一.在build.gradle中引入谷歌VR的SDK依赖 compile 'com.google.vr:sdk-videowidget:1.10.0' 二.注意支持的最小SDK minSdkVersion 19 targetSdkVersion 25 三.界面布局文件

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Android开发VR360度全景视频" />

<com.google.vr.sdk.widgets.video.VrVideoView
    android:id="@+id/vr_video_view"
    android:layout_width="match_parent"
    android:layout_height="250dp"></com.google.vr.sdk.widgets.video.VrVideoView>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <ImageButton
        android:id="@+id/play_toggle"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@android:color/transparent"
        android:paddingStart="0dp"
        android:src="@drawable/pause" />

    <SeekBar
        android:id="@+id/seek_bar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="0dp"
        android:layout_height="32dp"
        android:layout_weight="8" />

    <ImageButton
        android:id="@+id/volume_toggle"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@android:color/transparent"
        android:paddingStart="0dp"
        android:paddingTop="4dp"
        android:src="@drawable/volume_on" />
</LinearLayout>
