一、播放本地视频文件
根据文件路径在浏览器中播放，可用于视频预览等场景
效果：
用浏览器播放本地视频
文件路径例子：
/storage/emulated/0/Android/data/com.custom.jfrb/files/Movies/1697687179497.mp4
File file = new File("文件路径");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.putExtra("oneshot", 0);
intent.putExtra("configchange", 0);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);Uri contentUri = FileProvider.getUriForFile(UploadVideoActivity.this, getContext().getPackageName() + ".provider", file);intent.setDataAndType(contentUri, "video/*");
} else {intent.setDataAndType(Uri.fromFile(file), "video/*");intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
startActivity(intent);
二、播放Url视频（GSYVideoPlayer类的使用）
效果：
播放Url视频
1、导入依赖
implementation 'com.github.CarGuo.GSYVideoPlayer:GSYVideoPlayer:v8.1.7-release-jitpack'
2、xml文件
<com.shuyu.gsyvideoplayer.video.StandardGSYVideoPlayerandroid:id="@+id/video_player"android:layout_width="match_parent"android:layout_height="220dp" />
3、Activity中调用
（1） 绑定控件
@InjectView(id = R.id.video_player)
StandardGSYVideoPlayer mVideoPlayer;
（2）播放视频
视频Url例子：https://recordcdn-qk.jfdaily.com/upload/vod/user1694515885005019/1697678251135382/preview/video.mp4
//播放横屏视频boolean setUp = mVideoPlayer.setUp("视频Url", true, "名字");
//设置封面
// if (setUp) {
// Glide.with(this).load(productItem.getCapture()).into((ImageView) mVideoPlayer.getThumbImageView());
// }
//隐藏自带的标题和返回键
mVideoPlayer.getTitleTextView().setVisibility(View.GONE);mVideoPlayer.getBackButton().setVisibility(View.GONE);//全屏按键
mVideoPlayer.getFullscreenButton().setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {mVideoPlayer.startWindowFullscreen(ProductDetailActivity.this,false,true);}
});
GSYVideoType.setShowType(GSYVideoType.SCREEN_TYPE_DEFAULT);
//根据视频尺寸，自动选择竖屏全屏或者横屏全屏
mVideoPlayer.setAutoFullWithSize(true);
//全屏动画
mVideoPlayer.setShowFullAnimation(true);
//开始播放
mVideoPlayer.startPlayLogic();
（3）相关生命周期中添加操作
@Overridepublic void onBackPressed() {if (GSYVideoManager.backFromWindowFull(this)){return;}super.onBackPressed();}@Overrideprotected void onResume() {super.onResume();mVideoPlayer.onVideoResume();}@Overrideprotected void onPause() {super.onPause();mVideoPlayer.onVideoPause();}@Overrideprotected void onDestroy() {super.onDestroy();GSYVideoADManager.releaseAllVideos();}
