android - 动态选取框文本

Question

是否可以将来自 ListView 的 java 编码的文本添加到 Android 中的选取框滚动。如果是，请告诉我怎么做？

如果需要，我将发布使用的代码。这是用于 ListView 的 XML，如下所示

<?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>

listview的java类如下

public class Audiovediolist extends Activity implements OnItemClickListener {
    private ListView audioList;

如果您需要移动文本，也许这会有所帮助:

http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element

如果您的 TextView 的文本太大并且您希望它四处移动以便人们可以阅读整个内容，请在 .xml 文件中尝试 android:ellipsize="marquee" ，或者在 Java 代码中:textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
