仿微信聊天表情发送

如题，这是公司项目的一个功能模块，先上个效果图：



其次大致说说原理：
1，首先判断输入的字符，是否包含表情的文字，比如

这个表情对应的文件名为 emoji_1.png，它对应的文字描述 ： [可爱]，如果我们在输出的是输出这么一句话：老婆，我想你了

。
那么我们对应的根本文字就是：老婆，我想你了[可爱]。

2，具体的转换过程就是用正则表达式比配文字中是否含有[xxx]这类的文字，如果有，那么我们就根据拿到的[xxx]找到它对应的资源文件id,当然这其中有一个关系表，看你怎么处理这个关系了。最后将其用SpannableString替换成文字，表面上显示有图片，其实TextView里的text依然是:老婆，我想你了[可爱]。这个过程明白么？

下面贴上DEMO工程的结构：




再贴上几个重要的类：

接下来是聊天数据填充器的

import android.view.View;
import android.view.ViewGroup;

import android.widget.BaseAdapter;

/**

******************************************
*/
public class ChatMsgAdapter extends BaseAdapter {

public static interface IMsgViewType {
int IMVT_COM_MSG = 0;
int IMVT_TO_MSG = 1;
}

private List<ChatMsgEntity> coll;
private LayoutInflater mInflater;
private Context context;
public ChatMsgAdapter(Context context, List<ChatMsgEntity> coll) {
this.coll = coll;
mInflater = LayoutInflater.from(context);
this.context = context;
}

public int getCount() {
return coll.size();
}

public Object getItem(int position) {
return coll.get(position);
}

public long getItemId(int position) {
return position;
}

public int getItemViewType(int position) {
ChatMsgEntity entity = coll.get(position);

if (entity.getMsgType()) {
return IMsgViewType.IMVT_COM_MSG;
} else {
return IMsgViewType.IMVT_TO_MSG;
}

}

public int getViewTypeCount() {
return 2;
}

public View getView(int position, View convertView, ViewGroup parent) {

ChatMsgEntity entity = coll.get(position);
boolean isComMsg = entity.getMsgType();

ViewHolder viewHolder = null;
if (convertView == null) {
if (isComMsg) {
convertView = mInflater.inflate(
R.layout.chatting_item_msg_text_left, null);
} else {
convertView = mInflater.inflate(
R.layout.chatting_item_msg_text_right, null);
}

viewHolder = new ViewHolder();
viewHolder.tvSendTime = (TextView) convertView
.findViewById(R.id.tv_sendtime);
viewHolder.tvContent = (TextView) convertView
.findViewById(R.id.tv_chatcontent);
viewHolder.isComMsg = isComMsg;

convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}

viewHolder.tvSendTime.setText(entity.getDate());
SpannableString spannableString = FaceConversionUtil.getInstace().getExpressionString(context, entity.getText());
viewHolder.tvContent.setText(spannableString);

return convertView;
}

class ViewHolder {
public TextView tvSendTime;
public TextView tvContent;
public boolean isComMsg = true;
}

}

最开始要读取的表情配置文件

[java]
view plaincopyprint?

package com.example.facedemo;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

import android.content.Context;

/**
*
******************************************
* @author 廖乃波

* @创建时间 : 2013-1-27 下午02:35:09
* @文件描述 : 文件工具类
******************************************
*/
public class FileUtils {
/**
* 读取表情配置文件
*
* @param context
* @return
*/
public static List<String> getEmojiFile(Context context) {
try {
List<String> list = new ArrayList<String>();
InputStream in = context.getResources().getAssets().open("emoji");
BufferedReader br = new BufferedReader(new InputStreamReader(in,
"UTF-8"));
String str = null;
while ((str = br.readLine()) != null) {
list.add(str);
}

return list;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}

下边这个是表情翻页的数据填充，用的是viewpager，每一页填充的是一个gridview

[java]
view plaincopyprint?

package com.example.facedemo;

import java.util.List;

import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
/**

******************************************
*/
public class ViewPagerAdapter extends PagerAdapter {

private List<View> pageViews;

public ViewPagerAdapter(List<View> pageViews) {
super();
this.pageViews=pageViews;
}

// 显示数目
@Override
public int getCount() {
return pageViews.size();
}

@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}

@Override
public int getItemPosition(Object object) {
return super.getItemPosition(object);
}

@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager)arg0).removeView(pageViews.get(arg1));
}

/***
* 获取每一个item�?类于listview中的getview
*/
@Override
public Object instantiateItem(View arg0, int arg1) {
((ViewPager)arg0).addView(pageViews.get(arg1));
return pageViews.get(arg1);
}
}
