我就不bb了，直接上代码了

云端给我传的是一个json数组嘛，我只要取其中某个指定字符，取完后，加到一个string里面，中间用空格隔开，就可以了，很多开源的，满足不了朴实的要求，没办法～

package cn.titansys.fowlet.ui.textview;

import android.app.Activity;
import android.content.Context;
import android.text.Html;
import android.text.TextPaint;
import android.text.TextUtils;
import android.text.method.LinkMovementMethod;
import android.util.Log;
import android.view.View;
import android.view.WindowManager;
import android.widget.TextView;

import com.alibaba.fastjson.JSON;

import java.util.ArrayList;
import java.util.List;

import cn.titansys.fowlet.data.json.DeviceParse;
import cn.titansys.fowlet.model.iSubtitles;
import cn.titansys.fowlet.ui.marquee.CustomerMarqueeView;

public class TextRoll {

    private TextView textView;
    private Activity activity;
    private DeviceParse deviceParse;
    private List<String> stringList = new ArrayList<String>();
    public TextRoll(TextView textView, Activity activity){
        this.textView =textView;
        this.activity =activity;
        deviceParse  = new DeviceParse(activity);
    }

    public void Show(String html){
        CharSequence charSequence = Html.fromHtml(html);
        textView.setText(charSequence);
        textView.setMovementMethod(LinkMovementMethod.getInstance());//添加链接
        textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);//最多几行
        textView.setSingleLine(true);
        textView.setSelected(true);
        textView.setFocusable(false);
        textView.setFocusableInTouchMode(false);

    }

    public void goDo(){

        //Log.e("stringList","smv+"+deviceParse.get_data_app_extra_subtitles());
        if(deviceParse.get_data_app_extra_subtitles()==null){
            textView.setVisibility(View.GONE);
            Log.e("stringList","smv+null");
            return;
        }

        textView.setVisibility(View.VISIBLE);
        List<iSubtitles> subc = JSON.parseArray(deviceParse.get_data_app_extra_subtitles(), iSubtitles.class);
        for (iSubtitles pp : subc) {
//            pp.getContent()
//            pp.getName()
//            pp.isEnable()
            if(pp.isEnable()){
                stringList.add(pp.getContent());
                Log.e("stringList","smv"+stringList.size()+"str"+pp.getContent());
            }
        }
        if(stringList.size()==0){
            textView.setVisibility(View.GONE);
        }else {
            String str = "";
            for (int i = 0; i < stringList.size(); i++) {
                //System.out.println(stringList.get(i));
                str = str + "\t\t\t\t\t\t\t\t\t\t\t\t\t" + stringList.get(i);
            }
            Show(str);
        }


    }

}

使用

    public void barrage(TextView tv_hint) {
        TextRoll textRoll = new TextRoll(tv_hint, activity);
        textRoll.goDo();
    }

布局

    <TextView
        android:visibility="gone"
        android:id="@+id/tv_hint"
        android:textColor="@color/color_white"
        android:textSize="30dp"
        android:textStyle="bold"
        android:gravity="center_vertical"
        android:background="#283747"
        android:marqueeRepeatLimit="marquee_forever"
        android:layout_width="match_parent"
        android:layout_height="40dp"/>
