Answer 1

Wenn Sie die App, um die Daten zu erhalten, müssen öffnen beginnen und speichern auf einer Variablen oder in die Datenbank.

Erstellen Sie einen ChannelList Typ List (List<ChannelList>) und speichern Sie ChannelList-Daten darin.

List<ChannelList> list = new ArrayList<>(); // containing all data 

können Sie speichern Title, VideoUrl, iconUrl und an den list hinzuzufügen.

Wenn Sie auf ein Listenelement klicken, erhalten Sie die Position mit setOnItemClickListener. Und dann verwenden Sie die Position, um die angeklickte ChannelList Position zu erhalten.

Angenommen, Ihre Listentypvariable ist 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 

      } 

     } 
    });
