我的RecyclerView在協調器佈局中的一個片段內膨脹時拋出上述錯誤。是否有與父佈局的任何連接？我查看了與此錯誤有關的所有答案，但沒有一個可以解決我的問題。下面是片段+適配器RecyclerView拋出java.lang.IllegalStateException：指定的子項已經有一個父

我用盡了一切辦法，包括parent.removeAllViews（ ）但似乎沒有任何工作。我已經實現了其他RecyclerViews以及幾乎相同的代碼，但他們都工作得很好。任何幫助，將不勝感激。
嘗試改變它...... '視圖V = li.inflate（R.layout.job_item_list，父母，假）;' –
謝謝！現在它工作得很好！ –
m將其作爲答案張貼..接受它plz .. –
