我正在試圖創建一個與2 TextView的ListView。我在Java中並不擅長，因此我通常會遵循許多教程並將它們結合起來以創建我所需要的內容。列表視圖上的多個TextView
但我一直在努力，兩位導遊沒有多少成功結合在一起...
這裏是我試圖按照添加第二TextView教程： https://www.youtube.com/watch?annotation_id=annotation_3104328239&feature=iv&src_vid=8K-6gdTlGEA&v=E6vE8fqQPTE
但是這並未」因爲我很難理解我如何實現他正在做的事情，所以我真的幫助了我。
到目前爲止，我所瞭解的是，我需要增加我的項目是這樣的：
countryList.add(new EntryItem("Électron","1/6"));
要做到這一點我必須修改EntryItem和我的類，它擴展BaseAdapter
但我並沒有取得成功。
什麼是添加我的第二個TextView的最佳方式？
