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;}@Overridepublic void onReceiveServicePid(Context context, int i) {}@Overridepublic 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@Overridepublic 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@Overridepublic IBinder onBind(Intent intent) {return new MyGeTui();}public class MyGeTui extends Binder{public DemoIntentService get(){return DemoIntentService.this;}}@Overridepublic void onReceiveOnlineState(Context context, boolean b) {}@Overridepublic void onReceiveCommandResult(Context context, GTCmdMessage gtCmdMessage) {}@Overridepublic void onNotificationMessageArrived(Context context, GTNotificationMessage gtNotificationMessage) {}@Overridepublic 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"><LinearLayoutandroid:id="@+id/left_layout"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="left"android:background="@drawable/message_left"><TextViewandroid:id="@+id/left_msg"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"android:layout_margin="10dp" /></LinearLayout><LinearLayoutandroid:id="@+id/right_layout"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="right"android:background="@drawable/message_right"><TextViewandroid: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;}@Overridepublic ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = LayoutInflater.from( parent.getContext() ).inflate( R.layout.message_item, parent, false );return new ViewHolder( view );}@Overridepublic 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;}}@Overridepublic 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.RecyclerViewandroid:id="@+id/msg_recycler_view"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"/><LinearLayoutandroid:layout_width="match_parent"android:orientation="horizontal"android:layout_height="wrap_content"><EditTextandroid:id="@+id/message_text"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"android:hint="Type Something Here"/><Buttonandroid:id="@+id/message_send"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="发送" /></LinearLayout></LinearLayout>

MessageFragment.java
