我已经创建了一系列有100px的固定宽度的标签。制表包含与下面的一些文本的图像。如果文本太长，我希望它会自动滚动。我只想要一行。我尝试以下，但没有奏效。我使用的是Android 2.3：

I've created a series of tabs that have a fixed width of 100px. A tab contains an image with some text below it. If the text is too long to fit, I want it to automatically scroll. I only want one line. I tried the following but it did not work. I am using Android 2.3:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_marginRight="3dp"
    android:layout_marginTop="3dp"
    android:background="#ff737373"
    android:gravity="center"
    android:minWidth="64dp"
    android:orientation="vertical"
    android:padding="3dp" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:tag="tabImage" >
    </ImageView>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:maxWidth="100px"
        android:tag="tabCaption"
        android:textColor="#ffd9d9d9"
        android:textSize="16sp" />

</LinearLayout>

任何想法，为什么不工作？我碰到的解决方案，从另一个发布有用户表示，它的工作原理。

Any idea why this does not work? I came across the solution from another posting and there the user indicated that it works.
