CollapsingToolbarLayout與RecyclerView

Question

我一直在試圖實現CollapsingToolbar與使用RecyclerView

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/main_content" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true"> 

<android.support.design.widget.AppBarLayout 
    android:id="@+id/appbar" 
    android:layout_width="match_parent" 
    android:layout_height="300dp" 
    android:fitsSystemWindows="true" 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/collapsing_toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fitsSystemWindows="true" 
     app:contentScrim="?attr/colorPrimary" 
     app:expandedTitleMarginEnd="64dp" 
     app:expandedTitleMarginStart="48dp" 
     app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

     <ImageView 
      android:id="@+id/imageView_list" 
      android:layout_width="match_parent" 
      android:layout_height="275dp" 
      app:layout_collapseMode="parallax" 
      android:fitsSystemWindows="true" 
      android:scaleType="fitXY" 
      android:src="@mipmap/bg_profile_01" /> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      app:layout_collapseMode="pin" 
      app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /> 
    </android.support.design.widget.CollapsingToolbarLayout> 
</android.support.design.widget.AppBarLayout> 

     <android.support.v7.widget.RecyclerView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/list"/> 
</android.support.design.widget.CoordinatorLayout> 

list.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="50dp" 
android:orientation="vertical"> 
<ImageView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/item_img" 
    android:adjustViewBounds="true" 
    /> 
<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/item_txt" 
    android:gravity="center" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:paddingTop="5dp" 
    android:paddingBottom="5dp" 
    android:layout_centerInParent="true" 
    /> 

適配器

public class ViewAdapter extends RecyclerView.Adapter<ViewAdapter.ViewHolder> { 

Context context; 
private List<ViewModel> items; 
private int itemLayout; 

public ViewAdapter(Context context,List<ViewModel> items,int itemLayout) { 
    this.context = context; 
    this.items = items; 
    this.itemLayout = itemLayout; 
} 

@Override 
public int getItemCount() { 
    return items.size(); 
} 

@Override 
public void onBindViewHolder(ViewHolder holder, int position) { 
    ViewModel item = items.get(position); 
    holder.itemView.setTag(item); 
    holder.text.setText(item.getTitle()); 

} 

@Override 
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(itemLayout, parent, false); 
    /*if(parent.getHeight() > 0){ 
     view.getLayoutParams().height = parent.getHeight()/6; 
    }*/ 
    ViewHolder vh = new ViewHolder(view, new ViewHolder.AdapterClickListener() { 
     @Override 
     public void onAadapterItemClick(View view, int position) { 
      items.remove(position); 
      notifyItemRemoved(position); 
     } 
    }); 
    return vh; 
} 


public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 
    public ImageView image; 
    public TextView text; 
    public AdapterClickListener adapterClickListener; 

    public ViewHolder(View itemView, AdapterClickListener adapterClickListener) { 
     super(itemView); 
     this.adapterClickListener = adapterClickListener; 
     image = (ImageView)itemView.findViewById(R.id.item_img); 
     text=(TextView)itemView.findViewById(R.id.item_txt); 
     itemView.setOnClickListener(this); 
    } 
    @Override 
    public void onClick(View v) { 
     adapterClickListener.onAadapterItemClick(v, getAdapterPosition()); 
    } 

    public static interface AdapterClickListener { 
     public void onAadapterItemClick(View view, int position); 
    } 
} 

主要

private void init(){ 
    recyclerView = (RecyclerView)findViewById(R.id.list); 
    recyclerView.setHasFixedSize(true); 
    recyclerView.setAdapter(new ViewAdapter(getApplicationContext(), CreateItemList(), R.layout.item_list)); 
    recyclerView.setItemAnimator(new DefaultItemAnimator()); 
    recyclerView.setLayoutManager(new LinearLayoutManager(this)); 

} 

private List<ViewModel> CreateItemList(){ 
    List<ViewModel> items = new ArrayList<ViewModel>(); 
    for(int i=0;i<20;i++){ 
     ViewModel model = new ViewModel(); 
     model.setTitle("title_" + i); 

     items.add(model); 
    } 
    return items; 
} 

但RecyclerView佔據了整個屏幕

我不知道什麼時候開始出問題。

對不起，我真的在英語不好ㅠ_ㅠ

只需添加：app:layout_behavior="@string/appbar_scrolling_view_behavior"您回收站查看。

它看起來是這樣的：

<android.support.v7.widget.RecyclerView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/list" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
