[英]Coordinator layout is not working with Linearlayout
我想在向下滾動列表視圖時隱藏工具欄並保留選項卡,但是問題是當我將線性布局放置在協調器布局內時,工具欄沒有隱藏,當我刪除線性布局時它起作用了,但是子視圖改變了它們的位置不想,我試圖將linearlayout移到appbarlayout下面,但是向下滾動時橫幅隱藏,這是主要活動xml:

有什么解決辦法嗎? 先感謝您 ??
對於仍然面臨此問題的每個人,這是解決方案y,您只需要將coordinatorlayout放置在相對布局內並添加android:layout_above =“ @ id / progressBarParent”(如果您沒有pregrassbar,則添加@ id / adView),在這里是完整的activity_main xml文件:
