前言
这段时间做的东西比较杂，但是对学习来说还是很有帮助的，这次做的基于socket的即时通讯也是为了更加了解IM，本来是打算使用openfire或者apollo服务器来实现的，但是中途时间上的问题，临时改了需求，后期的语音通话还是要借助第三方服务器的，这里主要是自己用myeclipse写了一个简单的代理服务器，主要是将客户端发来的消息转发到已经保存到链表中的socket中，实现比较简单，主要是解决发送图片的模块，我参考了很多文章，但是大多写的都不是很全，故自己写了一下，[socket即时通讯源码](https://github.com/firesmog/MyGreenDao)，写这篇博客，一是为了记录自己的学习进度，而是希望能给正在学习路上的各位同学一点点帮助。
服务端介绍
这里的服务端是采用myeclipse写的，比较简单单，主要负责将任意客户端传过来的消息的进行转发，然后使得客户端收到信息后能在自己的界面上进行展示，具体代码如下，仅供参考。
public class tcpservice { private static final int SERVERPORT = 8090; private static List<Socket> mClientList = new ArrayList<Socket>(); private ExecutorService mExecutorService; private ServerSocket mServerSocket; public static void main(String[] args) { new tcpservice(); } public tcpservice() { try { //服务端套接字，这里给定客户端要连接的目标端口即可 mServerSocket = new ServerSocket(SERVERPORT); //使用线程池，来一个客户端，开一个线程处理 mExecutorService = Executors.newCachedThreadPool(); System.out.println("start..."); Socket client = null; while (true) { //监听客户端的连接，一旦客户端连接上，则将客户端套接字赋值给client client = mServerSocket.accept(); //在链表中保存客户端，以便后面的消息转发 mClientList.add(client); System.out.println(client.toString()); //开启线程 mExecutorService.execute(new ThreadServer(client)); } } catch (IOException e) { e.printStackTrace(); } } //新建自己的线程类，实现线程内run方法的实现 static class ThreadServer implements Runnable { private Socket mSocket; private BufferedReader mBufferedReader; private PrintWriter mPrintWriter; private String mStrMSG; //构造方法，将客户端套接字socket传进来 public ThreadServer(Socket socket) throws IOException { this.mSocket = socket; //获得客户端输入流，用于读取客户端数据 mBufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream())); mStrMSG = "user:"+this.mSocket.getInetAddress()+" come total:" + mClientList.size(); } //run方法的实现 public void run() { try { //判断客户端发送过来的信息是否是要退出聊天 while ((mStrMSG = mBufferedReader.readLine()) != null) { if (mStrMSG.trim().equals("exit")) { mClientList.remove(mSocket); mBufferedReader.close(); mPrintWriter.close(); mStrMSG = "user:"+this.mSocket.getInetAddress()+" exit total:" + mClientList.size(); mSocket.close(); sendMessage(); break; } else { // mStrMSG = mSocket.getInetAddress() + ":" + mStrMSG; System.out.println( mStrMSG); sendMessage(); } } } catch (IOException e) { e.printStackTrace(); } } private void sendMessage() throws IOException { System.out.println(mStrMSG); //遍历所有的客户端套接字，将消息转发出去 for (Socket client : mClientList) { mPrintWriter = new PrintWriter(client.getOutputStream(), true); mPrintWriter.println(mStrMSG); mPrintWriter.flush(); } } }}服务端就介绍到，这里，因为实现比较简单，所以也不多做赘述。
客户端介绍
这里的客户端实在Androidstudio上实现的，逻辑不难，主要是界面上的操作，大家可以参考一下。这里先贴出界面图，比较丑陋，大家见谅。
主界面主要采用的ViewPger+Recycleview，发送表情主要是采用Recycleview+girdView+EditText，，下面写给出主界面布局，以及聊天界面布局，大家仅参考，具体内容，数据资源都在源码中，大家自行下载。
//主界面<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="example.com.myapplication.MainActivity"> <example.com.myapplication.MyViewPager.MyViewPager android:id="@+id/vp_main" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" > android:persistentDrawingCache="animation" </example.com.myapplication.MyViewPager.MyViewPager> <RadioGroup android:id="@+id/rd_group" android:layout_width="match_parent" android:layout_height="90dp" android:layout_alignParentBottom="true" android:orientation="horizontal"> <RadioButton android:id="@+id/rd_1" style="@style/tab_menu_item" android:drawableTop="@drawable/message" android:text="消息"/> <RadioButton android:id="@+id/rd_2" style="@style/tab_menu_item" android:drawableTop="@drawable/contactor" android:text="联系人"/> <RadioButton android:id="@+id/rd_3" style="@style/tab_menu_item" android:drawableTop="@drawable/statues" android:text="动态"/> </RadioGroup></LinearLayout>//聊天界面<LinearLayout xmlns: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=".MainActivity" android:orientation="vertical" > <android.support.v7.widget.RecyclerView android:id="@+id/msg_recyclerView" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"> </android.support.v7.widget.RecyclerView> <LinearLayout android:layout_width="match_parent" android:layout_height="60dp" android:orientation="horizontal" > <ImageView android:id="@+id/iv_motion" android:onClick="true" android:layout_marginLeft="10dp" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="@drawable/chat_icon"/> <EditText android:onClick="true" android:id="@+id/input_text" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:hint="Type something here" android:maxLines="2"/> <Button android:layout_marginLeft="20dp" android:id="@+id/btnsend" android:layout_width="80dp" android:layout_height="50dp" android:layout_marginTop="10dp" android:text="发送" android:textSize="20dp"/> </LinearLayout> <android.support.v4.view.ViewPager android:paddingTop="5dp" android:id="@+id/vp_motion" android:layout_width="match_parent" android:layout_height="150dp" android:visibility="gone"> </android.support.v4.view.ViewPager></LinearLayout>聊天界面当中的girdview是为了展示图片内容的，在初始的时候采用Gone将其隐藏起来，点击的时候将其设置为Visable展示出来，这里要注意的是图片的显示与软键盘弹出来的冲突，具体完全解决问题的做法，本人还没做好，在本demo中只是做了点强制的切换，隐藏，使得在软键盘和图片展示界面切换的时候有点卡顿，大家感兴趣的自己解决一下，解决好了的可以教一下我，谢谢。这里顺便说一下，主界面中使用了MyViewPger是自定义的viewpager主要目的，其实是我自己之前做仿qq的Recycleview的侧滑删除Item操作时，测试事件分发机制用的，感兴趣的同学可以自行添加事件分发方法，打log查看一下事件分发顺序。这里已经有点偏离话题，大家勿怪。
MyViewPger代码如下：package example.com.myapplication.MyViewPager;
import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
/**
* Created by firesmog on 2017/2/22.
*/
public class MyViewPager extends ViewPager {
private boolean noScroll = false;
public MyViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public MyViewPager(Context context) {
super(context);
}
public void setNoScroll(boolean noScroll) {
this.noScroll = noScroll;
}
@Override
public void scrollTo(int x, int y) {
super.scrollTo(x, y);
}
//下面内容其实是为了测试事假分发，其实有点绕，一段时间不做，就会有点生疏
@Override
public boolean onTouchEvent(MotionEvent arg0) {
/* return false;//super.onTouchEvent(arg0); */
Log.i(MyViewPager.class.getSimpleName(), ” onTouchEvent” + ” event = ” + arg0);
if (noScroll){
return false;
}
else
return true;
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev){
Log.i(MyViewPager.class.getSimpleName(), ” dispatchTouchEvent” + ” event = ” + ev + ” noScroll = ” + noScroll);
return super.dispatchTouchEvent(ev);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent arg0) {
Log.i(MyViewPager.class.getSimpleName(), ” onInterceptTouchEvent” + ” event = ” + arg0);
if (noScroll) {
return false;
}
else
return super.onInterceptTouchEvent(arg0);
}
@Override
public void setCurrentItem(int item, boolean smoothScroll) {
super.setCurrentItem(item, smoothScroll);
}
@Override
public void setCurrentItem(int item) {
super.setCurrentItem(item);
}
}
到了这里的话，就需要给girdview，Recycleview等添加适配器了，这两个适配器在写的时候注意的地方有很多，我也是参考了别人的代码，做了修改，时间有点久，不记得是谁的博客了，见谅。首先需要展示图片，所以列出girdview的adapter。代码如下所示。
package example.com.myapplication.Adapter;import android.content.Context;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;import java.util.List;import example.com.myapplication.Bean.HeaderViewBean;import example.com.myapplication.R;/** * Created by firesmog on 2017/3/3. */public class GridViewAdapter extends BaseAdapter { private List<HeaderViewBean> mDatas; private LayoutInflater mLayoutInflater; private Context context; private int columnWidth; /** * 页数下标,从0开始 */ private int mIndex; /** * 每页显示最大条目个数 ,默认是dimes.xml里 HomePageHeaderColumn 属性值的两倍 */ private int mPageSize; /** * @param context 上下文 * @param mDatas 传递的数据 * @param columnWidth * @param mIndex 页码 */ public GridViewAdapter(Context context, List<HeaderViewBean> mDatas, int columnWidth, int mIndex) { this.context = context; this.mDatas = mDatas; mLayoutInflater = LayoutInflater.from(context); this.mIndex = mIndex; mPageSize =28; this.columnWidth= columnWidth; } public GridViewAdapter(Context context, List<HeaderViewBean> mDatas, int index) { this.context = context; this.mDatas = mDatas; mLayoutInflater = LayoutInflater.from(context); this.mIndex = index; mPageSize =28; } /** * 先判断数据集的大小是否足够显示满本页？mDatas.size() > (mIndex+1)*mPageSize, * 如果够，则直接返回每一页显示的最大条目个数mPageSize, * 如果不够，则有几项返回几,(mDatas.size() - mIndex * mPageSize); */ @Override public int getCount() { return mDatas.size() > (mIndex + 1) * mPageSize ? mPageSize : (mDatas.size() - mIndex * mPageSize); } @Override public Object getItem(int position) { return mDatas.get(position + mIndex * mPageSize); } @Override public long getItemId(int position) { return position + mIndex * mPageSize; } @Override public View getView(final int position, View convertView, ViewGroup parent) { Log.i("TAG", "position:" + position); ViewHolder vh = null; if (convertView == null) { convertView = mLayoutInflater.inflate(R.layout.item_gird, parent, false); vh = new ViewHolder(); vh.iv = (ImageView) convertView.findViewById(R.id.id_iv_icon); convertView.setTag(vh); } else { vh = (ViewHolder) convertView.getTag(); } /** * 在给View绑定显示的数据时，计算正确的position = position + mIndex * mPageSize， */ int pos = position + mIndex * mPageSize; vh.iv.setImageResource(mDatas.get(pos).iconRes); return convertView; } class ViewHolder { public TextView tv; public ImageView iv; }}有了展示图片的adapter的界面后，主要就是聊天对话框的dapter，代码如下：
package example.com.myapplication.Adapter;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.LinearLayout;import android.widget.TextView;import java.util.List;import example.com.myapplication.Bean.Msg;import example.com.myapplication.R;/** * Created by firesmog on 2017/3/3. */public class MsgAdapter extends RecyclerView.Adapter<MsgAdapter.ViewHolder>{ List<Msg> msgList; @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recycly, parent, false); return new ViewHolder(view); } @Override public void onBindViewHolder(ViewHolder holder, int position) { Msg msg = msgList.get(position); if (msg.getType() == Msg.TYPE_RECEIVE) { holder.leftLayout.setVisibility(View.VISIBLE); holder.rightLayout.setVisibility(View.GONE); holder.leftMsg.setText(msg.getContent()); } else if (msg.getType() == Msg.TYPE_SEND) { holder.rightLayout.setVisibility(View.VISIBLE); holder.leftLayout.setVisibility(View.GONE); holder.rightMsg.setText(msg.getContent()); } } public MsgAdapter(List<Msg> msgs) { this.msgList = msgs; } @Override public int getItemCount() { return msgList.size(); } static class ViewHolder extends RecyclerView.ViewHolder { LinearLayout leftLayout; LinearLayout rightLayout; TextView leftMsg; TextView rightMsg; ViewHolder(View view) { super(view); //这里要分为左边对话框 leftLayout = (LinearLayout) view.findViewById(R.id.left_layout); //这里要分为右边对话框 rightLayout = (LinearLayout) view.findViewById(R.id.right_layout); //这里要分为左边消息 leftMsg = (TextView) view.findViewById(R.id.left_msg); //这里要分为右边消息 rightMsg = (TextView) view.findViewById(R.id.right_msg); } }}最后这里附上聊天Activity的代码，中间主要实现了socket连接、发送，在输入图片是，对图片的转换，这
里的将图片显示在编辑框中方法也写在了该activity中，接收服务器的图片再经过转化后才能在对话框中将图
片显示出来，这里注意，获取到的图片内容，并不是图片本身，而是用一个与图片资源对应的字符串数组来
替代图片，但是编辑框和对话框并不能通过string将图片展示出来，需要将之先转化为spannerString，但是
我们最好收到服务器的图片显示的时候，使用handler传输时，进行传值时，必须用CharSequence而不是
String ,说的乱七八糟，具体大家看代码吧。**关键点就是编辑框、对话框不能直接显示图片，它们只能显示
String，所以要将图片先转化对应的SpannerString传到对话框中才能显示，这是个人笨拙的简易理解，应
该有错误**
