How to Apply Shimmer Effect android swipeProgress?

How to connect my rssfragment to Apply Shimmer Effect swipeProgress. I need to show you a shimmer layout when rssfragment is in progress. I tried and lyt_shimmer did not show me
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
refreshItems();
}
});
I need to include_shimmer_recipes_list when refreshing

This layout should come when I have data progress. If anyone knows you please help me

You can use ShimmerFrameLayout Library from Facebook.
If you want to show the Shimmer effect while your RecyclerView Items are loading then you can follow this link to implement it in your Project.

So what I understand from your query that you need to show the shimmer effect layout once the user swipes to the screen and progress starts showing.
You need to implement the onRefresh method of OnRefreshListener using the SwipeRefreshLayout object.
When the user swipes to refresh the screen there will be a callback in the above method from that you can hide your main layout and show shimmer effect layout and once data refreshes via remote or local data source you can hide the shimmer effect layout and show the main content layout again in the same RSS fragment.
Here's the sample implementation, maybe that helps you :
val listener = object : SwipeRefreshLayout.OnRefreshListener {
override fun onRefresh() {
swipeRefreshLayout.visibility = View.GONE
showShimmerAnimation()
}
}
swipeRefreshLayout.setOnRefreshListener(listener)
fun showShimmerAnimation() {
shimmer_view_container.apply {
visibility = View.VISIBLE
startAnimation()
}
}
fun hideShimmerAnimation() {
shimmer_view_container.apply {
visibility = View.GOE
stopAnimation()
}
}
fun onDataLoaded() {
hideShimmerAnimation()
swipeRefreshLayout.visibility = View.VISIBLE
}

Any help would be highly appreciated. Although this question has already been asked. I have checked those. Those are not valid in my case like
Returning zero from getIemCount method
Not passing layout manager

As per the official documentation of the Swipe refresh layout
"This layout should be made the parent of the view that will be refreshed as a result of the gesture and can only support one direct child."
So consider re-structuring your layout so that the RecyclerView is the only child under Swipe refresh layout.

grid view items not scrolling down to up (repeating the items) and when i am loading data from server in android?

I have a grid view and data updated in grid view using api calls and grid item loads a image from url using picasso library all are perfect but when i am scrolling down to up the grid items not scrolled and repeating the items(up to down scrolling was perfect).

To avoid the unexpected behaviour , provide the implementations of
#Override
public Object getItem(int position) {
return mProducts.get(position);
}
#Override
public long getItemId(int position) {
//return position; or better to provide some unique id
// as there is one in your code, product id
return mProducts.get(position).prod_id;
}
Note : remove notifyDataSetChanged(); in getView because it will trigger the adapter to refresh all view while they are under creating which can cause this behaviour.

It's not possible to make a scrollable view inside a scrollable view. But as a work around this, and only in case that this listviews doesn't take much memory if all views are loaded.
you can use this
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class NonScrollableListView extends ListView {
public NonScrollableListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Do not use the highest two bits of Integer.MAX_VALUE because they are
// reserved for the MeasureSpec mode
int heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightSpec);
getLayoutParams().height = getMeasuredHeight();
}
}
Again, it's not good to use this workaround
you will use this non Scrollable listview in the child.xml layout by adding it as a customized UI component
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.youpackage.uiutils.NonScrollableListView
android:id="#+id/non_scrollable_listview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>

You can ExpandableListView in place of making custom view also for data handling you can use ExpandableListAdapter.
