首先来个效果图

布局文件代码

在布局文件中，CoordinatorLayout作为布局文件根节点，AppBarLayout包含在CoordinatorLayout中，toolbar在AppBarLayout节点下include进来。

<?xml version="1.0" encoding="utf-8"?><android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="cn.manchester.androidsupportlibrary.CoordinatorLayoutActivity"> <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:fitsSystemWindows="true"> <include layout="@layout/toolbar" /> </android.support.design.widget.AppBarLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:scrollbars="none" app:layout_behavior="@string/appbar_scrolling_view_behavior"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout></android.support.design.widget.CoordinatorLayout>

toolbar.xml

toolbar是需要响应view的滚动事件的，所以需要为toolbar指定layout_scrollFlags属性，scroll表示toobar会随着view的向下滚动而隐藏，enterAlways表示toolbar会随着view的向上滚动而恢复到原来的位置。

<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#304696" android:popupTheme="@style/ThemeOverlay.AppCompat.Light" app:layout_scrollFlags="scroll|enterAlways" app:theme="@style/ThemeOverlay.AppCompat.ActionBar"></android.support.v7.widget.Toolbar>

Java代码

public class CoordinatorLayoutActivity extends AppCompatActivity { Toolbar mToolbar; RecyclerView mRecyclerView; String[] mArrays = new String[]{"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_coordinator_layout); mToolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(mToolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView); mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); mRecyclerView.setAdapter(new MyAdapter()); } class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> { @Override public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { MyViewHolder holder = new MyViewHolder(LayoutInflater.from(CoordinatorLayoutActivity.this) .inflate(android.R.layout.simple_list_item_1, parent, false)); return holder; } @Override public void onBindViewHolder(MyAdapter.MyViewHolder holder, int position) { holder.tv.setText(mArrays[position]); } @Override public int getItemCount() { return mArrays.length; } class MyViewHolder extends RecyclerView.ViewHolder { TextView tv; public MyViewHolder(View itemView) { super(itemView); tv = (TextView) itemView.findViewById(android.R.id.text1); } } }}
