I am trying to add a button to title bar but I couldnt succeed. I have read many articles about this but they all explain the way that doesnt fit my situtation. I am using ScrollView to make the screen scrollable. but articles suggest me to use linear layout. How can I make it scrollable and have a button on title bar?

make title.xml and design your title : place buttonetc
制作 title.xml 并设计您的标题：放置按钮等
on activity
在活动中
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);
you will access to elements on title the same way you do on main layout .using findviewbyid
您将像在主布局上一样访问标题上的元素。使用 findviewbyid
for avoiding some look problems
避免一些外观问题
<style name="theme">
<item name="android:windowTitleBackgroundStyle">@style/themeTitleBackground</item>
<item name="android:windowTitleSize">65dip</item>
</style>
<style name="themeTitleBackground">
<item name="android:layout_height">wrap_content</item>
</style>
inside androidmanifest
在androidmanifest里面
<activity android:theme="@style/theme"
