我已经构建了一个显示许可协议(protocol)的示例 Webview 页面。它在 android Kitkat 上运行得很好，文本适合页面，您可以向下滚动。

但是当我尝试在 android 9 或 10 上运行时，文本无法正确显示，如下面的屏幕截图所示。

我做错了什么？

更新:此行导致此问题:

            "<FONT COLOR=\"#0000ff\"><FONT SIZE=2><U>www.capturedoc.com</U></FONT></FONT></A><FONT SIZE=2>.</FONT></P>\n" +

当前结果(Android 9)

预期结果(Android Kitkat)

content_license_agreement

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context=".copyright.LicenseAgreementActivity"
tools:showIn="@layout/activity_license_agreement">

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="20dp"
    tools:layout_editor_absoluteX="30dp"
    tools:layout_editor_absoluteY="30dp">

    <WebView
        android:id="@+id/lic_agreement"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

 </LinearLayout>

 </androidx.constraintlayout.widget.ConstraintLayout>

最佳答案

出于某种奇怪的原因，标签 <FONT COLOR="#0000ff">...</FONT>无法正常工作尝试使用以下内容进行更改。它适用于 Android API 29。

"       <FONT COLOR=\"blue\">" +
"           <FONT SIZE=2>" +
"               <U>www.capturedoc.com</U>" +
"           </FONT>" +
"       </FONT>" +

我还删除了 content_license_agreement.xml 中的 ConstraintLayout，现在如下所示:

<LinearLayout android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="20dp"
    android:padding="20dp"
    xmlns:android="http://schemas.android.com/apk/res/android">

        <WebView

            android:id="@+id/lic_agreement"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

</LinearLayout>

最后，这是最终的 Activity :
