如何在android中使用recyclerview添加多个视图？

Question

我在屏幕上有多个视图。

如何包括在我的屏幕底部的屏幕和recyclerview的顶部我的版面内容？

在此先感谢..

Answer 1

这取决于你想添加什么样的顶面布置的。

如果你想添加图片或查看传呼机与滑动图像，那么它最好使用CollapsingToolbarLayout与AppBarLayout里面CoordinatorLayout，然后添加您的RecyclerView。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@color/white">

        <ImageView

       </LinearLayout> 
       <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"

        app:layout_collapseMode="pin"/> 

      </android.support.design.widget.CollapsingToolbarLayout> 

     </android.support.design.widget.AppBarLayout>

       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       /> 
</android.support.v4.widget.SwipeRefreshLayout> 


    </android.support.design.widget.CoordinatorLayout> 
    <ProgressBar 
     android:id="@+id/progress" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" 
     /> 

</RelativeLayout>

你可以做到这一点的方式，包括多个视图：

@Override 
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     switch (viewType) { 
      case 0: return new ViewHolder0(...); 
      case 2: return new ViewHolder2(...); 

     } 
    } 

参考RecyclerView with multiple view type。

Answer 3

它可以通过重写该方法中，getItemViewType（INT位置）来完成这指定膨胀为回收站视图

@Override 
    public int getItemViewType(int position) { 
     if (position == 0) 
      return LAYOUT_TYPE_0; 
     else if (position == 1) 
      return LAYOUT_TYPE_1; 
     else 
      return LAYOUT_TYPE_ITEM; 
    } 

这里的perticular位置，其布局是完整适配器代码

public class RecyclerViewAdapter extends RecyclerView.Adapter { 

     public static final int LAYOUT_TYPE_0 = 0; 
     public static final int LAYOUT_TYPE_1 = 1; 
     public static final int LAYOUT_TYPE_ITEM = 2; 


     @Override 
     public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
      if (viewType == LAYOUT_TYPE_0) { 
       View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_0, parent, false); 
       return new LayoutPos0(view); 
      } else if (viewType == LAYOUT_TYPE_1) { 
       View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_1, parent, false); 
       return new LayoutPos1(view); 
      } else { 
       View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_common, parent, false); 
       return new LayoutCommon(view); 
      } 

     } 

     @Override 
     public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {    
     } 

     @Override 
     public int getItemViewType(int position) { 
      if (position == 0) 
       return LAYOUT_TYPE_0; 
      else if (position == 1) 
       return LAYOUT_TYPE_1; 
      else 
       return LAYOUT_TYPE_ITEM; 
     } 



     public class LayoutPos0 extends RecyclerView.ViewHolder { 
       //your code goes here 
     } 

     private class LayoutPos1 extends RecyclerView.ViewHolder { 
     } 

     private class LayoutCommon extends RecyclerView.ViewHolder{   
    } 

@Override 
     public int getItemCount() { 
      return 100; 
     } 

}
