两个 Web 视图在 Android 中垂直对齐

Question

我是Android编程的新手，我想显示两个Web视图，第二个在第一个垂直下方对齐。我希望它们同时显示。我已经尝试了有关该主题的不同帖子，但示例代码似乎显示在不同的活动或窗口中。

这是我开发的内容，但我需要您关于如何解决这个问题的想法

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>

这是连接包含两个 Web 视图的activity_main.xml的示例 java 文件主要活动.java

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView1 = (WebView) findViewById(R.id.webView);

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。
