custom component toolbar fragment with onOptionmenu items

问题

I am stuck simple issue and i know i am doing something minor wrong , My issue is when i am using set Toolbar in MainActivity and after when i am trying to add optionMenu in fragment at a time my toolBar's child component(RelativeLayout in my case) size changed..

Here is my code :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:id="@+id/admin_toolbar"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="@color/button_blue"
        app:contentInsetStart="0dp">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:background="@color/colorPrimaryDark">

            <TextView
                android:id="@+id/admin_toolbar_title"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center_horizontal|center_vertical"
                android:text="@string/zenith"
                android:textColor="@color/white"
                android:visibility="gone" />

            <ImageView
                android:id="@+id/admin_toolbar_icon"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentStart="true"
                android:layout_centerVertical="true"
                android:padding="10dp"
                android:src="@drawable/ic_drawer_icon" />

            <ImageView
                android:id="@+id/adminhome_cust_titleimage"
                android:layout_width="@dimen/_100sdp"
                android:layout_height="match_parent"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:scaleType="fitCenter"
                android:src="@drawable/small_app_logo" />

        </RelativeLayout>


    </android.support.v7.widget.Toolbar>

    <include layout="@layout/content_admin_main" />


</LinearLayout>

Fragment :

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.fragment_admin_home, container, false);
        utils = new Utils(getActivity());
        calendarView = (CompactCalendarView) view.findViewById(R.id.admin_compactcalendar_view);
        setHasOptionsMenu(true);
        toolbar = (Toolbar) getActivity().findViewById(R.id.admin_toolbar);
}
 @Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.adminhome_profilelogo, menu);
}

How can i set my imageView in proper center of toolas you can see in first image..

Try this

        <ImageView
            android:id="@+id/admin_toolbar_icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_centerVertical="true"
            android:padding="10dp"
            android:src="@drawable/ic_drawer_icon" />

        <ImageView
            android:id="@+id/adminhome_cust_titleimage"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_toLeftOf="@+id/admin_toolbar_icon"
            android:layout_alignParentRight="true"
            android:scaleType="fitCenter"
            android:src="@drawable/small_app_logo" />

But anyway if you will add more menu elements your icon will be centered from end of home button and start of menu. Also you can remove setHasOptionsMenu and add one more ImageView in your RelativeLayout and your code will works.

Instead of using option menu you can add an extra ImageView to Toolbar RelativeLayout with aligned right for your profile icon.

Here is an example:

<android.support.v7.widget.Toolbar
    android:id="@+id/admin_toolbar"
    android:layout_width="match_parent"
    android:layout_height="60dp"
    android:background="@color/colorPrimaryDark"
    app:contentInsetStart="0dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimaryDark">


        <ImageView
            android:id="@+id/admin_toolbar_icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_centerVertical="true"
            android:padding="10dp"
            android:src="@drawable/ic_drawer_icon" />

        <ImageView
            android:id="@+id/adminhome_cust_titleimage"
            android:layout_width="100dp"
            android:layout_height="match_parent"
            android:layout_centerHorizontal="true"
            android:scaleType="fitCenter"
            android:src="@mipmap/ic_launcher" />

        <ImageView
            android:id="@+id/profile"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:layout_alignParentRight="true"
            android:layout_centerHorizontal="true"
            android:scaleType="fitCenter"
            android:src="@mipmap/ic_launcher" />

    </RelativeLayout>

</android.support.v7.widget.Toolbar>
