Android的:如何创建一个对话框,一个滚动的标题? [英] Android: How to create a Dialog with a Scrolling title?
问题描述
好了,所以我读过的和开发网站上的自定义对话框的解释 http://developer.android.com/guide/topics/ui/dialogs html的#CustomDialog
Ok so I've read the Custom Dialog explanation on the And Dev website http://developer.android.com/guide/topics/ui/dialogs.html#CustomDialog
这节目的你如何制作一个自定义对话框,而不是如何自定义标题!
It show's you how to make a custom dialog, but not how to customise the title!
基本上我的标题太长,我想它滚动(如TextView的),或者更好的是有一个金字招牌效应,我认为这就是所谓的。
Basically my title is too long and I want it to scroll (like textview) or better still have a 'marquee' effect i think it's called.
或者,如果我不能让它滚动,给它更多的空间来换到更多的线路!
Or if I can't make it scroll, give it more space to wrap onto more lines!
任何想法,我不抱太大的希望,因为它不是在android.dev: - (
Any ideas, I don't hold out much hope as it's not on android.dev :-(
推荐答案
Customizig窗口(从而也对话框)的标题可以通过请求窗口功能CUSTOM_TITLE,必须的setContentView之前完成完成。
Customizig window (and thus also dialog) titles can be done by requesting the window feature CUSTOM_TITLE, which must be done before setContentView.
所以,在对话框/活动的子类的onCreate(),请拨打以下:
So in your Dialog / Activity subclasses onCreate(), call the following:
super.onCreate(savedInstance);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); // <- insert this
然后,在您的setContentView,做到这一点:
Then, after your setContentView, do this:
setContentView(R.layout.main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title); // <- insert this
布局通常可以包含任何你想要的。 对于一个滚动字幕文本控制。例如做到这一点:
The layout can generally contain anything you want. For a marquee text control. e.g. do this:
布局/ custom_title.xml:
layout/custom_title.xml:
<FrameLayout android:id="@+id/FrameLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<TextView android:id="@+id/caption_text"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:text="This is a very very long text that will not fit into a caption regularly, so it will be displayed using marquee..."
android:lines="1"
android:focusable="true"
android:focusableInTouchMode="true"
android:scrollHorizontally="true"
android:marqueeRepeatLimit="marquee_forever"
android:ellipsize="marquee"
></TextView>
</FrameLayout>
由于与字幕功能存在一些制约因素,文本视图必须做出可聚焦和专注的时候它只会滚动(它最初应该是)。
Due to some constraints with the marquee feature, the text view has to be made focusable and it will only be scrolling when focused (which it initially should be).
