TextView below NestedScrollView with height wrap_content not visible

Question

Below is the layout file of the bottom sheet. I have a TextView below the nested scroll view. When the content is large, the TextView below the NestedScrollView is not visible. If content of NestedScrollView is small it is visible. I am not getting what's causing this.

Here is my layout file:

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/bottom_sheet_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            app:popupTheme="@style/AppTheme.PopupOverlay"
            app:title="My Title">

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="end"
                android:background="?attr/selectableItemBackgroundBorderless"
                android:onClick="@{() -> handler.hideBottomSheet()}"
                android:src="@drawable/ic_keyboard_arrow_down_black_24dp" />

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

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin">

            <RadioGroup
                android:id="@+id/selection_mode"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dp"
                android:checkedButton="@+id/mode_1"
                android:gravity="center"
                android:orientation="horizontal">

                <RadioButton
                    android:id="@+id/mode_1"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/mode_1" />

                <RadioButton
                    android:id="@+id/mode_2"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/mode_2" />

            </RadioGroup>

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

                <LinearLayout
                    android:id="@+id/list_container"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical" />

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

            <TextView
                android:id="@+id/list_description"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="20dp"
                android:layout_marginTop="10dp"
                android:gravity="center"
                android:text="This text is not visible. I dunno why! :/" />

        </LinearLayout>

    </LinearLayout>
</FrameLayout>

list_container LinerLayout is inflated on Runtime. There are some reasons I am not using RecyclerView or ListView. This is fairly small, Just a little scrolling sometime.

But the TextView list_description is not being displayed when list_container is large (needs scrolling).

I am not getting it what's going wrong.

Try using android:layout_weight on your NestedScrollView.

In your case, replace the header of your NestedScrollView with:

<android.support.v4.widget.NestedScrollView
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"

Hope that helps =]
