Question

我有两个问题：在我的应用程序中，我有一个appbar活动和一个回收者视图。当我单击浮动操作菜单的选项时，它会显示全屏对话碎片，但由于某种原因，对话框显示不正确（不是完全全屏）。

结果如下 dialogfragment 此外，当我单击对话框的关闭按钮时，它不仅会关闭对话框，还会关闭活动，并转到上一个活动。我该怎么办。我开始使用Android。我也想为cardview建立一个保证金（左和右）

这是我的代码

Answer 1

首先，您的对话框布局具有顶部填充，以便它没有完整高度。

dialog_contract.xml

 <android.support.design.widget.CoordinatorLayout
 ...
 android:paddingTop="24dp"
 >

其次尝试关注java naming convention，因为您的代码难以阅读

当我单击对话框的关闭按钮时，它不仅会关闭对话框，还会关闭活动，并转到上一个活动。

我最好的猜测是你没有正确处理菜单点击，尝试调用

setHasOptionsMenu(true);

来自dialogFragmen onCreate

的

全屏对话框片段无法正确显示
