是否可以将列表视图的java编码中的文本添加到Android中的选框滚动。如果是的话，请告诉我怎么做？
如果需要，我将发布使用的代码。 这是使用的listview的XML如下
<?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>

如果你需要移动文字，也许这会有所帮助：
http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element
如果你的TextView文本太大并且你想让它移动以便人们可以读取整个内容，请尝试.xml文件中的android:ellipsize="marquee"或Java代码：
textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
答案 1 :(得分：1)
如果android库不够，你可以随时使用java编码。创建一个线程类，用于获取视图并随时更改条件。您可以创建一个调用该类的意图。
答案 2 :(得分：1)
您可以使用 TextSwitcher 并在其上应用动画。
尝试以下代码：
public class TextSwitcherActivity extends Activity implements ViewSwitcher.ViewFactory,
View.OnClickListener
{
private TextSwitcher m_switcher;
private Button m_nextButton;
private int m_counter = 0;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m_switcher = (TextSwitcher) findViewById(R.id.tsSwitcher);
m_switcher.setFactory(this);
Animation in = AnimationUtils.loadAnimation(this, android.R.anim.fade_in);
Animation out = AnimationUtils.loadAnimation(this, android.R.anim.fade_out);
m_switcher.setInAnimation(in);
m_switcher.setOutAnimation(out);
m_nextButton = (Button) findViewById(R.id.next);
m_nextButton.setOnClickListener(this);
updateCounter();
}
/**
* Update counter value
*/
public void onClick(View v)
{
m_counter++;
updateCounter();
}
/**
* Set text on textswitcher
*/
private void updateCounter()
{
m_switcher.setText(String.valueOf(m_counter));
}
public View makeView()
{
TextView t = new TextView(this);
t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
t.setTextSize(36);
return t;
}
您可以定义自己的动画以获得选框效果。

以下是示例
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/mywidget"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:lines="1"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textColor="#ff4500"
android:text="Simple application that shows how to use marquee, with a long text" />
在java中（如果您正在使用Listview并绑定适配器，那么当您对Layout及其视图组件进行充气时，在getview中，将所选标志设置为true到TextView。）
tv = (TextView) this.findViewById(R.id.tv);
tv.setSelected(true);
