我试图在单击FAB（浮动操作按钮）时显示全屏对话框。我想将视图设置为popup_add_shift_log。该应用不断崩溃，并显示各种错误，您可以看到我在代码中做错的任何事情

Answer 1

  

将对话框对象传递给此方法。

public void resizeDialogToFullscreen(Dialog dialog) {
        if (dialog != null && dialog.getWindow() != null) {
            int width = ViewGroup.LayoutParams.MATCH_PARENT;
            int height = ViewGroup.LayoutParams.MATCH_PARENT;
            dialog.getWindow().setLayout(width, height);
        }
    }
