Android ViewPager with RecyclerView works incorrectly inside BottomSheet

Question

When I try to scroll list, sometimes this works incorrect - BottomSheet intercepts the scroll event and hides.

How to reproduce this:

1. Open Bottom Sheet
2. Change a page of ViewPager
3. Try scroll the list

Result: BottomSheet will be hidden.

Here is sample code:

compile 'com.android.support:design:23.4.0'

MainActivity.java

package com.nkdroid.bottomsheetsample;  import android.os.Bundle; import android.support.design.widget.BottomSheetBehavior; import android.support.design.widget.TabLayout; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import android.widget.TextView;  public class MainActivity         extends AppCompatActivity {      private BottomSheetBehavior behavior;      @Override     protected     void onCreate(final Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          final Button btnView = (Button) findViewById(R.id.btnView);         btnView.setOnClickListener(new View.OnClickListener()         {             @Override             public             void onClick(final View v) {                 behavior.setState(BottomSheetBehavior.STATE_EXPANDED);             }         });          final View bottomSheet = findViewById(R.id.bottom_sheet);         behavior = BottomSheetBehavior.from(bottomSheet);          final ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);         viewPager.setAdapter(new MyPagerAdapter());          final TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);         tabLayout.setupWithViewPager(viewPager);       }      private     class MyPagerAdapter             extends PagerAdapter     {         @Override         public         int getCount() {             return 15;         }          @Override         public         Object instantiateItem(final ViewGroup container, final int position) {             final RecyclerView recyclerView = new RecyclerView(MainActivity.this);              recyclerView.setLayoutManager(new LinearLayoutManager(MainActivity.this));             recyclerView.setAdapter(new ItemAdapter());              container.addView(recyclerView);             return recyclerView;         }          @Override         public         boolean isViewFromObject(final View view, final Object object) {             return view.equals(object);         }          @Override         public         void destroyItem(final ViewGroup container, final int position, final Object object) {             container.removeView((View) object);         }          @Override         public         CharSequence getPageTitle(final int position) {             return String.valueOf(position);         }     }      public     class ItemAdapter             extends RecyclerView.Adapter<ItemAdapter.ViewHolder>     {          @Override         public         ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {             return new ViewHolder(new TextView(MainActivity.this));         }          @Override         public         void onBindViewHolder(final ViewHolder holder, final int position) {         }          @Override         public         int getItemCount() {             return 100;         }          public         class ViewHolder                 extends RecyclerView.ViewHolder         {             public TextView textView;              public             ViewHolder(final View itemView) {                 super(itemView);                 textView = (TextView) itemView;             }         }     } }

Any ideas for a workaround?
