同じアクティビティのリストビューからビデオビューへのビデオリンクの送信

Question

私はビデオビューとリストビュー/グリッドビューを私のplayvideoで持っています。 ビデオビューで既に1つのビデオが再生されています。しかし今、私はlistview/gridviewに表示されている他のビデオを再生したいのですが、どうすればいいですか？

Answer 1

あなたがデータを取得し、変数やデータベースに格納する必要があるアプリを起動開きます。

ChannelListタイプList（List<ChannelList>）を作成し、ChannelListデータをそこに格納します。

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

あなたはTitle、VideoUrl、iconUrlを保存し、listに追加することができます。

リストアイテムをクリックすると、setOnItemClickListenerを使用して位置が取得されます。 そして、その位置をクリックしてChannelListの位置を取得します。

リストタイプ変数がchannelListであるとします。

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 

      } 

     } 
    });
