I'm creating an app that has swipe-to-refresh feature with Material 3 (Material You) design. But when scrolling the content under the SwipeRefreshLayout, the app bar doesn't lift properly as expected. It works correctly when the SwipeRefreshLayout is refreshing.
activity-main.xml
<?xml version="1.0" encoding="utf-8"?>

app:titleCentered="true"/>
</com.google.android.material.appbar.AppBarLayout>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout

android:layout_height="wrap_content"
android:text="Long lorem ipsum text..."/>
</androidx.core.widget.NestedScrollView>
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
MainActivity.java
package com.fourbits.appbarandswiperefresh;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I tried to change my SwipeRefreshLayout androidx dependency version from 1.2.0-alpha01 to 1.1.0, but the problem still exists.
I expect that the app bar will lift properly when the content is scrolled under the SwipeRefreshLayout.
Using app:liftOnScrollTargetViewId="@id/nestedScroll"
on app bar layout solves it.
