TextView 上下广告翻滚 和 左右滚动

左右滚动相对简单一些...,,系统内置有一些值可以设置

<TextView
android:id="@+id/textview"
android:layout_width="100px"//此处为文本显示区域的宽度此值必须比你的文本宽度要小否则是没有效果的
android:layout_height="wrap_content"
android:text="@string/str"
android:textColor="@drawable/red"
android:layout_x="61px"
android:layout_y="69px"
android:scrollX="2px"
android:singleLine="true"  //设置只有一行
android:scrollHorizontally="true"//水平滚动为true
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
>

而上下翻滚网上模版很多....需要自定义一下了....在这里....我建议使用gethub上开元的项目...原因为什么?因为好用啊,不用引入什么,,,就一个自定义类加进去...想怎么改就怎么改...对字符串的字体修改也简单,因为在loopertextview类里面,你就可以进行修改了

一个LooperTextView类...这个是在github上看到别人写的,地址：https://github.com/LeeYawei/Android-TipView 感谢作者,在这把代码贴下

在xml里面也简单

<com.blzx.view.LooperTextView  //改好你的包名
android:id="@+id/loopertv"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</com.blzx.view.LooperTextView>

使用代码如下

mLooperTextView = (LooperTextView) view.findViewById(R.id.loopertv);
mLooperTextView.setTipList(generateTips());

private List<String> generateTips() {
List<String> tips = new ArrayList<>();
tips.add("恭喜188******24获得:老婆杨幂一枚);
tips.add("恭喜148******86获得:一念成佛");
tips.add("恭喜152******45获得:得到七龙珠");
return tips;
}

搞定....!!一个完美的上下滚动就出现了....附上效果图....喇叭图片自己找...





你问传一个字符串  为什么前后颜色不一样....请你翻看前面的文章...谢谢...可以随心所欲改变你的TextView内的任何东西...
