像微信朋友圈點(diǎn)贊功能如：張三、李四、王五、這種格式

最早做法是在layout中創(chuàng)建一個(gè)父類容器如linearlayout然后在創(chuàng)建一個(gè)子layout，在代碼中 通過for循環(huán)addView添加到父類容器當(dāng)中，雖然可以實(shí)現(xiàn)效果但是這樣無形中會(huì)增加很多view控件。

通過SpannableStringBuilder只通過一個(gè)textview就可以實(shí)現(xiàn)上面的效果。

InvitationLike userLike; SpannableStringBuilder builder = new SpannableStringBuilder();SpannableString spannableString;for(int i=0;i<userLikeList.size();i++){userLike=userLikeList.get(i); String strUserName="、"+userLike.getUsername(); spannableString = new SpannableString(strUserName);spannableString.setSpan(likeTextViewCliceSpan(userLike), 0, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(spannableString);} txtUserName.setText(builder.subSequence(1, builder.length()));txtUserName.setMovementMethod(LinkMovementMethod.getInstance());

likeTextViewCliceSpan是事件方法

private ClickableSpan likeTextViewCliceSpan(final InvitationLike user_like){ClickableSpan clickableSpan=new ClickableSpan() {@Overridepublic void onClick(View widget) {StartPace(user_like.getUtid(),user_like.getUid(),user_like.getUsername());}@Overridepublic void updateDrawState(@NonNull TextPaint ds) {super.updateDrawState(ds);//根據(jù)自己情況設(shè)置相應(yīng)字體顏色ds.setColor(mContext.getResources().getColor(R.color.broadcast_list_name));ds.setUnderlineText(false);ds.clearShadowLayer();} };return clickableSpan;}

同理微信中的回復(fù)功能也一樣實(shí)現(xiàn)通過一個(gè)textview實(shí)現(xiàn)，如果實(shí)用多個(gè)textview就很難保證字體對(duì)齊方式。

李四回復(fù)張三：謝謝

張三：不錯(cuò)啊

這個(gè)樣式父類必須創(chuàng)建一人上layout，因?yàn)橛卸嘈?#xff0c;每行是一個(gè)textview控件,textviewClickSpan也是事件方法和上面基本一樣這里就是粘貼了

private void userCommentList(final int index,LinearLayout linearLike, final List<NewCommentModel> commentList){linearLike.removeAllViews();NewCommentModel commentModel;for(int i=0;i<commentList.size();i++){commentModel=commentList.get(i); View view=LayoutInflater.from(mContext).inflate(R.layout.view_userlike_txtname,new LinearLayout(mContext));final CustomTextView txt_commentContent=(CustomTextView)view.findViewById(R.id.txt_username); ForegroundColorSpan replySpan = new ForegroundColorSpan(mContext.getResources().getColor(R.color.login_font));ForegroundColorSpan contentSpan = new ForegroundColorSpan(mContext.getResources().getColor(R.color.login_font));SpannableStringBuilder builder = new SpannableStringBuilder();SpannableString fromSpannable,spannableReply,toSpannable,contentSpannable;if(TextUtils.isEmpty(commentModel.getTousername())){ fromSpannable = new SpannableString(commentModel.getFromusername()+": ");fromSpannable.setSpan(textviewClickSpan(false,commentModel), 0, fromSpannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(fromSpannable);}else{ fromSpannable = new SpannableString(commentModel.getFromusername());fromSpannable.setSpan(textviewClickSpan(false,commentModel), 0, fromSpannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(fromSpannable);spannableReply=new SpannableString(mContext.getResources().getString(R.string.etxt_reply_hit));spannableReply.setSpan(replySpan, 0, spannableReply.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(spannableReply);toSpannable = new SpannableString(commentModel.getTousername()+": ");toSpannable.setSpan(textviewClickSpan(true,commentModel), 0, toSpannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(toSpannable); }contentSpannable = new SpannableString(commentModel.getContent());contentSpannable.setSpan(contentSpan, 0, contentSpannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);builder.append(contentSpannable);txt_commentContent.setText(builder);txt_commentContent.setMovementMethod(LinkMovementMethod.getInstance());linearLike.addView(view);} }
