Answer 1

忘了说了,需要修改视频地址
在android4.1中是可以全屏的

Answer 2

还有一个文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.testvideoview"
    android:versionCode="1"
    android:versionName="1.0" >    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="17" />    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.testvideoview.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />
