<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"
