如何從不是父項的另一個活動中調用片段？
[英]How to call a fragment from another activity which is not parent?
問題描述
我有一個不是父項的活動，因此我想在單擊圖像視圖時在該活動中調用一個片段。 因此，我在圖像視圖上添加了onclickListner。 單擊圖像視圖時我會吐司，但是片段沒有被調用。 可能是什么問題？ 誰能幫忙..

android:id="@+id/LinearContainer在您的活動布局中沒有任何android:id="@+id/LinearContainer ，因此FragmentManager無處可放置DetailsFragment 。
