我的HomeActivity包含滑动菜单，其中滑动菜单中的每个选项都会打开一个具有不同标题的新片段。我希望片段和活动的动作栏中的标题出现在center.I尝试使用自定义布局片段 -
final ActionBar ab = getActivity().getActionBar();
ab.setHomeButtonEnabled(true);
ab.setDisplayHomeAsUpEnabled(true);
ab.setDisplayShowTitleEnabled(false);
// actionBar.setDisplayShowHomeEnabled(false);
ab.setCustomView(R.layout.action_bar);
ab.setDisplayShowCustomEnabled(true);
actionbar.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:fontFamily="sans-serif"
android:maxLines="1"
android:text="title"
android:textSize="20sp"
android:gravity="center"/>
</RelativeLayout>
这使标题在中心对齐，但滑动菜单消失。我希望我的所有片段在操作栏的中心显示标题，滑动菜单不应该消失。这是我的清单，styles.xml，活动的代码之一Home Activity的片段和xml文件..

答案 0 :(得分：0)
尝试将以下内容添加到自定义TextView布局的ActionBar中，以使文字居中。
android:layout_gravity="center"
另外，要解释一下，当您设置gravity="center"时，只需将文本置于TextView布局的中心位置。
接下来，您的图标会隐藏，因为您的自定义布局与导航抽屉的图标（侧线菜单）重叠。要解决此问题，最简单的方法是为整个布局设置边距（在您的情况下，自定义操作栏布局的相对布局）。我认为30dp足以涵盖所有屏幕尺寸。
android:layout_marginRight="30dp"
