How Can I make this LinearLayout scroll? I want these text views in LinearLayout to be over RecyclerView and hide up when scrolling. I've read that I will get it by adding the following app:layout_behavior="@string/appbar_scrolling_view_behavior"
But it's not working.
XML:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/gradientbackground"
android:screenOrientation="portrait" >
<androidx.recyclerview.widget.RecyclerView
android:layout_marginTop="100dp"
android:id="@+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="text2" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="text2" />
</LinearLayout>
</androidx.core.widget.NestedScrollView>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="@+id/nav_view"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="@drawable/bottom_navigation_background"
android:elevation="0dp"
android:outlineProvider="none"
app:itemIconTint="@color/bottom_navigation_colors"
app:labelVisibilityMode="selected"
app:layout_anchor="@+id/recyclerview"
app:layout_anchorGravity="bottom|center"
app:layout_behavior="@string/hide_bottom_view_on_scroll_behavior"
app:layout_scrollFlags="scroll|enterAlways"
app:menu="@menu/bottom_nav_menu" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
You can try to set a coordinate reference and hide LinearLayout when you scroll past or over that particular reference point.
You can get a view's Y coordinate by using this as a reference:
private View mIamYourView;
mIamYourView.getY(); // You can opt this as int, since it's what's going to be needed, I think this returns a double or a float.
Now you can use your Scrollview's Y coordinate and see if it's gone past or has seen your reference point like so:
private ScrollView mYourScrollView;
if(mScrollView.getScrollY() >= mIamYourView.getY()){
mIamYourview.setVisiblity(VIEW.GONE);
}
Pls try your RecyclerView inside NestedScrollView
