最好的解决方案是在一个视图/视图组中保持多个视图，然后在SrcollView中保持一个视图。ie。

格式- - -

<ScrollView> 
  <Another View>
       <RecyclerView>
       <TextView>
       <And Other Views>
  </Another View>
</ScrollView>

Eg.

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>


        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>
 </ScrollView>

另一个。ScrollView的多个视图

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:orientation="vertical"
            android:layout_weight="1">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/imageView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#FFFFFF"
                />

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingHorizontal="10dp"
                android:orientation="vertical">

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/CategoryItem"
                    android:textSize="20sp"
                    android:textColor="#000000"
                    />

                <TextView
                    android:textColor="#000000"
                    android:text="₹1000"
                    android:textSize="18sp"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>
                <TextView
                    android:textColor="#000000"
                    android:text="so\nugh\nos\nghs\nrgh\n
                    sghs\noug\nhro\nghreo\nhgor\ngheroh\ngr\neoh\n
                    og\nhrf\ndhog\n
                    so\nugh\nos\nghs\nrgh\nsghs\noug\nhro\n
                    ghreo\nhgor\ngheroh\ngr\neoh\nog\nhrf\ndhog"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

             </LinearLayout>

        </LinearLayout>

</ScrollView>

看起来NestedScrollView确实解决了这个问题。

我使用这个布局进行了测试:

<android.support.v4.widget.NestedScrollView
    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:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/dummy_text" />

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="16dp"
            android:layout_marginRight="16dp">

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

        </android.support.v7.widget.CardView>

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

而且它没有任何问题。

首先，你应该使用NestedScrollView而不是ScrollView，并把RecyclerView放在NestedScrollView里面。

使用自定义布局类测量屏幕的高度和宽度:

public class CustomLinearLayoutManager extends LinearLayoutManager {

public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
    super(context, orientation, reverseLayout);
}

private int[] mMeasuredDimension = new int[2];

@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    final int widthMode = View.MeasureSpec.getMode(widthSpec);
    final int heightMode = View.MeasureSpec.getMode(heightSpec);
    final int widthSize = View.MeasureSpec.getSize(widthSpec);
    final int heightSize = View.MeasureSpec.getSize(heightSpec);
    int width = 0;
    int height = 0;
    for (int i = 0; i < getItemCount(); i++) {
        if (getOrientation() == HORIZONTAL) {
            measureScrapChild(recycler, i,
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    heightSpec,
                    mMeasuredDimension);

            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            measureScrapChild(recycler, i,
                    widthSpec,
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }
    switch (widthMode) {
        case View.MeasureSpec.EXACTLY:
            width = widthSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    switch (heightMode) {
        case View.MeasureSpec.EXACTLY:
            height = heightSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    setMeasuredDimension(width, height);
}

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {
    View view = recycler.getViewForPosition(position);
    recycler.bindViewToPosition(view, position);
    if (view != null) {
        RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
        int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                getPaddingLeft() + getPaddingRight(), p.width);
        int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                getPaddingTop() + getPaddingBottom(), p.height);
        view.measure(childWidthSpec, childHeightSpec);
        measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
        measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
        recycler.recycleView(view);
    }
}
}

并在RecyclerView的活动/片段中实现以下代码:

 final CustomLinearLayoutManager layoutManager = new CustomLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);

    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(mAdapter);

    recyclerView.setNestedScrollingEnabled(false); // Disables scrolling for RecyclerView, CustomLinearLayoutManager used instead of MyLinearLayoutManager
    recyclerView.setHasFixedSize(false);

    recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);

            int visibleItemCount = layoutManager.getChildCount();
            int totalItemCount = layoutManager.getItemCount();
            int lastVisibleItemPos = layoutManager.findLastVisibleItemPosition();
            Log.i("getChildCount", String.valueOf(visibleItemCount));
            Log.i("getItemCount", String.valueOf(totalItemCount));
            Log.i("lastVisibleItemPos", String.valueOf(lastVisibleItemPos));
            if ((visibleItemCount + lastVisibleItemPos) >= totalItemCount) {
                Log.i("LOG", "Last Item Reached!");
            }
        }
    });

我也有同样的问题。我试过了，而且成功了。我正在分享我的xml和java代码。希望这能帮助到一些人。

这是xml文件

<?xml version="1.0" encoding="utf-8"?>

< NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/iv_thumbnail"
            android:layout_width="match_parent"
            android:layout_height="200dp" />

        <TextView
            android:id="@+id/tv_description"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Description" />

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Buy" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Reviews" />
        <android.support.v7.widget.RecyclerView
            android:id="@+id/rc_reviews"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        </android.support.v7.widget.RecyclerView>

    </LinearLayout>
</NestedScrollView >

下面是相关的java代码。这招很管用。

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setNestedScrollingEnabled(false);

新的Android支持库23.2解决了这个问题，你现在可以将wrap_content设置为RecyclerView的高度并正确工作。

Android支持库23.2

试试这个。很晚的回答，但肯定对将来的任何人都有帮助。

将ScrollView更改为NestedScrollView: < android.support.v4.widget.NestedScrollView > < android.support.v7.widget.RecyclerView … ．.． /> < / android.support.v4.widget.NestedScrollView > 在你的UI代码中，为Recyclerview更新它: recyclerView.setNestedScrollingEnabled(假); recyclerView.setHasFixedSize(假);
