VideoView est un composant personnalisé disponible sur Android, c'est la combinaison de MediaPlayer et de SurfaceView qui vous aide à lire une vidéo plus facilement.
Lorsque vous utilisez VideoView, vous pouvez utiliser MediaController, cela est disponible dans Android qui sert à contrôler des médias (par exemple, le démarrage, l'arrêt, le rembobinage, la pause ...)
Si vous localisez VideoView et MediaController dans FrameLayout, vous pouvez obtenir l'interface comme ci- dessous:
Maintenant, nous pouvons voir un exemple avec VideoView et MediaController situé à la surface de la vidéo. Vous pouvez prévisualiser les images dans l'exemple ci- dessous:
Créez un nouveau projet nommé AndroidVideoView:
- File > New > New Project > Empty Activity
- Name: AndroidVideoView
- Package name: org.o7planning.androidvideoview
- Language: Java
Créez un dossier raw afin de comprendre des fichiers video.
Copiez & Collez des fichiers video mp4 dans le dossier raw:
If you want to play a video from a URL you need to allow the application to use the network, add the following XML code to AndroidManifest.xml:
<uses-permission android:name="android.permission.INTERNET"/>
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.o7planning.androidvideoview">
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Design the Interface:
If you are interested in the steps to design the interface of this application, please see the appendix at the end of the article.

Quelques remarques de l'utilisation du code:
Imaginez quand vous utilisez setAnchorView() pour attacher MediaController à VideoView:
Interface design of the application:
Set ID, Text for components on the interface:
