Question

我想在RecyclerView（尝试并失败）或CollapsingToolbarLayout中使用WebView，但是html的组件无法滚动，这是CollapsingToolbarLayout中的Webview，时区popupWindow无法滚动。

活动xml：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

        android:layout_height="match_parent">

        <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"

            android:layout_height="wrap_content">

            <com.google.android.material.appbar.CollapsingToolbarLayout

                <androidx.appcompat.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    app:layout_collapseMode="pin" />

                android:src="@drawable/ic_fullscreen" />
        </LinearLayout>

    </LinearLayout>
</layout>

itemview以前被RecyclerView使用，所以样式看起来很糟糕。我认为RecyclerView或CoordinatorLayout花费了该事件，但是当我尝试下面的代码时，它也无法滚动。

AppBarLayout.LayoutParams layoutParams = (AppBarLayout.LayoutParams) binding.collapsing.getLayoutParams();
layoutParams.setScrollFlags(0);
binding.collapsing.setLayoutParams(layoutParams);

webview的html在下面：

<body style="margin:0;padding:0;background-color:#2c2d3b">
<div class="tradingview-widget-container">
    <div id="tradingview_49c3f"></div>
    <script type="text/javascript" src="https://s3.tradingview.com/tv.js"></script>
    <script type="text/javascript">
        new TradingView.widget({"autosize": true,"symbol": "COINBASE:BTCUSD","interval": "1","timezone": "America/New_York","theme": "Dark","style": "3","locale": "en","toolbar_bg": "#f1f3f6","enable_publishing": false,"hide_top_toolbar": true,"hide_legend": true,"withdateranges": true,"save_image": false,"container_id": "tradingview_49c3f"});
    </script>
</div>
</body>

那么如何使webview的时区可以滚动？

Answer 1

您可以尝试webview.setVerticalScrollBarEnabled(true); webview.setHorizontalScrollBarEnabled(true);

可能有帮助

Answer 2

使用NestedScrollView作为父项，并在设置适配器ViewCompat.setNestedScrollingEnabled(recyclerView, false);

之后放入此行
