当我尝试滚动列表时,有时这工作不正确 - BottomSheet拦截滚动事件并隐藏.

如何重现这个:

1. 打开底部
2. 更改ViewPager的页面
3. 尝试滚动列表

结果:将隐藏BottomSheet.

这是示例代码:

编译'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 …

我尝试使用ReorderableListViewinside SingleChildScrollView，但收到错误消息：
