如何在仪表板布局中显示特定的图标？

我正在开发在Android应用程序中，我使用的是包含图标仪表盘布局.Dashboard布局是所有三个标签通用（在图像显示1），现在我的仪表盘布局正在下面，如何在仪表板布局中显示特定的图标？

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

例如，

在图像2中，“邀请标签”需要显示“设置图标”仅除了图标没有其他图标需要显示当我在“邀请标签”仪表盘布局。

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

在图像-4，当我在 “群聊标签” 我需要显示 “下拉菜单&设置” 图标，在仪表盘布局。

我menu_dashboard代码如下

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:appmunu="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    tools:context="ringee.app.com.ringeeapp.UserDashBoard"> 

    <item 
     android:id="@+id/dropdown" 
     android:icon="@drawable/dropdown_icon" 
     android:title="Dropdown" 
     appmunu:showAsAction="always"> 
     <menu> 
      <item 
       android:id="@+id/all" 
       android:title="All" /> 
      <item 
       android:id="@+id/event" 
       android:title="Event" /> 
      <item 
       android:id="@+id/invitation" 
       android:title="Invitation" /> 
     </menu> 
    </item>

我的仪表盘编码是下面，

<?xml version="1.0" encoding="utf-8"?> 
    <android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@android:id/tabhost" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" > 

     <LinearLayout 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:orientation="vertical" > 

      <FrameLayout 
       android:id="@android:id/tabcontent" 
       android:layout_width="fill_parent" 
       android:layout_height="fill_parent" 
       android:layout_weight="1" /> 

      <TabWidget 
       android:id="@android:id/tabs" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:layout_marginBottom="-4dp" 
       android:layout_weight="0" /> 
     </LinearLayout> 

    </android.support.v4.app.FragmentTabHost>

使用工具栏随着活动的图标，当标签更改自定义您的布局

<android.support.v7.widget.Toolbar 
android:id="@+id/toolbar" 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:background="@color/primary" 
android:drawingCacheQuality="low" 
android:minHeight="@dimen/abc_action_bar_default_height_material" 
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" 
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:layout_width="wrap_content" 
       android:layout_height="match_parent" 
       android:layout_gravity="right" 
       android:layout_weight="1" 
       android:background="@android:color/transparent" 
       android:gravity="right"> 

    <ImageView 
     android:id="@+id/notification" 
     android:layout_width="@dimen/abc_action_button_min_width_material" 
     android:layout_height="@dimen/abc_action_bar_default_height_material" 
     android:layout_centerVertical="true" 
     android:gravity="center" 
     android:lines="1" 
     android:padding="5dp" 
     android:src="@drawable/ic_action_notification" 
     android:textAppearance="?android:attr/textAppearanceMedium" 
     /> 

    <ImageView 
     android:id="@+id/searchView" 
     android:layout_width="@dimen/abc_action_button_min_width_material" 
     android:layout_height="@dimen/abc_action_bar_default_height_material" 
     android:layout_centerVertical="true" 
     android:gravity="center" 
     android:lines="1" 
     android:padding="5dp" 
     android:src="@drawable/ic_title_search_default" 
     android:textAppearance="?android:attr/textAppearanceMedium" 
     /> 
</LinearLayout>

和你的活动是这样的

myTabHost.setOnTabChangedListener(new OnTabChangeListener() { 
     @Override 
     public void onTabChanged(String tabId) { 
      if (TAB_1_TAG.equals(tabId)) { 
       notification.setVisibility(View.GONE); 
       searchView.setVisibility(View.VISIBLE); 

      } 
      if (TAB_2_TAG.equals(tabId)) { 
       notification.setVisibility(View.VISIBLE); 
       searchView.setVisibility(View.GONE); 
      } 
     } 
    });
