我有一個鏈接在一起的3個不同部分的列表視圖，圖像，文本框和另一個圖像。現在，當我點擊列表視圖時，它會轉到另一個頁面。如果用戶點擊圖片，我希望它將其引導到另一個頁面。請幫忙！！以下是課程代碼。如何將listview中的項目分開以指向不同的頁面？

那麼，有沒有辦法爲用戶點擊，這將引導到另一個頁面列表視圖的某一部分？任何幫助表示讚賞！以下是相關的xml文件。

您可以將onclicklistener設置爲單獨的視圖 –
但是所有都在列表視圖中。我設置了一個listview onclick監聽器。我如何設置onclicklistener分開？ – user3197009
爲你的列表視圖創建自定義適配器，你可以將操作添加到單獨的視圖。 – keshav
