2.修改布局管理器从大到ListView,GridView,瀑布流的效果
private void initList()
{
//实现listView的效果
// 可以垂直滑动，也可以水平滑动，数据反向加载
//设置布局管理器
LinearLayoutManager layoutManager = new LinearLayoutManager(this,
LinearLayoutManager.VERTICAL,
false);
mRecyclerView.setLayoutManager(layoutManager);
//设置adapter
mRecyclerView.setAdapter(new ListAdapter(this,
mListDatas));//adapter ---> list数据
}
private void initGrid()
{
//实现listView的效果
// 可以垂直滑动，也可以水平滑动，数据反向加载
//设置布局管理器
GridLayoutManager layoutManager = new GridLayoutManager(this,
2,
GridLayoutManager.VERTICAL,
false);
mRecyclerView.setLayoutManager(layoutManager);
//设置adapter
mRecyclerView.setAdapter(new ListAdapter(this,
mListDatas));//adapter ---> list数据
}
private void initStragger()
{
//实现listView的效果

//设置布局管理器
StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(layoutManager);
//设置adapter
mRecyclerView.setAdapter(new StraggerdAdpater(this,

3.瀑布了需要改item的样式Card
