I want to display a dialog over an activity but still want to interact with background activity to perform something, while the dialog is being displayed. How can this be done?
推薦答案
使用 DialogFragment，它是一個顯示對話窗口的片段，浮動在其活動窗口的頂部.該片段包含一個 Dialog 對象，它會根據片段的狀態適當地顯示該對象.對話框的控制(決定何時顯示、隱藏、關閉它)應該通過這里的 API 來完成，而不是直接調用對話框，所以你的 Activity 仍然處于控制之中.
Use a DialogFragment, which is a fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog, so your Activity remains in control.
