RecyclerView 實現橫向滾動與瀑布流佈局

Recyclerview的使用方式方式與ListView大致相似，關鍵代碼如下：
橫向滾動代碼段：
Recyclerview recyclerview = (Recyclerview)findViewById(R.id.recyclerview);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
recyclerview.setLayoutManager(layoutManager);
MyAdapter adapter = new Myadater();
recyclerview.setAdaper(adapter);

瀑布流佈局代碼段：
Recyclerview mRecyclerView = (Recyclerview)findViewById(R.id.recyclerview);
StaggeredGridLayoutManager mLayoutManager = new StaggeredGridLayoutManager(columnNum, StaggeredGridLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(mLayoutManager);
MyAdapter adapter = new Myadater();
mRecyclerView.setAdaper(adapter);
