Android Studio-个推-实现简单聊天(三)

因为之前的是写的主要代码，现在贴出全部代码，有些瑕疵，哈哈哈哈。那我现在开始贴代码吧

1.聊天实体类
（1）聊天实体类
ChatUser.java

package com.smxy.lj.chat;

import java.io.Serializable;

public class ChatUser implements Serializable {
    private String cid;
    private String msg;

    public ChatUser() {
    }

    public ChatUser(String cid, String msg) {
        this.cid = cid;
        this.msg = msg;
    }

    public String getCid() {
        return cid;
    }

    public void setCid(String cid) {
        this.cid = cid;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }
}

（2）聊天界面实体类

package com.smxy.lj.message;

public class Message {
    public static final int TYPE_RECEIVED = 0;//消息类型-收到的消息
    public static final int TYPE_SENT = 1;//消息类型-发出的消息

    private String content; //消息内容
    private int type;//消息类型

    public Message(String content, int type) {
        this.content = content;
        this.type = type;
    }

    public String getContent() {
        return content;
    }

    public int getType() {
        return type;
    }
}

（3）个推服务类
DemoIntentService.java

package com.smxy.lj.chat;

import android.content.Context;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.util.Log;

import com.igexin.sdk.GTIntentService;
import com.igexin.sdk.message.GTCmdMessage;
import com.igexin.sdk.message.GTNotificationMessage;
import com.igexin.sdk.message.GTTransmitMessage;
import com.smxy.lj.utils.MyLog;
import com.smxy.lj.utils.SharedPreferencesHelper;

/**
 * 继承 GTIntentService 接收来自个推的消息, 所有消息在线程中回调, 如果注册了该服务, 则务必要在 AndroidManifest中声明, 否则无法接受消息<br>
 * onReceiveMessageData 处理透传消息<br>
 * onReceiveClientId 接收 cid <br>
 * onReceiveOnlineState cid 离线上线通知 <br>
 * onReceiveCommandResult 各种事件处理回执 <br>
 */
public class DemoIntentService extends GTIntentService {

    SharedPreferencesHelper sharedPreferencesHelper ;
    private OnProgressListener onProgressListener;

    public void setOnProgressListener(OnProgressListener onProgressListener) {
        this.onProgressListener = onProgressListener;
    }

    @Override
    public void onReceiveServicePid(Context context, int i) {

    }

    @Override
    public void onReceiveClientId(Context context, String clientid) {
        Log.e(TAG, "onReceiveClientId -> " + "clientid = " + clientid);
        sharedPreferencesHelper = new SharedPreferencesHelper(getApplicationContext(),"push_CID");
        sharedPreferencesHelper.put("cid",clientid);
        //MyLog.e("CID="+ sharedPreferencesHelper.getSharedPreference("cid",null));
    }

    //接收消息 ---透传
    @Override
    public void onReceiveMessageData(Context context, GTTransmitMessage gtTransmitMessage) {
        Log.e(TAG, "onReceiveMessageData -> " + "message = " + new String(gtTransmitMessage.getPayload()));
        if (onProgressListener!=null){
            onProgressListener.onProgress(new String(gtTransmitMessage.getPayload()));
        }
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return new MyGeTui();
    }

    public class MyGeTui extends Binder{
        public DemoIntentService get(){
            return DemoIntentService.this;
        }
    }

    @Override
    public void onReceiveOnlineState(Context context, boolean b) {

    }

    @Override
    public void onReceiveCommandResult(Context context, GTCmdMessage gtCmdMessage) {

    }


    @Override
    public void onNotificationMessageArrived(Context context, GTNotificationMessage gtNotificationMessage) {

    }

    @Override
    public void onNotificationMessageClicked(Context context, GTNotificationMessage gtNotificationMessage) {

    }
   //回调，将接收的内容传到主界面
    public interface OnProgressListener {
         void onProgress(String  progress);
     }
}

2.首先是聊天界面
（1）写聊天界面的adapter

message_adapter.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="10dp">

    <LinearLayout
        android:id="@+id/left_layout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:background="@drawable/message_left">

        <TextView
            android:id="@+id/left_msg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_margin="10dp" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/right_layout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:background="@drawable/message_right">

        <TextView
            android:id="@+id/right_msg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_margin="10dp" />
    </LinearLayout>

</LinearLayout>

MsgAdapter.java

package com.smxy.lj.message;

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 com.smxy.lj.officedemo.R;

import org.w3c.dom.Text;

import java.util.List;

public class MsgAdapter extends RecyclerView.Adapter<MsgAdapter.ViewHolder> {

    private List<Message> mMsgList;


    static class ViewHolder extends RecyclerView.ViewHolder {
        LinearLayout leftLayout, rightLayout;
        TextView leftMsg, rightMsg;

        public ViewHolder(View view) {
            super( view );
            leftLayout = view.findViewById( R.id.left_layout );
            rightLayout = view.findViewById( R.id.right_layout );
            leftMsg = view.findViewById( R.id.left_msg );
            rightMsg = view.findViewById( R.id.right_msg );
        }
    }

    public MsgAdapter(List<Message> mMsgList) {//构造方法
        this.mMsgList = mMsgList;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View view = LayoutInflater.from( parent.getContext() ).inflate( R.layout.message_item, parent, false );
        return new ViewHolder( view );
    }

    @Override
    public void onBindViewHolder(MsgAdapter.ViewHolder holder, int position) {

        Message msg = mMsgList.get( position );
        switch (msg.getType()) {
            //收到消息，显示左边布局，隐藏右边布局
            case Message.TYPE_RECEIVED:
                holder.leftLayout.setVisibility( View.VISIBLE );
                holder.rightLayout.setVisibility( View.GONE );
                holder.leftMsg.setText( msg.getContent() );
                break;
            //发送消息，显示右边布局，隐藏左边布局
            case Message.TYPE_SENT:
                holder.leftLayout.setVisibility( View.GONE );
                holder.rightLayout.setVisibility( View.VISIBLE );
                holder.rightMsg.setText( msg.getContent() );
                break;
            default:
                break;
        }

    }

    @Override
    public int getItemCount() {
        return mMsgList.size();
    }
}

（2）聊天界面

memo_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/msg_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:orientation="horizontal"
        android:layout_height="wrap_content">

        <EditText
            android:id="@+id/message_text"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:hint="Type Something Here"
             />

        <Button
            android:id="@+id/message_send"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="发送" />

    </LinearLayout>


</LinearLayout>
