I have a Recyclerview inside Scrollview, I want to store item details of Recyclerview where scroll stopped.
I have a xml like,
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/White">
<RelativeLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/tile_view_pager"
android:layout_width="match_parent"
android:layout_height="200dp"
android:visibility="gone"
android:layout_marginRight="2dp"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/news_feed_recycler"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
I have added ScrollListener for recyclerview. But As I'm using parent Scrollview for the activity, recyclerview's ScrollListener is not getting called.
I tried changing parent scrollview to NestedScrollView then recyclerview is scrolling as a one item at once but i want scroll to be freely. Like scrolling our contacts.
Issue : When I scroll, Parent ScrollView getting scrolled and I don't have any control on my recyclerview. So It's difficult to figure out which item of recyclerview is visible once scroll stopped.
Basically I want to code without changing my XML.
I want to store item details of Recyclerview where scroll stopped.
When scroll stops, scroll state transitions into idle state. However, idle state is the state before and after scroll. Therefore you are looking for a transition into idle state after settling state.
Do it like this:
mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
boolean scrolled;
int[] displayedPositions;
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == RecyclerView.SCROLL_STATE_SETTLING) {
scrolled = true;
} else if (newState == RecyclerView.SCROLL_STATE_IDLE && scrolled) {
scrolled = false;
int[] into = new int[//number of spans];
displayedPositions = ((StaggeredGridLayoutManager) recyclerView.getLayoutManager()).findFirstCompletelyVisibleItemPositions(into)
}
}
}
private int overallXScrol = 0;
//...
mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
overallXScroll = overallXScroll + dx;
Log.i("check","overall->" + overallXScroll);
}
});
try NestedScrollView instead scrollview like below
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/White">
<RelativeLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/tile_view_pager"
android:layout_width="match_parent"
android:layout_height="200dp"
android:visibility="gone"
android:layout_marginRight="2dp"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/news_feed_recycler"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
I found the solution. Just we need to change layout. I'm using CoordinatorLayout as a parent view. And Now I'm able to use onScrollListener of recyclerview.
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/White">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="#+id/tile_view_pager"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_marginEnd="2dp"
android:visibility="gone"/>
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>

I have an AppBar and RecyclerView in CoordiantorLayout. SwipeToRefresh has to be fullscreen but RecyclerView not scrolling down then.
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="128dp"/>
</com.google.android.material.appbar.AppBarLayout>
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
How to add fullscreen pull to refresh in Coordinator layout without a library.
You can disable swipe refresh layout when AppBar isn't fully expanded and enable it if it is fully expanded.
vAppBar.addOnOffsetChangedListener(AppBarLayout.OnOffsetChangedListener { _, verticalOffset ->
vSwipeRefresh.isEnabled = verticalOffset == 0
})
I add swipetorefresh top level like answer above. And I fix my scroll up issue with code below. Thanks to mohammadReza :)
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener(){
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
int topRowVerticalPosition =
(recyclerView == null || recyclerView.getChildCount() == 0) ? 0 : recyclerView.getChildAt(0).getTop();
swipeRefreshLayout.setEnabled(topRowVerticalPosition >= 0);
}
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
});
try to set SwipeRefreshLayout as root parent like this :
<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"

I'm trying to implement hide/show SearchView on scroll feature inside a SwipeRefreshLayout.

I have a fragment which renders a recycleview with an floating action button. The problem is that when the list is empty, the fab keeps on the right top, when the list has few items, the fab keeps below the list but not at the bottom, and it only keeps totally at the bottom when the list fill the screen with items. Could somebody help me please? Bellow is my code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.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"
tools:context="com.app.juninho.financeapp.activity.FuncionarioActivity">
<android.support.v7.widget.RecyclerView
android:id="#+id/funcionario_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/btn_add_func"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right|end"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_margin="16dp"
android:src="#drawable/ic_menu_send"
app:layout_behavior="com.app.juninho.financeapp.utils.ScrollAwareFABBehavior" />
</android.support.design.widget.CoordinatorLayout>
if the list is empty, fab keeps at the top, which is wrong:
if the list has a few items, fab doesn't keep totally at the bottom:
Here is the correct way, fab is at the bottom:
Using RelativeLayout it seems to work, but its too at the right/bottom corner:
The problem is your FAB attribute: app:layout_behavior="com.app.juninho.financeapp.utils.ScrollAwareFABBehavior".
#. You don't need to add this with your FAB. Just remove this attribute and add attribute app:layout_anchor="#id/funcionario_recycler_view" and app:layout_anchorGravity="bottom|right|end" to FAB to anchor it with RecyclerView.
Update your layout as below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.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"
tools:context="com.app.juninho.financeapp.activity.FuncionarioActivity">
<android.support.v7.widget.RecyclerView
android:id="#+id/funcionario_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/btn_add_func"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right|end"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_margin="16dp"
android:src="#drawable/ic_menu_send"
app:layout_anchor="#id/funcionario_recycler_view"
app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>
#. If you want to hide/show FAB when scrolling RecyclerView, then you can do it pragmatically in your java code as below:
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.funcionario_recycler_view);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.btn_add_func);
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener()
{
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy)
{
if (dy > 0 ||dy<0 && fab.isShown())
{
fab.hide();
}
}
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState)
{
if (newState == RecyclerView.SCROLL_STATE_IDLE)
{
fab.show();
}
super.onScrollStateChanged(recyclerView, newState);
}
});
Hope this will help~
I'm using RecyclerView inside NestedScrollView. Also i set setNestedScrollingEnabled to false for recyclerview
to support lower API
ViewCompat.setNestedScrollingEnabled(mRecyclerView, false);
Now! When user scrolled the view every thing seems okay, but!!! views in recyclerview does not recycled!!! and Heap size grows swiftly!!
Update:
RecyclerView layout manager is StaggeredLayoutManager

P.s : I've set load more to scroll view, because recyclerview do it continuously and none stoppable!
Any help is appreciated
This is because we have a recycler view which has scroll behaviour inside a scroll view. (scroll inside a scroll)
I think the best way to resolve this issue is to your profileCardview as a header in your recycler view and then remove the nested scroll view.
If it were a listview then it was as simple as listView.addHeaderView(profileCardView) but for the Recycler view there is no addheadview equivalent. Hence you could refer the below link to change your implementation.
Is there an addHeaderView equivalent for RecyclerView?
For a RecyclerView or ListView the height should be constant, because if it will not a constant size then how it will manage the maximum number of visible rows in memory. Try by changing RecyclerView attribute android:layout_height="match_parent" or a fixed height(e.g. "300dp" - as needed), instead of "wrap_content". It should improve your memory management.
Please help me with the following situation.
I am developing an application where in one page I have a Linearlayout with a background image and RecyclerView with list of names.What I need is when i scroll up the RecyclerView I need the LinearLayout above also to move up so that the list in the recyclerView does not go under the LinearLayout above and when I scroll down the RecyclerView I need the LinearLayout above to scroll down so that we could see the image fully.
What i have done already is I used the setOnScrollListener of recyclerview and in the onScrolled() function I am getting the scrolling down and scrolling up event.But now i am stuck how to proceed further.
Below is the layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"

android:layout_height="0dp"
android:layout_weight="2"
android:scrollbars="vertical" />
</LinearLayout>
</ScrollView>
</android.support.v7.widget.CardView>
</RelativeLayout>
Here is the code, i used in corresponding java class:
#InjectView(R.id.scrollview)
ScrollView scrollview;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shoplist);
ButterKnife.inject(this);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setTitle("ShopList");
scrollview.setVerticalScrollBarEnabled(true);
lm=new LinearLayoutManager(ShopListActivity.this);
recyclerView.setLayoutManager(lm);
firstVisibleInListview = lm.findFirstVisibleItemPosition();
adapter = new RecyclerViewAdapter(ShopListActivity.this, getData());
recyclerView.setAdapter(adapter);
recyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(ShopListActivity.this, new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
Intent intent1 = new Intent(ShopListActivity.this, ShopProductListActivity.class);
intent1.putExtra("position", String.valueOf(position));
intent1.putExtra("shopname", it.get(position).getTitle());
intent1.putExtra("shopimage", String.valueOf(it.get(position).getImgIcon()));
intent1.putExtra("subcategory", subcategory);
startActivity(intent1);
}
})
);
recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int currentFirstVisible = lm.findFirstVisibleItemPosition();
if(currentFirstVisible > firstVisibleInListview){
Toast.makeText(getBaseContext(),"Scrolled up ",Toast.LENGTH_SHORT).show();
scrollview.fullScroll(ScrollView.FOCUS_UP);
}
else
Toast.makeText(getBaseContext(),"Scrolled down ",Toast.LENGTH_SHORT).show();
firstVisibleInListview = currentFirstVisible;
}
});
}
so if I understand your question completely, you some View that should scroll with
RcyclerView.
if so in this situation you should delete your ScrollView cause RecyclerView have that within itself. what I write here is step by step guide to put a header( not sticky) in top of your RecyclerView so they would scroll together:
1- first you need to create a layout containing your header in my case i had an image for header so it looked like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#mipmap/winter"/>
</LinearLayout>
let's call this header_layout
2- you need to implement another method of RecyclerAdapter called getItemViewType it's output would be in as second parameter onCreateViewHolder(ViewGroup parent,int viewType) here you inflate the layout for each kind of view you need( for me these two look like this) :
#Override
public int getItemViewType(int position){
if(position == 0){
return 0;
} else {
return 1;
}
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView;
if(viewType==1){
itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.report_row_layout, parent, false);
} else {
itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.report_header_layout, parent, false);
}
return new MyViewHolder(itemView);
}
note that my first position (header) differs and other are the same you could have multiple views for multiple positions.
3- you should change your onBindViewHolder if needed in my case I needed to make it do nothing for my first position
4- remove your ScrollView and implement the layouts in positions and your main layout should look like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<include layout="#layout/toolbar"
android:id="#+id/toolbar" />
<android.support.v7.widget.CardView
android:id="#+id/cardview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar"
android:layout_margin="8dp"
card_view:cardBackgroundColor="#android:color/white"
card_view:cardCornerRadius="8dp">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.CardView>
</RelativeLayout>
I don't know what your CardView is doing but delete it if you think it's not needed. if you need you can make your header a LinearLayout or anything else.
hope this helps.
