<android.support.design.widget.coordinatorlayout 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.support.v4.widget.nestedscrollview     android:layout_width="match_parent"     android:layout_height="match_parent"     app:layout_behavior="@string/appbar_scrolling_view_behavior">      <linearlayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical"         android:paddingbottom="98dp"         android:paddingleft="24dp"         android:paddingright="24dp">          <android.support.v7.widget.appcompattextview             android:id="@+id/detail_expense_reason_trim"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:singleline="false"             android:textcolor="@color/add_new_expense_text_color" />          <android.support.v7.widget.appcompattextview             android:id="@+id/detail_expense_reason"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:singleline="false"             android:textcolor="@color/add_new_expense_text_color"             android:visibility="gone" />     </linearlayout>  </android.support.v4.widget.nestedscrollview>  <android.support.design.widget.appbarlayout     android:layout_width="match_parent"     android:layout_height="wrap_content">      <android.support.v7.widget.toolbar         android:id="@+id/detail_expense_toolbar"         android:layout_width="match_parent"         android:layout_height="?attr/actionbarsize"         android:theme="@style/themeoverlay.appcompat.dark.actionbar"         app:layout_scrollflags="scroll|enteralways"         app:popuptheme="@style/themeoverlay.appcompat.light" /> </android.support.design.widget.appbarlayout> 

 @injectview(r.id.detail_expense_reason) appcompattextview originalreason;  @injectview(r.id.detail_expense_reason_trim) appcompattextview trimreason;  @injectview(r.id.detail_expense_container) linearlayout expensecontainer;

// handle event

public void onclick() {     if (originalreason.getvisibility() == view.visible) {         originalreason.setvisibility(view.gone);         trimreason.setvisibility(view.visible);     } else {         originalreason.setvisibility(view.visible);         trimreason.setvisibility(view.gone);     }  }

it bug of nestedscrollview, detail of bug can found in here: issue. problem mscroller.isfinished() in onintercepttouchevent(motionevent ev) not return true after fling operation (even if fling stopped). therefore touch event intercepted.

this bug have been reported while, still have not been fixed. have created own version of bug fix problem. implemented own nestedscrollview, copied code nestedscrollview , having following amendments:

public class nestedscrollview extends framelayout implements nestedscrollingparent, nestedscrollingchild {     ...     private void initscrollview() {         ...         // replace line:         // mscroller = new scrollercompat(getcontext(), null);         mscroller = scrollercompat.create(getcontext(), null);         ...     }      @override     public boolean onintercepttouchevent(motionevent ev) {         ...         switch (action & motioneventcompat.action_mask) {             ...             case motionevent.action_down: {                 ...                 // replace line:                 // misbeingdragged = !mscroller.isfinished();                 misbeingdragged = false;                 ...             }         }     }    }

and nestedscrollview should have same behaviour original one.
