如果在listview之后放置textview，android elipsized textview不起作用

Question

我发现椭圆形文本视图的行为非常奇怪。例如，如果将 textview 放在 listview 之后，它不会滚动文本。如果我将 textview 放在布局的开头，它就可以工作。会是什么？

<?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"
            android:marqueeRepeatLimit="marquee_forever"
            android:scrollHorizontally="true"
            android:paddingLeft="15dip"
            android:paddingRight="15dip"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:freezesText="true"/>

    <include layout="@layout/reminder_header_item"/>

    <ListView

            >
    </ListView>

    <View
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"

    <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="40dp"
            android:singleLine="true"
            android:ellipsize="marquee"
            android:marqueeRepeatLimit="marquee_forever"
            android:scrollHorizontally="true"

            android:freezesText="true"/>
    <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:layout_marginBottom="1dp"
            android:layout_alignParentBottom="true"
            android:background="#DADADC" />

</LinearLayout>

我的布局

Answer 1

你想要滚动，你的 textView 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"/>
