Answer 1

您只需更改这两个属性的值

即可

    app:expandedTitleMarginEnd="64dp"
    app:expandedTitleMarginStart="48dp"

in

   <android.support.design.widget.CollapsingToolbarLayout
    android:id="@+id/collapsing_toolbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_scrollFlags="scroll|exitUntilCollapsed"
    android:fitsSystemWindows="true"
    app:contentScrim="?attr/colorPrimary"       
    app:expandedTitleMarginStart="48dp"
    app:expandedTitleMarginEnd="64dp"
    app:expandedTitleMarginBottom="60dp">

Answer 2

尝试将 expandedTitleGravity 添加到 CollapsingToolbarLayout 作为应用属性：

app:expandedTitleGravity="center_horizontal"

示例：

<android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:contentScrim="@color/colorPrimary"
        app:expandedTitleGravity="center_horizontal"            
        app:layout_scrollFlags="scroll|exitUntilCollapsed">
