Android elipsize TextView 如果将文本视图放在列表视图之后不起作用

Question

我发现非常奇怪的行为与省略textview。它不会滚动文本，比如把textview放在listview之后。如果我把textview在布局的开始它的工作。会是什么呢?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
<!--
    <TextView
            android:text="START | lunch 20.00 | Dinner 60.00 | Travel 60.00 | Doctor 5000.00 | lunch 20.00 | Dinner 60.00 | Travel 60.00 | Doctor 5000.00 | END"
            android:id="@+id/MarqueeText1"
            android:layout_width="fill_parent"
            android:layout_height="40dp"
            android:singleLine="true"
            android:ellipsize="marquee"

我的布局

如果你想要滚动，你的textView的高度必须是wrap_content

如果您在dp中指定，您将无法实现目标

<TextView
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:text="START | lunch 20.00 | Dinner 60.00 | Travel 60.00 | Doctor 5000.00 | lunch 20.00 | Dinner 60.00 | Travel 60.00 | Doctor 5000.00 | END"
            android:id="@+id/MarqueeText1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:singleLine="true"
            android:ellipsize="marquee"
            android:marqueeRepeatLimit="marquee_forever"
            android:scrollHorizontally="true"
            android:paddingLeft="15dip"
            android:paddingRight="15dip"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:freezesText="true"/>
