Recycler視圖項目不滾動？

Question

我正在處理Recycler視圖，在這里我將三個回收站視圖水平放置在一個布局中。問題是第二個和第三個回收站視圖項目顯示但是無法滾動，即使使用嵌套滾動內部並因此附加xml.Kindly建議我如何滾動第二和第三個回收者視圖。

Answer 1

在您初始化回收站視圖的位置發布您的Java代碼。 此外，嘗試從嵌套滾動視圖中刪除回收器視圖（您可以放置​​它們而不嵌套滾動視圖）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rightLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">
    <LinearLayout
        android:id="@+id/lay1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="#ff0000">
        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerViewmonth"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
            <LinearLayout
                android:id="@+id/lay2"
                android:layout_width="fill_parent"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:background="#00ff00">
                <android.support.v7.widget.RecyclerView
                    android:id="@+id/recyclerViewdate"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" />
            </LinearLayout>
    <LinearLayout
        android:id="@+id/lay3"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="#0000ff">
        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerViewyear"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
</LinearLayout>

Answer 2

將所有Recycler視圖保留在嵌套滾動視圖中。

Answer 3

將父布局高度更改為match_parent。 喜歡

<RelativeLayout
    android:id="@+id/layout_bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/color_bottom_sheet"
    android:elevation="@dimen/z_bottom_sheet"
    app:behavior_hideable="true"
    app:behavior_peekHeight="80dp"
    app:layout_behavior="@string/string_bottom_sheet_behavior">


</RelativeLayout>
