    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:minHeight="?attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:titleTextColor="@android:color/white"
        android:background="#f26925"

       >
    </android.support.v7.widget.Toolbar>
    <!--<TextView
        android:id="@+id/toolbar_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Mumbai"
        android:textColor="@android:color/white"
        style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
        android:layout_gravity="left"
        />-->
    <!-- Layout for content is here. This can be a RelativeLayout  -->

</LinearLayout>

menu_main.xml

<menu 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"
    tools:context=".MainActivity">
    <item
        android:id="@+id/bookmark"
        android:icon="@drawable/bookmark"
        app:showAsAction="ifRoom"
        android:title="Compose">
    </item>
    <item
        android:id="@+id/search"
        android:icon="@drawable/search"
        app:showAsAction="ifRoom|withText"
        android:title="Profile">
    </item>
    <item
        android:id="@+id/loc"
        android:icon="@drawable/loc"
        app:showAsAction="ifRoom|withText"
        android:title="Profile">
    </item>
    <item
        android:id="@+id/menu"
        android:icon="@drawable/menu"
        app:showAsAction="ifRoom|withText"
        android:title="Profile">
    </item>
</menu>

使用此功能后，我无法在工具栏中显示图标。没有图标出现的原因？

Answer 1

Please add menu inflating code inside your Activity
@Override
public boolean onPrepareOptionsMenu(final Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);

    return super.onCreateOptionsMenu(menu);
}

使用工具栏的自定义视图
