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:
<?XML版本=1.0编码=UTF-8&GT?;< 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> <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> < / LinearLayout中> < 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> < /&的ListView GT;< / LinearLayout中>
有关列表视图的Java类如下:

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:orientation="horizontal" >
</LinearLayout>
<ListView
android:id="@+id/audiolist_listView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_gravity="bottom"

解决方案
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);
