Question

我有一个放置在nestedscrollview中的webview。我面临的问题是webview无法加载整个页面。而是加载页面的一部分，然后将底部空间保留为空白（白色）。

我也尝试过使用scrollview。

我得到的输出：

“我的网络视图代码”：

private ImageButton backButton;
    private WebView webView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_article);

        backButton = findViewById(R.id.backButton);
        webView=(WebView)findViewById(R.id.webView);
        webView.setWebViewClient(new MyBrowser());
//        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//            descriptionView.setText(Html.fromHtml(data, Html.FROM_HTML_MODE_COMPACT));
//        } else {
//            descriptionView.setText(Html.fromHtml(data));
//        }
        webView.getSettings().setJavaScriptEnabled(true);

        webView.loadUrl("file:///android_asset/html/test.html");

        backButton.setOnClickListener(this);
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

Answer 1

您可以将NestedScrollView放置在协调器布局中，并且必须禁用滚动行为，并且如果使用应用程序栏，还必须放置布局行为。

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:nestedScrollingEnabled="false"
app:layout_behavior="appbar_scrolling_view_behavior">
.....

Answer 2

使用

android：fillViewport =“ true”

内部滚动视图属性

Answer 3

您可以使用NestedScrollView并将此行放入Webview

 android:nestedScrollingEnabled="false"

然后检查您的xml类

像这样更新您的XML文件

我猜是因为您的HTML。我尝试了其他HTML页面。一切正常。

尝试使用以下html文件

Answer 6

这就是我这样做的方式，它也可以与最新的API一起正常工作，并且实际上是将来进行滚动（隐藏Toolbar或..）行为等的最佳方法。

您需要做的就是将您的内容放在NestedScrollView内并添加：

android:nestedScrollingEnabled="true"

到WebView：

在您的onCreate()方法中：

WebView webView = findViewById(R.id.webView);
webView.loadUrl("file:///android_asset/htmlPages/test.html");

布局：

输出：

我什至使用了AndroidX依赖关系，您可以将其替换为自己的支持库标签依赖关系。
