可以在 android 中将一个视频视图放在另一个视频视图上吗？

Question

我的问题是，在 android 中，一个视频视图应该在整个屏幕上播放视频，另一个视频视图应该在屏幕角落播放另一个小尺寸视频。 为此，它需要两个视频视图同时播放视频。在android中可以实现吗？

正如我所见，我们可以在下面的链接中同时播放两个视频。但是这里的两个视频视图没有重叠。 How to play multiple video files simultaneously in one layout side by side in different view in Android

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/parentLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
>

<VideoView
    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

<VideoView
    android:id="@+id/videoView1"
    android:layout_width="300dp"
    android:layout_height="200dp"
    android:layout_centerInParent="true"/>

是的，可以同时播放多个视频。您可以使用 FrameLayout 或 RelativeLayout 来放置 VideoView。

示例源代码（示例使用资产文件夹中的视频文件）

activity_video_player.xml

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

<VideoView
    android:layout_weight="1"
    android:id="@+id/videoview2"
    android:layout_width="200dp"
    android:layout_height="150dp"/>

<VideoView
    android:id="@+id/videoview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>
</FrameLayout>
