在這裏的問題看起來像它有很好的例子,應該與在答案中描述的一個小修復工作:http://stackoverflow.com/questions/33132908/drawerlayout-collapsingtoolbar-fragments-toolbar-wont-collapse-or -show-ima –

@Daniel Nugent,thx。但這不適合我。也許是因爲我在片段中使用ListView?我只是添加應用程序:layout_collapseMode =「pin」,但不會讓我暫停:( – GPPSoft

建議。嘗試將該選項卡放在此https://github.com/chrisbanes/cheesesquare示例中。 – razzledazzle

ListView不與CoordinatorLayout工作。您必須使用RecyclerView

這是因爲ListView沒有實現對滾動行爲至關重要的接口NestedScrollingChild
