我在應用程序中有activity_main.xml。其中包含兩個listview。其中一個負責將json數據視圖作爲帶有自定義列表適配器的列表，另一個用於顯示側面菜單的內容。 通過一個listview我得到json數據，但沒有獲得第二個listview的側面菜單內容，如果我已經在activity_main.xml中聲明。 我不明白它背後的原因是什麼？請幫忙 。活動_main.xml中的兩個ListView。我沒有在同一時間得到同樣的結果
activity_main.xml中

你關閉你的FrameLayout標籤，它是一個容器，且必須包含JSON數據列表視圖。 –
Thanks.I在json數據列表視圖後關閉。但是在點擊側邊菜單列表後，特定的屏幕並未取代json數據列表視圖。 – Neeraj
見附圖。如果我在json的listview之後關閉Framelayout，然後點擊配置文件的側面菜單內容應該替換json數據的列表視圖，但它不會發生。它正在通過json的List視圖。爲什麼？請告訴我 – Neeraj
