<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="250dp" android:orientation="vertical" android:padding="8dp" android:id="@+id/list_item">  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content">      <imageview         android:id="@+id/food_picture"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:adjustviewbounds="true"         android:src="@drawable/blank2" />   </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="vertical">     <linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal">         <textview             android:id="@+id/title"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:gravity="center"             android:text="@string/test_name_food"             android:textappearance="?android:attr/textappearancemedium"             android:textcolor="#242424"             android:paddingtop="4dp" />     </linearlayout>      <linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="horizontal"         android:paddingleft="8dp"         android:paddingbottom="8dp"         android:paddingright="8dp"         android:paddingtop="4dp">         <textview             android:id="@+id/ingr_count"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:text="@string/test_name_ingr"             android:textappearance="?android:attr/textappearancesmall"             android:layout_weight="1"             android:textalignment="center"             android:layout_gravity="center_vertical"             android:gravity="center" />         <!--                 <linearlayout                     android:layout_width="match_parent"                     android:layout_height="match_parent"                     android:orientation="horizontal"                     android:layout_weight="33">                      <imageview                         android:id="@+id/ic_ingredient"                         android:layout_width="24dp"                         android:layout_height="24dp"                         android:src="@drawable/ic_ingredient"                         android:layout_gravity="center_vertical"                         android:layout_weight="1"                         android:paddingright="8dp" />                     <imageview                         android:id="@+id/ic_time"                         android:layout_width="24dp"                         android:layout_height="24dp"                         android:src="@drawable/ic_time"                         android:layout_gravity="center_vertical|right"                         android:layout_weight="1"                         android:paddingleft="8dp" />         </linearlayout>         -->            <textview             android:id="@+id/look"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:text="Просмотреть"             android:textappearance="?android:attr/textappearancesmall"             android:layout_gravity="center"             android:textalignment="center"             android:gravity="center"             android:textcolor="#4caf50"             android:textstyle="bold"             android:typeface="normal"             android:layout_weight="1" />      </linearlayout>   </linearlayout> 

and additional.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="300dp" android:orientation="vertical" android:id="@+id/ad_test2" android:background="@drawable/blank2">  <imageview     android:layout_width="match_parent"     android:layout_height="match_parent"     android:src="@drawable/blank2"     android:id="@+id/blank_holder"/> 

here's gist of recycleradapter.class https://gist.github.com/burnix/d0b32f0dc4b525ec3aa7 if need, suppose, there problem in 1 of layouts.

so how can solve issue?

p.s. if layouts have same height, lags don't disappear.

i upset stackoverflow. seems, pre-juniors surfing here answering questions like:"why have npe in onclick?"...

here solution. hope useful: solve lags in recycler: in adapter:

   picasso.with(context)           .load(...)           .tag("resume_tag")           .into(...); 

in endlessscrolllistener class

   @override public void onscrollstatechanged(recyclerview recyclerview, int newstate) {     super.onscrollstatechanged(recyclerview, newstate);     final picasso picasso = picasso.with(context);     if (newstate == recyclerview.scroll_state_idle) {         picasso.resumetag("resume_tag");     } else {         picasso.pausetag("resume_tag");     }  } 

in class, calls recyclerview:

    if (offset == 0)                             adapter.notifyitemrangeinserted(0, fooddatalist.size());  //or adapter.notifydatasetchanged()                         else                             adapter.notifyitemrangechanged(fooddatalist.size() - jsonarray.length(), fooddatalist.size());
