如何在仪表板布局中显示特定图标？-Howtodisplayspecificiconsindashboardlayout?

I am developing an android application in that,I am using dashboard layout that contains icons(showed in image-1).Dashboard layout is common for all the three tabs,Now my dashboard layout is looking below,

我正在开发一个Android应用程序,我正在使用包含图标的仪表板布局(在图像-1中显示)。仪表板布局对于所有三个选项卡都很常见,现在我的仪表板布局如下所示,

Bydefaultly ,when i am login my app the invitation tab will opened as similar to above image.In that image dashboard layout have 3 icons(i.e "dropdown,event,settings") But i want to change icon on dashboard based on tab click functionality.

默认情况下,当我登录我的应用程序时,邀请选项卡将打开,类似于上面的图像。在该图像仪表板布局有3个图标(即“下拉列表,事件,设置”)但我想根据选项卡点击功能更改仪表板上的图标。

for example,

In image-2 ,"Invitation tab" need to show "settings icon" only on dashboard layout except that icon no other icon need to display when i am in "invitation tab".

在图像2中,“邀请选项卡”仅需要在仪表板布局上显示“设置图标”,除了该图标当我在“邀请选项卡”中时不需要显示其他图标。

Similarly in image-3, when i am in "event tab" i need to show "event & settings" icons in dashboardlayout.

同样在图像3中,当我在“事件选项卡”中时,我需要在dashboardlayout中显示“事件和设置”图标。

In image-4, when i am in "groupchat tab" i need to show "dropdown & settings" icons in dashboard layout.

在图像4中,当我在“群聊”选项卡中时,我需要在仪表板布局中显示“下拉列表和设置”图标。
