Not able show bottom items in recyclerView-CodePudding

I am using recyclerview in my project but bottom items are not displayed in recyclerview. I tried ScrollView but my app is crashing it shows java.lang.IllegalStateException: ScrollView can host only one direct child this error.

CodePudding user response：

I think you use the recyclerview as parent layout that this work is wrong, because recyclerview in android just get a adapter that it, and you most use the container layout like scrollbars for show another layout inside it.

CodePudding user response：

You have added more than one ViewGroup as a child of your ScrollView. ScrollView must contain at most one child in order to properly calculate the height of the view.

Below sample code is wrong:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        ....
        ....
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        ....
        ....
    </LinearLayout>
</ScrollView>

In order to solve the problem, you can use the below sample code:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <!-- here add your views -->
        ....
        ....
    </LinearLayout>
</ScrollView>
