recycler-adapter

I am working on an app where I am trying to populate a list using RecyclerView and recycler adapter as well. But when I scroll through the list quickly sometimes values on the list item shuffles among list items. Is there a known fix for this? adding this in the adapter solved the problem @Override public int getItemViewType(int position) { return position; } Just Override these methods in your adapter class: @Override public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { return position; } This link will help you to get the understanding

I have this problem - just for testing purposes I added ParseFile to one of ParseObject from received list. Instead of showing it only in that row it shows every 4-5 rows, sometimes more, sometimes less. I supspect that recycling view have something to do with this. Strangely, other data (deleted from this example) works fine with position variable. @Override public void onBindViewHolder(ViewHolder holder, int position) { if(parseList.get(position).get("logo") != null){ ParseFile image = (ParseFile) parseList.get(position).get("logo"); String url = image.getUrl(); Glide.with(context) .load(url

I'm contributing to open source library and got lint error "Do not treat position as fixed; only use immediately and call holder.getAdapterPosition() to look it up later" for this code: @Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { mAdapter.onBindViewHolder(holder, position); if (!isFirstOnly || position > mLastPosition) { for (Animator anim : getAnimators(holder.itemView)) { anim.setDuration(mDuration).start(); anim.setInterpolator(mInterpolator); } mLastPosition = position; } else { ViewHelper.clear(holder.itemView); } } I've checked that it is

I have created a very simple project, displaying 28 images with StaggeredGridLayoutManager by recyclerview. but as I scroll the recyclerview it moves items for example from left to right or swap the column of left and right. codes: import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.os.Bundle; import android.support.v7.widget.RecyclerView; import android.support.v7.widget.StaggeredGridLayoutManager; public class MainActivity extends Activity { String mImageDir; private RecyclerView mRecyclerView; private StaggeredGridLayoutManager mLayoutManager;

I'm trying to refresh specific item in RecyclerView . Story: Whenever user clicks on item, it shows AlertDialog . User can type some text by clicking ok button. I want to show this text in this item and show invisible ImageView - declared in XML and adapter ViewHolder - I used this function in AlertDialog Positive Button to update the item: private void updateListItem(int position) { View view = layoutManager.findViewByPosition(position); ImageView medicineSelected = (ImageView) view.findViewById(R.id.medicine_selected); medicineSelected.setVisibility(View.VISIBLE); TextView orderQuantity =

In RecyclerView , I want to set an empty view to be shown when the adapter is empty. Is there an equivalent of ListView.setEmptyView() ? With the new data binding feature you can also achieve this in your layout directly: <TextView android:text="No data to display." android:visibility="@{dataset.size() > 0 ? View.GONE : View.VISIBLE}" /> In that case you just need to add a variable and an import to the data section of your XML: <data> <import type="android.view.View"/> <variable name="dataset" type="java.util.List<java.lang.String>" /> </data> Here's a class similar to @dragon born's, but more

Our question is how to show Parent and Child data from two SQLite DB tables? We have two tables that are added to two ArrayLists childList and parentList . Here are the Model Class's for each class ModelParent { var idD:Int = 0 var dept:String = "" var fkD:Int = 0 var children: List<ModelChild> = mutableListOf() //var children: ArrayList<ModelChild>? = null //var children: List<ModelChild> by Delegates.notNull() constructor (children: List<ModelParent>) : this() companion object { var globalVar = 1 } } class ModelChild { var idI:Int = 0 var item:String = "" var fkI:Int = 0 } We have two
