    <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
    \color{red}{ <requestFocus/>}这句很重要

    \color{red}{注意注意注意注意注意注意注意注意注意注意注意注意!!!!!}
    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"/>
    
    <?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        xmlns:app="http://schemas.android.com/apk/res-auto">
    
        <TextView
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            android:id="@+id/tvTip"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/lineView"
            android:background="@color/red_ffd"
            android:singleLine="true"
            android:scrollHorizontally="true"
            android:ellipsize="marquee"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:marqueeRepeatLimit="marquee_forever"
            android:paddingLeft="@dimen/dp_10"
            android:paddingTop="@dimen/dp_12"
            android:paddingRight="@dimen/dp_10"
            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:textColor="@color/red_ffe"
            android:textSize="@dimen/sp_15">
    
            <requestFocus/>
    
        </TextView>
    
    </androidx.constraintlayout.widget.ConstraintLayout>
