然后是主要实现代码：

CommentsView

public class CommentsView extends LinearLayout {

 private Context mContext;
 private List mDatas;
 private onItemClickListener listener;

 public CommentsView(Context context) {
  this(context, null);
 }

 public CommentsView(Context context, @Nullable AttributeSet attrs) {
  this(context, attrs, 0);
 }

 public CommentsView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  setOrientation(VERTICAL);
  this.mContext = context;
 }

 /**
  * 设置评论列表信息
  *
  * @param list
  */
 public void setList(List list) {
  mDatas = list;
 }

 public void setOnItemClickListener(onItemClickListener listener) {
  this.listener = listener;
 }

 public void notifyDataSetChanged() {
  removeAllViews();
  if (mDatas == null || mDatas.size() <= 0) {
   return;
  }
  LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
  layoutParams.setMargins(0, 10, 0, 10);
  for (int i = 0; i < mDatas.size(); i++) {
   View view = getView(i);
   if (view == null) {
    throw new NullPointerException("listview item layout is null, please check getView()...");
   }
   addView(view, i, layoutParams);
  }
 }

 private View getView(final int position) {
  final CommentsBean item = mDatas.get(position);
  UserBean replyUser = item.getReplyUser();
  boolean hasReply = false; // 是否有回复
  if (replyUser != null) {
   hasReply = true;
  }
  TextView textView = new TextView(mContext);
  textView.setTextSize(15);
  textView.setTextColor(0xff686868);

  SpannableStringBuilder builder = new SpannableStringBuilder();
  UserBean comUser = item.getCommentsUser();
  String name = comUser.getUserName();
  if (hasReply) {
   builder.append(setClickableSpan(name, item.getCommentsUser()));
   builder.append(" 回复 ");
   builder.append(setClickableSpan(replyUser.getUserName(), item.getReplyUser()));

  } else {
   builder.append(setClickableSpan(name, item.getCommentsUser()));
  }
  builder.append(" : ");
  builder.append(setClickableSpanContent(item.getContent(), position));
  textView.setText(builder);
  // 设置点击背景色
  textView.setHighlightColor(getResources().getColor(android.R.color.transparent));

  textView.setMovementMethod(new CircleMovementMethod(0xffcccccc, 0xffcccccc));

  textView.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
    if (listener != null) {
     listener.onItemClick(position, item);
    }
   }
  });

  return textView;
 }

 /**

 /**

  */
 public interface onItemClickListener {

}

CircleMovementMethod

public class CircleMovementMethod extends BaseMovementMethod {
 private final static int DEFAULT_COLOR_ID = android.R.color.transparent;
 /**
  * 整个textView的背景色

  this.clickableSpanBgClor = clickableSpanBgClor;
 }

 public boolean onTouchEvent(TextView widget, Spannable buffer,
        MotionEvent event) {

  int action = event.getAction();
  if (action == MotionEvent.ACTION_DOWN) {
   int x = (int) event.getX();
   int y = (int) event.getY();

   x -= widget.getTotalPaddingLeft();
   y -= widget.getTotalPaddingTop();

   x += widget.getScrollX();
   y += widget.getScrollY();

   Layout layout = widget.getLayout();
   int line = layout.getLineForVertical(y);
   int off = layout.getOffsetForHorizontal(line, x);

   mClickLinks = buffer.getSpans(off, off, ClickableSpan.class);
   if (mClickLinks.length > 0) {
    // 点击的是Span区域，不要把点击事件传递
    Selection.setSelection(buffer,
      buffer.getSpanStart(mClickLinks[0]),
      buffer.getSpanEnd(mClickLinks[0]));
    //设置点击区域的背景色
    mBgSpan = new BackgroundColorSpan(clickableSpanBgClor);
    buffer.setSpan(mBgSpan,
      buffer.getSpanStart(mClickLinks[0]),
      buffer.getSpanEnd(mClickLinks[0]),
      Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
   } else {
    // textview选中效果
//    widget.setBackgroundColor(textViewBgColor);
    widget.setBackgroundResource(DEFAULT_COLOR_ID);
   }

  } else if (action == MotionEvent.ACTION_UP) {
   if (mClickLinks.length > 0) {
    mClickLinks[0].onClick(widget);
    if (mBgSpan != null) {//移除点击时设置的背景span
     buffer.removeSpan(mBgSpan);
    }
   } else {

   }
   Selection.removeSelection(buffer);
   widget.setBackgroundResource(DEFAULT_COLOR_ID);
  } else if (action == MotionEvent.ACTION_MOVE) {
   //这种情况不用做处理
  } else {
   if (mBgSpan != null) {//移除点击时设置的背景span
    buffer.removeSpan(mBgSpan);
   }
   widget.setBackgroundResource(DEFAULT_COLOR_ID);
  }
  return Touch.onTouchEvent(widget, buffer, event);
 }
}

相关数据结构（模拟）

CommentsBean

public class CommentsBean implements Serializable {
 private int commentsId;
 private String content;
 private UserBean replyUser; // 回复人信息
 private UserBean commentsUser; // 评论人信息

 public int getCommentsId() {
  return commentsId;
 }

 public void setCommentsId(int commentsId) {
  this.commentsId = commentsId;
 }

 public String getContent() {
  return content;
 }

 public void setContent(String content) {
  this.content = content;
 }

 public UserBean getReplyUser() {
  return replyUser;
 }

 public void setReplyUser(UserBean replyUser) {
  this.replyUser = replyUser;
 }

 public UserBean getCommentsUser() {
  return commentsUser;
 }

 public void setCommentsUser(UserBean commentsUser) {
  this.commentsUser = commentsUser;
 }
}

UserBean

public class UserBean implements Serializable {
 private int userId;
 private String userName;

 public int getUserId() {
  return userId;
 }

 public void setUserId(int userId) {
  this.userId = userId;
 }

 public String getUserName() {
  return userName;
 }

 public void setUserName(String userName) {
  this.userName = userName;
 }
}

用法



commentView = LvV.find(this, R.id.commentView);
commentView.setList(Data.getComments());
commentView.setOnItemClickListener(new CommentsView.onItemClickListener() {
 @Override
 public void onItemClick(int position, CommentsBean bean) {

 }
});
commentView.notifyDataSetChanged();
