我的playvideo活动中有一个videoview和listview / gridview。
videoview中已经播放了一个视频。但是现在我想播放listview / gridview中显示的其他视频，我该怎么做？

最佳答案
打开启动应用程序时，您需要获取数据并将其存储在变量中或数据库中。
创建一个ChannelList类型List（List<ChannelList>）并将ChannelList数据存储到其中。
List<ChannelList> list = new ArrayList<>(); // containing all data
您可以存储
Title，VideoUrl，iconUrl并将其添加到list。单击列表项时，您将使用
setOnItemClickListener获得职位。然后使用该位置获取单击的
ChannelList位置。假设您的列表类型变量为
channelList。listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ChannelList channelList= list.get(position);
// now you have all data of clicked ChannelList
// do whatever you like
//channelList.getVideoUrl(); etc as your getter method
}
}
});
