Android学习之Socket多个客户端聊天布局

来源：互联网发布：java基础类型有哪些编辑：程序博客网时间：2024/06/07 18:38

服务器Socket接受到客户端发送的消息之后，转发给容器中的其他Socket，别的客户端接受到显示在左边，自己发的显示在右边。

消息类

public class Msg {    private String msg;    private int left_right;    public Msg(String msg,int left_right){        this.msg = msg;        this.left_right = left_right;    }    public String getMsg(){        return msg;    }    public int getLeft_right(){        return left_right;    }}

item布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="wrap_content">    <LinearLayout        android:id="@+id/left"        android:background="@drawable/messageleft"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="left">        <TextView            android:id="@+id/text_left"            android:textSize="16dp"            android:textColor="#000"            android:layout_width="wrap_content"            android:layout_height="wrap_content" />    </LinearLayout>    <LinearLayout        android:id="@+id/right"        android:layout_gravity="right"        android:background="@drawable/messageright"        android:layout_width="wrap_content"        android:layout_height="wrap_content">        <TextView            android:id="@+id/text_right"            android:textSize="16dp"            android:textColor="#000"            android:layout_width="wrap_content"            android:layout_height="wrap_content" />    </LinearLayout></LinearLayout>

适配器

public class MsgAdapter extends RecyclerView.Adapter<MsgAdapter.ViewHolder>{    private List<Msg> msgs;    private static final int MES_LEFT = 0,MES_RIGHT = 1;    static class ViewHolder extends RecyclerView.ViewHolder{        TextView text_left,text_right;        LinearLayout linearLayout_left,linearLayout_right;        public ViewHolder(View view){            super(view);            text_left = (TextView) view.findViewById(R.id.text_left);            text_right = (TextView) view.findViewById(R.id.text_right);            linearLayout_left = (LinearLayout) view.findViewById(R.id.left);            linearLayout_right = (LinearLayout) view.findViewById(R.id.right);        }    }    public MsgAdapter(List<Msg> msgs){        this.msgs = msgs;    }    @Override    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(parent.getContext())                .inflate(R.layout.msg_item,parent,false);        ViewHolder holder = new ViewHolder(view);        return  holder;    }    @Override    public void onBindViewHolder(ViewHolder holder, int position) {        Msg msg = msgs.get(position);        //如果显示左边，右边隐藏        if(msg.getLeft_right()==MES_LEFT) {            holder.text_left.setText(msg.getMsg());            holder.linearLayout_right.setVisibility(View.GONE);            holder.linearLayout_left.setVisibility(View.VISIBLE);        }        //如果显示右边，左边隐藏        else if(msg.getLeft_right()==MES_RIGHT){            holder.text_right.setText(msg.getMsg());            holder.linearLayout_left.setVisibility(View.GONE);            holder.linearLayout_right.setVisibility(View.VISIBLE);        }    }    @Override    public int getItemCount() {        return msgs.size();    }}
