CircleImageView是圆形图片，网上一搜就有。

public class Barrage implements Serializable {private String barrageInfo;private String barrageUrl;public Barrage(String barrageInfo, String barrageUrl) {this.barrageInfo = barrageInfo;this.barrageUrl = barrageUrl;}public String getBarrageInfo() {return barrageInfo;}public void setBarrageInfo(String barrageInfo) {this.barrageInfo = barrageInfo;}public String getBarrageUrl() {return barrageUrl;}public void setBarrageUrl(String barrageUrl) {this.barrageUrl = barrageUrl;}
}

接下来就是Tm的自定义

public class BarrageView extends FrameLayout {private static ArrayList<Barrage> mData = new ArrayList<>(); //数据private int nowIndex = 0; //mData的下标private Bitmap nowBitmap; //当前图片private int width;                //控件宽private int height;               //控件高private float scale;              //像素密度private FrameLayout frameLayout;private FrameLayout.LayoutParams tvParams;static boolean IS_START = false;    //判断是否开始long allTime; //视频总时长long startTime; //开始时间Handler handler = new Handler() {@Overridepublic void handleMessage(Message msg) {Barrage barrage = (Barrage) msg.getData().getSerializable("barrage");final LinearLayout layout = (LinearLayout) LayoutInflater.from(getContext()).inflate(R.layout.barrage_itme, null);layout.setLayoutParams(tvParams);//随机获得Y值layout.setY(getRandomY());layout.setX(width + layout.getWidth());//设置文字TextView textView = (TextView) layout.findViewById(R.id.barrage_item_tv);textView.setText(barrage.getBarrageInfo());//设置图片CircleImageView imageView = (CircleImageView) layout.findViewById(R.id.barrage_item_img);if (nowBitmap != null) {imageView.setImageBitmap(nowBitmap);}frameLayout.addView(layout);final ObjectAnimator anim = ObjectAnimator.ofFloat(layout, "translationX", -width);anim.setDuration(10000);//释放资源anim.addListener(new Animator.AnimatorListener() {@Overridepublic void onAnimationStart(Animator animation) {}@Overridepublic void onAnimationEnd(Animator animation) {anim.cancel();layout.clearAnimation();frameLayout.removeView(layout);}@Overridepublic void onAnimationCancel(Animator animation) {}@Overridepublic void onAnimationRepeat(Animator animation) {}});anim.start();}};/*** 使用httprulconnection通过发送网络请求path获得bitmap** @param path* @return*/public static Bitmap getBitmapFromUrl(String path) {try {//获得urlURL url = new URL(path);//打开 httpRulConnection 获得实例HttpURLConnection conn = (HttpURLConnection) url.openConnection();//设置超时时间conn.setConnectTimeout(5000);//设置Getconn.setRequestMethod("GET");//连接成功if (conn.getResponseCode() == 200) {//获得输入流InputStream inputStream = conn.getInputStream();//得到bitmapBitmap bitmap = BitmapFactory.decodeStream(inputStream);if (bitmap == null) {}//返回return bitmap;}//错误信息处理} catch (Exception e) { //打印错误信息e.printStackTrace();}return null;}int lastY;//上一次出现的Y值/*** 获得随机的Y轴的值** @return*/private float getRandomY() {int tempY;int rY;int result = 0;// height * 2 / 4 - 25//首先随机选择一条道路int nowY = (int) (Math.random() * 3);switch (nowY) {case 0:nowY = avoidTheSameY(nowY, lastY);//第一条tempY = height / 4 - 25;rY = (int) (Math.random() * height / 4);if (rY >= height / 8) {result = tempY + rY;} else {result = tempY - rY + 50;}lastY = nowY;break;case 1:nowY = avoidTheSameY(nowY, lastY);//第二条tempY = height / 2 - 25;rY = (int) (Math.random() * height / 4);if (rY >= height / 8) {result = tempY + rY;} else {result = tempY - rY;}lastY = nowY;break;case 2:nowY = avoidTheSameY(nowY, lastY);//第三条tempY = height * 3 / 4 - 25;rY = (int) (Math.random() * height / 4);if (rY >= height / 8) {result = tempY + rY - 50;} else {result = tempY - rY;}lastY = nowY;break;}return result;}/*** 避免Y重合的方法** @param lastY* @return*/private int avoidTheSameY(int nowY, int lastY) {if (nowY == lastY) {nowY++;}if (nowY == 4) {nowY = 0;}return nowY;}public BarrageView(Context context, AttributeSet attrs) {super(context, attrs);}@Overrideprotected void onLayout(boolean changed, int left, int top, int right, int bottom) {super.onLayout(changed, left, top, right, bottom);width = getWidth(); //宽度height = getHeight();   //高度init();}private void init() {setTime(600000);    //设置初始时长，改完记得删startTime = System.currentTimeMillis();scale = this.getResources().getDisplayMetrics().density;//获得自身实例frameLayout = (FrameLayout) findViewById(R.id.barrageView);tvParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, 50);if (IS_START) {//开始动画线程startBarrageView();IS_START = false;}}public void startBarrageView() {//开启线程发送弹幕new Thread() {@Overridepublic void run() {while ((System.currentTimeMillis() - startTime < allTime)&& (nowIndex <= mData.size() - 1)) {try {nowBitmap = getBitmapFromUrl(mData.get(nowIndex).getBarrageUrl());Message message = new Message();Bundle bundle = new Bundle();bundle.putSerializable("barrage", mData.get(nowIndex));nowIndex++;message.setData(bundle);handler.sendMessage(message);Thread.sleep((long) (Math.random() * 3000) + 1000);} catch (InterruptedException e) {e.printStackTrace();}}return;}}.start();}@Overrideprotected void onDraw(Canvas canvas) {super.onDraw(canvas);}//设置数据public void setSentenceList(ArrayList<Barrage> data) {mData = data;IS_START = true;}//获得视频总时长public void setTime(long time) {allTime = time;}
}

之后在声明View传入数据就可以了

<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="com.see.tmlayout.MainActivity"><com.see.tmlayout.BarrageViewandroid:id="@+id/barrageView"android:layout_width="match_parent"android:layout_height="400dp"/></RelativeLayout>

public class MainActivity extends AppCompatActivity {private BarrageView mBarrageView;private ArrayList<Barrage> data;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initView();}private void initView() {data = new ArrayList<>();for (int i = 0; i < 50; i++) {data.add(new Barrage("测试弹幕" + i, "http://pic.818today.com/imgsy/image/2016/0215/6359114592207963687677523.jpg"));}mBarrageView = (BarrageView) findViewById(R.id.barrageView);mBarrageView.setSentenceList(data);}
}

解析的数据添加到data集合里就大功告成了！
