BottomSheetBehavior 布局中的 Android RecyclerView

Question

问题是 BottomSheetBehavior 进行了滚动，我无法在 RecyclerView 中垂直滚动我的项目。我想先从 RecyclerView 滚动项目

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="view.activity.MyActivity">


    <!--my activity views-->

    <include layout="@layout/custom_bottom_sheet_view" />


</androidx.coordinatorlayout.widget.CoordinatorLayout>

custom_bottom_sheet_view 的代码是:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/bottom_sheet_searches"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:orientation="vertical"
    app:behavior_hideable="false"
    app:behavior_peekHeight="56dp"
    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="56dp">

        <!--view peek-->

    </RelativeLayout>

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/my_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

Answer 1

试试这个:

mRecycler.setOnTouchListener(new RecyclerView.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int action = event.getAction();
                switch (action) {
                    case MotionEvent.ACTION_DOWN:
                        // Disallow NestedScrollView to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(true);
                        break;

                    case MotionEvent.ACTION_UP:
                        // Allow NestedScrollView to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(false);
                        break;
                }

                // Handle RecyclerView touch events.
                v.onTouchEvent(event);
                return true;
            }
        });

mRecycler 是你的 RecylerView
