textview 實現跑馬燈文字效果

需要在xml文件中添加幾個屬性。才能實現跑馬燈效果

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:background="#FFFFFF"/>

</LinearLayout>

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView textView = (TextView) this.findViewById(R.id.textView);
        String html = "nihaonihaonihaonihaonihaonihaonihaonihaonihaonihaonihaonihaonihao";
        CharSequence charSequence = Html.fromHtml(html);
        textView.setText(charSequence);
        textView.setMovementMethod(LinkMovementMethod.getInstance());
    }
