文本字幕动态 [英] text for marquee dynamically
本文介绍了文本字幕动态的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
是否有可能从列表视图的Java代码中添加文本在Android中，以选取框滚动。如果是的话可以请你让我知道如何？
如果需要，我将张贴使用code。
这是用于列表视图的XML如下：
＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：layout_width =FILL_PARENT
机器人：layout_height =WRAP_CONTENT
机器人：方向=垂直＆GT;
＆LT;的LinearLayout
机器人：ID =@ + ID / linearLayout1
机器人：layout_width =FILL_PARENT
机器人：layout_height =WRAP_CONTENT
机器人：方向=横向＆GT;
＆LT; / LinearLayout中＆GT;
＆LT; ListView控件
机器人：ID =@ + ID / audiolist_listView
机器人：layout_width =FILL_PARENT
机器人：layout_height =0dp
机器人：layout_gravity =底
机器人：layout_weight =1
机器人：背景=@绘制/ backgroundimg
机器人：分=@绘制/梯度
机器人：dividerHeight =1DP
机器人：滚动条=垂直＆GT;
＆LT; /＆的ListView GT;＆LT; / LinearLayout中＆GT;
有关列表视图的Java类如下：

解决方案
如果您需要移动的文字，也许这将有助于：
的http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element
如果您有这是太大的文字一个TextView，你想它走动，以便人们可以阅读整个事情，尝试的android：ellipsize =金字招牌在.xml文件，或在Java code： textView.setEllipsize（TextUtils.TruncateAt.MARQUEE）;
Is it possible to add text from java coding of a list view to marquee scroll in Android. If yes can you please let me know how?
If needed I shall post the code used. This was the XML for listview used is as follows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
<ListView
android:id="@+id/audiolist_listView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_gravity="bottom"
android:layout_weight="1"
android:background="@drawable/backgroundimg"
android:divider="@drawable/gradient"
android:dividerHeight="1dp"
android:scrollbars="vertical" >
</ListView>
</LinearLayout>
The java class for listview is as follows
public class Audiovediolist extends Activity implements OnItemClickListener {

If you need to move text around, maybe this will help:
http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element
If you have a TextView with a text that is too big and you want it to move around so people can read the whole thing, try android:ellipsize="marquee" in the .xml file, or in the Java code:
textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
