java - Android 中两个垂直对齐的 WebView

Question

我是 Android 编程新手，我想显示两个 webview，第二个 webview 垂直对齐在第一个 webview 下方。我希望它们同时显示。我已经尝试过有关该主题的不同帖子，但示例代码似乎显示在不同的 Activity 或窗口中。

这是我开发的内容，但我需要您的想法来解决这个问题

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
>

    <WebView
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/webView2"
        />

        <WebView
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/webView2"
            />
 </LinearLayout>

这是连接 Activity_main.xml 的示例 Java 文件，其中包含两个 Web View MainActivity.java

Answer 1

在 LinearLayout 中将方向设置为垂直而不是水平。还可以使用权重属性来正确对齐布局。
