android textview跑马灯效果

<TextView
        android:id="@+id/tvTip"
        android:paddingLeft="@dimen/dp_10"
        android:paddingRight="@dimen/dp_10"
        android:paddingTop="@dimen/dp_12"
        android:paddingBottom="@dimen/dp_12"
        android:text="物流公告：受疫情影响，2020-08-20起，深圳地区暂时不支持发货"
        android:textSize="@dimen/sp_15"
        android:textColor="@color/red_ffe"
        android:singleLine="true"
        android:scrollHorizontally="true"
        android:ellipsize="marquee"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:marqueeRepeatLimit="marquee_forever"
        android:background="@color/red_ffd"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lineView">

        <requestFocus/>

    </TextView>

设置以下属性：
android:singleLine="true"
android:scrollHorizontally="true"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever
这句很重要

如果界面即存在textview跑马灯效果还存在刷新refresh或edittext要把跑马灯布局给抽取出去

<include
        android:layout_below="@+id/lineView"
        android:id="@+id/pmdLay"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        layout="@layout/include_pmd_view"/>
