我无法以编程方式更改自定义操作栏的标题，也无法将配置文件图像添加到操作栏。我无法理解我的实现错误。以下是我的代码：
actionbar_home
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/tabbackground"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<ImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profileImageActionBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:visibility="visible"
app:border_width="1dp"
app:border_color="#FFFFFF"
android:layout_alignParentLeft="true"
/>
<TextView
android:id="@+id/actionbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:maxLines="1"
android:singleLine="true"
android:text="Home"
android:textColor="@color/white"
android:textSize="22sp"/>
</RelativeLayout>

答案 0 :(得分：2)
在您的情况下，您要对视图进行两次充气。
在这一行：
View mCustomView = mInflater.inflate(R.layout.actionbar_home, null);
这一行：
getSupportActionBar().setCustomView(R.layout.actionbar_home);
因此，当访问“actionbarTitle”时，您引用的是第一次通货膨胀，而不是附加到ActionBar的实际视图（因为方法setCustomView（int id）会使视图本身膨胀，请参阅docs）。
要访问实际的标题，您需要使用：
getSupportActionBar().setCustomView(mCustomView);
或者在将资源设置为ActionBar之后初始化“mCustomView”视图：
getSupportActionBar().setCustomView(R.layout.actionbar_home);
mCustomView = getSupportActionBar().getCustomView();
