AssembleEssay

自定义 LayoutManager 实现一个流动布局,可以用作文章展示,也可以用作标签展示,并且可以很方便地为其添加布局动画,示例代码里添加了拖拽插入的动画,如效果图。

对齐方式可选4中:

  1. 向左对齐
  2. 向右对齐
  3. 居中对齐
  4. 两边对齐

默认是两边对齐的布局方式

使用方式

  1. 先添加 jitpack
allprojects {
  repositories {
	 ...
	 maven { url 'https://jitpack.io' }
  }
}
  1. 在 module 对应得 build.gradle 文件中添加
implementation 'com.github.rantianhua:AssembleEssay:v1.0.0'
  1. 示例代码
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new FlowDragLayoutManager());

设置/更改对齐方式

//初始化是设置
//向左对齐
FlowDragLayoutManager layoutManager = new FlowDragLayoutManager(FlowDragLayoutConstant.LEFT);
//居中对齐
FlowDragLayoutManager layoutManager = new FlowDragLayoutManager(FlowDragLayoutConstant.CENTER);
//向右对齐
FlowDragLayoutManager layoutManager = new FlowDragLayoutManager(FlowDragLayoutConstant.RIGHT);
//居中对齐
FlowDragLayoutManager layoutManager = new FlowDragLayoutManager(FlowDragLayoutConstant.TWO_SIDE);

//动态更改
layoutManager.setAlignMode(FlowDragLayoutConstant.LEFT);
layoutManager.setAlignMode(FlowDragLayoutConstant.CENTER);
layoutManager.setAlignMode(FlowDragLayoutConstant.RIGHT);
layoutManager.setAlignMode(FlowDragLayoutConstant.TWO_SIDE);

优点

  1. 当标签很多的时候,可以重用视图,不会一次性产生过多对象
  2. 基于 RecyclerView 的 LayoutManager , 使用方便,而且添加动画效果也很容易
  3. 对齐方式灵活,目前四种应该n可以满足大部分的需求了
