RecyclerView是否必须属于ImageView

Answer 1

这样的东西？

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

    <ImageView
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_below="@+id/recycler"/>

</RelativeLayout>

关键是向ImageView添加ndroid:layout_below="@+id/recycler"。

修改

您也可以尝试这样的事情。首先创建从CoordinatorLayout.Behavior扩展的类，然后将新行为附加到ImageView。请记住，RecyclerView和Image View必须是CoordinatorLayout的子项。

public class FixedBottomViewBehavior extends CoordinatorLayout.Behavior<View> { public FixedBottomViewBehavior() { } public FixedBottomViewBehavior(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) { return dependency instanceof RecyclerView; } @Override public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) { if (ViewCompat.isLaidOut(parent)) { //attach our bottom view to the bottom of CoordinatorLayout child.setY(parent.getBottom() - child.getHeight()); //set bottom padding to the dependency view to prevent bottom view from covering it dependency.setPadding(dependency.getPaddingLeft(), dependency.getPaddingTop(), dependency.getPaddingRight(), child.getHeight()); } return false; } }

然后在xml：

<android.support.design.widget.CoordinatorLayout 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.support.v7.widget.RecyclerView android:id="@+id/recycler" android:layout_width="match_parent" android:layout_height="wrap_content" /> <ImageView android:layout_width="200dp" android:layout_height="200dp" app:layout_behavior="your.package.address.FixedBottomViewBehavior"/> </android.support.design.widget.CoordinatorLayout>

1）为页脚创建一个视图

    if (viewType == MY_FOOTER_VIEW) {
        v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_list_item_footer, parent, false);

        FooterViewHolder footerViewHolder= new FooterViewHolder(v);

        return vh;
    }

 //your regular viewholder inflation

2）现在onCreateViewHolder（）检查正确的viewholder 根据需要给页脚或常规查看者充气：

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

    try {
        if (holder instanceof NormalViewHolder) {
            NormalViewHolder vh = (NormalViewHolder) holder;

            vh.bindView(position);
        } else if (holder instanceof FooterViewHolder) {
            FooterViewHolder vh = (FooterViewHolder) holder;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

3）执行正确的绑定：

 return data.size() + 1;

4）on getItemCount（）返回+1元素

@Override
public int getItemViewType(int position) {
    if (position == data.size()) {
        // This is where we'll add footer.
        return FOOTER_VIEW;
    }

    return super.getItemViewType(position);
}

5）覆盖getItemViewType（）以标识您的新类型页脚。
