通知公告TextSwitcher自动上下滚动带点击事件

    今天项目中用到这样一个小功能，找了好些都不是很合适，参考了很多资料然后根据项目需求终于在下班前不辱使命。马上下班了，就不墨迹了。直接上代码，很简单稍微有点功底的朋友都能看懂

效果图：

 首先是anim下面有两个文件 

push_up_in.xml

xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false"
    android:zAdjustment="top">
    
    <translate
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromYDelta="100%"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="0" />
    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />


set>

还有一个push_up_out.xml

xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false"
    android:zAdjustment="bottom">
    
    <translate
        android:duration="400"
        android:fromYDelta="0"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="-100%" />

    <alpha
        android:duration="400"
        android:fromAlpha="1.0"
        android:toAlpha="0.0" />


set>

然后ManiActivity的布局文件中

<TextSwitcher
    android:id="@+id/tv_message"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inAnimation="@anim/push_up_in"
    android:outAnimation="@anim/push_up_out"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true">

TextSwitcher>

然后下来是 MainActivity了

package text.my.mytextswitcher;

    private String[] news={"双11回馈活动产品利率增长0.05%","国家大数据发展纲要","郑重公告","某某网站会员须知","网站维护公告"};
    private int index = 0;//textview上下滚动下标
    public static final int NEWS_MESSAGE_TEXTVIEW = 100;//通知公告信息



    Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what){
                case NEWS_MESSAGE_TEXTVIEW:
                    index++;
                    textSwitcher.setText(news[index%news.length]);
                    if (index == news.length) {
                        index = 0;
                    }
                    break;
                default:

        }

                        break;
                    default:
                        break;
                }
            }
        });
    }

    private void newsMessage() {
        textSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
            @Override
            public View makeView() {

                textView.setSingleLine();
