android 随手记 videoview循环播放网络视频和mediaplayer+sufaceview播放网络视频

1：videoview循环播放视频

1》xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >    <VideoView
        android:id="@+id/vv_player"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"/></RelativeLayout>

2，mediaplayer+sufaceview播放视频

最后因为播放是网络视频千万不要忘了添加访问网络权限，

<uses-permission android:name=”android.permission.INTERNET” />
    <uses-permission android:name=”android.permission.READ_PHONE_STATE” />
    <uses-permission android:name=”android.permission.READ_LOGS” />
    <uses-permission android:name=”android.permission.WRITE_EXTERNAL_STORAGE” />
    <uses-permission android:name=”android.permission.WRITE_SETTINGS” />
    <uses-permission android:name=”android.permission.WAKE_LOCK” />
