还是老流程，先来看一下效果图：

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.setHighlightColor(0xff000000);  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; } /**  * 设置评论内容点击事件  *  * @param item  * @param position  * @return  */ public SpannableString setClickableSpanContent(final String item, final int position) {  final SpannableString string = new SpannableString(item);  ClickableSpan span = new ClickableSpan() {   @Override   public void onClick(View widget) {    // TODO: 2017/9/3 评论内容点击事件    Toast.makeText(mContext, "position: " + position + " , content: " + item, Toast.LENGTH_SHORT).show();   }   @Override   public void updateDrawState(TextPaint ds) {    super.updateDrawState(ds);    // 设置显示的内容文本颜色    ds.setColor(0xff686868);    ds.setUnderlineText(false);   }  };  string.setSpan(span, 0, string.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  return string; } /**  * 设置评论用户名字点击事件  *  * @param item  * @param bean  * @return  */ public SpannableString setClickableSpan(final String item, final UserBean bean) {  final SpannableString string = new SpannableString(item);  ClickableSpan span = new ClickableSpan() {   @Override   public void onClick(View widget) {    // TODO: 2017/9/3 评论用户名字点击事件    Toast.makeText(mContext, bean.getUserName(), Toast.LENGTH_SHORT).show();   }   @Override   public void updateDrawState(TextPaint ds) {    super.updateDrawState(ds);    // 设置显示的用户名文本颜色    ds.setColor(0xff387dcc);    ds.setUnderlineText(false);   }  };  string.setSpan(span, 0, string.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  return string; } /**  * 定义一个用于回调的接口  */ public interface onItemClickListener {  void onItemClick(int position, CommentsBean bean); }}

CircleMovementMethod

public class CircleMovementMethod extends BaseMovementMethod { private final static int DEFAULT_COLOR_ID = android.R.color.transparent; /**  * 整个textView的背景色  */ private int textViewBgColor; /**  * 点击部分文字时部分文字的背景色  */ private int clickableSpanBgClor; private BackgroundColorSpan mBgSpan; private ClickableSpan[] mClickLinks; /**  * @param clickableSpanBgClor 点击选中部分时的背景色  */ public CircleMovementMethod(int clickableSpanBgClor) {  this.clickableSpanBgClor = clickableSpanBgClor; } /**  * @param clickableSpanBgClor 点击选中部分时的背景色  * @param textViewBgColor  整个textView点击时的背景色  */ public CircleMovementMethod(int clickableSpanBgClor, int textViewBgColor) {  this.textViewBgColor = textViewBgColor;  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();
