欢迎提 issues ☝☝

• 继承自 View,可使用 View 相关属性；
• 可设置：字体大小颜色、滚动动画速度（时间）、停留显示时间、是否单行显示、单行显示是否带有省略号
• 可监听：不同文字的点击事件、滚动动画开始和结束
• 只有一个类文件，若不想依赖方式使用，将ScrollTextView.class 和 scroll_textview_attrs.xml 添加到本地即可

How to

To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {

        compile 'com.github.Dkaishu:ScrollTextView:V1.2.4'
}

Step 3. Use it in your code

   // .xml file:
   
   <com.dkaishu.scrolltextview.ScrollTextView
       xmlns:scroll_text="http://schemas.android.com/apk/res-auto"
       android:id="@+id/stv_example"
       android:layout_width="match_parent"
       android:layout_height="30dp"
       android:layout_gravity="center_vertical"
       android:padding="5dp"
       scroll_text:ellipsis="false"
       scroll_text:singleLine="true"
       scroll_text:textColor="@android:color/black"
       scroll_text:textSize="14sp"
       />
    
    
    
    
    //java file:
    
    ScrollTextView stvExample = (ScrollTextView) findViewById(R.id.stv_example);

    List<String> textList = new ArrayList<>();
    //note : clickListener 、scrollListener can be null ;
    List<ScrollTextView.OnScrollClickListener> clickListeners = new ArrayList<>();
    List<ScrollTextView.OnScrollListener> scrollListeners = new ArrayList<>();

    textList.add("The adolescent girl from Tennessee is standing on the stage of a drama summer camp in upstate New York. It's a beautiful day. But the girl doesn't feel beautiful. She's not the leggy, glamorous Hollywood type.");
    textList.add("一名少女由田纳西州来到纽约北部，她站在戏剧夏令营的舞台上，虽然天气是那么好，她的心情却一点也不好。");


    clickListeners.add(new ScrollTextView.OnScrollClickListener() {
        @Override
        public void onClick() {
            Toast.makeText(MainActivity.this, "this is text one", Toast.LENGTH_SHORT).show();
        }
    });
    
    clickListeners.add(new ScrollTextView.OnScrollClickListener() {
        @Override
        public void onClick() {
            Toast.makeText(MainActivity.this, "this is text two", Toast.LENGTH_SHORT).show();
        }
    });


    scrollListeners.add(new ScrollTextView.OnScrollListener() {
        @Override
        public void onScrollStart(List<ScrollTextView.TextInfo> passedTextInfos) {
            String text = "";
            for (ScrollTextView.TextInfo s : passedTextInfos) {
                text = text + s.getText();
            }
            Log.e(TAG, "" + text);
        }
        @Override
        public void onScrollEnd(List<ScrollTextView.TextInfo> incommingTextInfos) {
            String text = "";
            for (ScrollTextView.TextInfo s : incommingTextInfos) {
                text = text + s.getText();
            }
            Log.e(TAG, "" + text);
        }
    });
    
//        stvExample.setScrollTime(500);//ms
//        stvExample.setSpanTime(3000);//ms
//        stvExample.setTextColor();
//        stvExample.setTextSize();
        
       //Auto start,so you don't need this line,unless restart.
//        stvExample.startTextScroll();

       //you can also setTextContent in this way below.
        
//        stvExample.setTextContent(textList, clickListeners);
//        stvExample.setTextContent(textList);
//        stvExample.setTextContent(textList, null, scrollListeners);

And you may need Override methods in your activity :

   @Override
   protected void onRestart() {
       super.onRestart();
       stvExample.startTextScroll();
   }

   @Override
   protected void onStop() {
       super.onStop();
       stvExample.stopTextScroll();
   }

That's it!
