Vitamio库打造万能播放器(四)

接着上一篇文章 Vitamio库打造万能播放器(三)

终于到了介绍vitamio的使用了,这个库使用起来非常简单,很容易上手,只需要将前面我们创建好的VideoPlayerActivity的VideoView相关的api的包名换一下即可,无需改动其他代码如下所示:

}

修改布局文件的VideoView全路径

<io.vov.vitamio.widget.VideoViewandroid:id="@id/videoView"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_centerInParent="true"/>

修改清单文件中播放器的类名

android:name=".module.video.VitamioVideoPlayerActivity"

当然上述的所有操作都是在关联了vitamio库之后的.

最后还需要在Vitamio库的VideoView源码上增加个全屏和按比例播放直接的切换.直接加在源码最后面即可:

/*** 全屏和按比例播放间的切换*/
public void toggleFullscreen() {int layout;if (mVideoLayout == VIDEO_LAYOUT_STRETCH) {//当前是全屏播放,调用后设置为按比例播放layout = VIDEO_LAYOUT_SCALE;} else {//当前是按比例播放,调用后设置为全屏播放layout = VIDEO_LAYOUT_STRETCH;}float aspectRatio = 0;setVideoLayout(layout, aspectRatio);
}
/*** 当前的播放模式是否是全屏播放*/
public boolean isFullscreen() {return mVideoLayout == VIDEO_LAYOUT_STRETCH;
}
