Question

我无法理解为什么我的textview没有被泛化。谢谢你的帮助。
我有这个布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="65dp"

    android:orientation="vertical"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:weightSum="1.0" >

    <RelativeLayout style="@style/ItemFlightRouteLayout" >

        <ImageView
            android:id="@+id/routImageTop"

            android:src="@drawable/icon_arrowup_normal" />

        <TextView
            android:id="@+id/routAiroportFrom"
            style="@style/ItemFlightRouteAirportName"

                style="@style/ItemFlightRouteSeparator"
                android:layout_toLeftOf="@+id/txt_gate" />

    <RelativeLayout style="@style/ItemFlightRouteLayout" >

        <ImageView

            <View

                style="@style/ItemFlightRouteSeparator"
                android:layout_toLeftOf="@+id/txt_time2" />

            <RelativeLayout

                <TextView

                    style="@style/ItemFlightRouteText" />
            </RelativeLayout>

            <View
                android:id="@+id/verticalDivider4"
                style="@style/ItemFlightRouteSeparator"
                android:layout_toLeftOf="@+id/txt_gate2" />

            <RelativeLayout
                android:id="@+id/txt_gate2"

            </RelativeLayout>
        </RelativeLayout>
    </RelativeLayout>

</LinearLayout>

和样式：

<style name="ItemFlightRouteLayout">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:layout_weight">0.5</item>
    <item name="android:weightSum">1.0</item>
</style>

<style name="ItemFlightRouteArrow">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:layout_alignParentLeft">true</item>
    <item name="android:layout_centerInParent">true</item>
    <item name="android:layout_marginLeft">5dp</item>
</style>

<style name="ItemFlightRouteAirportName">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_centerVertical">true</item>

    <item name="android:ellipsize">marquee</item>
    <item name="android:padding">2dp</item>
    <item name="android:singleLine">true</item>
    <item name="android:textColor">@android:color/black</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">14sp</item>
</style>

<style name="ItemFlightRouteDescriptionLayout">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_alignParentRight">true</item>
    <item name="android:layout_gravity">right</item>

Answer 1

最后我知道了！我做了什么：将routImageTop和routAiroportFrom移动到LinearLayout，在父左侧对齐并设置android:layout_toLeftOf="@+id/topDescription"
现在它有效。

Answer 2

添加你的Xml

<item name="android:marqueeRepeatLimit">marquee_forever</item>

在活动中

your_textview.setSelected(true);
your_textview.setSingleLine(true);
your_textview.setEllipsize(TruncateAt.MARQUEE);

我认为你也可以将这些值放在Xml中......

希望这个帮助

Answer 3

TextView需要专注于在TextView中滚动选框。您是否尝试使用selected_state，requestFocus或setSelected将焦点设置为TextView？

Make a Scrolling Marquee, using scrollHorizontally, in a TextView

Deprecated: Make a Scrolling Marquee, using singleLine, in a TextView

TextView ellipsize在RelativeLayout中不起作用
