maxSelectCount) void 设置可以选择多少个tag 默认单选,设置为零 则没有单选和多选效果，纯展示tag
getSelectPositionItemList List 获取选中子View 的位置集合
