Android编程入门--RecyclerView使用 _android编程

博观而约取，厚积而薄发。这篇文章主要讲述Android编程入门--RecyclerView使用相关的知识，希望能为你提供帮助。
布局

< android.support.v7.widget.RecyclerView android:id="@+id/rv_department" android:layout_width="match_parent" android:layout_height="match_parent" android:clipChildren="false" android:clipToPadding="false" android:padding="8dp" />

item 布局

< ?xml version="1.0" encoding="utf-8"?> < RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> < android.support.v7.widget.CardView android:layout_width="match_parent" android:layout_height="match_parent" android:layout_centerInParent="true" android:layout_margin="8dp"> < TextView android:id="@+id/tv" android:layout_width="match_parent" android:layout_height="36dp" android:background="@drawable/bg_white_to_gray" android:foreground="?attr/selectableItemBackground" android:gravity="center"/> < /android.support.v7.widget.CardView> < /RelativeLayout>

Adapter

public class DeptAdapter extends RecyclerView.Adapter< DeptAdapter.ViewHolder> {public String[] datas = null; public DeptAdapter(String[] datas) { this.datas = datas; }@Override public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) { View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_dept,viewGroup,false); ViewHolder vh = new ViewHolder(view); return vh; }@Override public void onBindViewHolder(ViewHolder viewHolder, int position) { viewHolder.mTextView.setText(datas[position]); }@Override public int getItemCount() { return datas.length; }class ViewHolder extends RecyclerView.ViewHolder { private TextView mTextView; public ViewHolder(View view){ super(view); mTextView = (TextView) view.findViewById(R.id.tv); } } }

GridLayoutManager方式

GridLayoutManager manager = new GridLayoutManager(this, 4); rv_department.setLayoutManager(manager); rv_department.setItemAnimator(new DefaultItemAnimator()); //设置动画 DeptAdapter mAdapter = new DeptAdapter(new String[]{"东润","研发部","科技"}); rv_department.setAdapter(mAdapter);
