Android UniversalVideoView实现视频播放器

本文实例为大家分享了Android UniversalVideoView实现视频播放器的具体代码，供大家参考，具体内容如下

1.添加依赖 app下的 build.gradle

dependencies {
 
    ......
 
    compile 'com.linsea:universalvideoview:1.1.0@aar'
}

2.XML布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
 
 
    <FrameLayout
        android:id="@+id/video_layout"
        android:layout_width="fill_parent"
        android:layout_height="200dp"
        android:background="@android:color/black">
 
        <com.universalvideoview.UniversalVideoView
            android:id="@+id/videoView"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="center"
            app:uvv_autoRotation="true"
            app:uvv_fitXY="false" />
 
        <com.universalvideoview.UniversalMediaController
            android:id="@+id/media_controller"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            app:uvv_scalable="true" />
    </FrameLayout>
 
    <LinearLayout
        android:id="@+id/bottom_layout"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="vertical">
 
        <Button
            android:id="@+id/start"
            android:layout_margin="5dp"
            android:layout_width="fill_parent"
            android:layout_height="50dp"
            android:gravity="center"
            android:text="start" />
 
        <TextView
            android:id="@+id/introduction"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:gravity="center"
            android:text="this is video introduciton ......"
            android:background="@color/uvv_gray" />
    </LinearLayout>
</LinearLayout>
