Question

我需要设置文本从右到左移动或滚动文本，即如何在android中的CustomActionBar主题上使用选框效果。显示我可以做同样的更改。我一直在附加java和xml以及样式文件。需要帮助

我该如何使用它？

**style.xml**

    <resources xmlns:android="http://schemas.android.com/apk/res/android">

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.



    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.



        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

    <style name="CustomActionBarTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
    </style>

    <!-- ActionBar styles -->
    <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
        <item name="android:background">#F05B30</item>
    </style>

    <style name="fontForNotificationLandingPage">
        <item name="android:fontFamily">NotoSerif-Regular</item>

Answer 1

试试这个

// make the title scroll!
// find the title TextView

TextView title = (TextView) findViewById(android.R.id.title);
// set the ellipsize mode to MARQUEE and make it scroll only once
title.setEllipsize(TruncateAt.MARQUEE);
title.setMarqueeRepeatLimit(1);
// in order to start strolling, it has to be focusable and focused
title.setFocusable(true);
title.setFocusableInTouchMode(true);
title.requestFocus();
