1、布局activit_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">
 
    <androidx.recyclerview.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/recycle">
 
 
    </androidx.recyclerview.widget.RecyclerView>
 
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
 
        <EditText
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:id="@+id/input"/>
 
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/send"
            android:text="发送"/>
    </LinearLayout>

</LinearLayout>

2、创建子布局msg_item，显示聊天对话框

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:padding="10dp"
    android:layout_height="wrap_content">
 
 
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/left_layout"
        android:layout_gravity="left"
        android:background="@drawable/message_left">
 
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:layout_marginTop="10dp"
            android:id="@+id/left_msg"/>
    </LinearLayout>
 
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/right_layout"
        android:layout_gravity="right"
        android:layout_marginLeft="10dp"
        android:background="@drawable/message_right">
 
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:layout_marginTop="10dp"
            android:id="@+id/right_msg"/>
</LinearLayout>

3、创建类Msg获取数据

public class Msg {
 
    public static final int MSG_RECEIVED = 0;
    public static final int MSG_SEND =1 ;
 
    private String content;
    private int type;
 
    public Msg(String content,int type){
        this.content=content;
        this.type=type;
    }
 
    public String getContent() {
        return content;
    }
 
    public int getType() {
        return type;
    }
}

4、创建RecyclerView的适配器，MsgAdapter继RecyclerView.Adapter<MsgAdapter.ViewHolder>

 public class MsgAdapter extends RecyclerView.Adapter<MsgAdapter.ViewHolder> {
    private List<Msg> mMsgList;
 
    public class ViewHolder extends RecyclerView.ViewHolder {
 
        LinearLayout leftLayout;
        TextView leftMsg;
        LinearLayout rightLayout;
        TextView rightMsg;
 
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
 
            leftLayout=itemView.findViewById(R.id.left_layout);
            rightLayout=itemView.findViewById(R.id.right_layout);
            leftMsg=itemView.findViewById(R.id.left_msg);
            rightMsg=itemView.findViewById(R.id.right_msg);
 
        }
    }
 
    public MsgAdapter(List<Msg> msgList){
        mMsgList=msgList;
    }
    @NonNull
    @Override
    public MsgAdapter.ViewHolder onCreateViewHolder(@NonNull 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(@NonNull MsgAdapter.ViewHolder holder, int position) {
        Msg msg=mMsgList.get(position);
 
        if (msg.getType()==Msg.MSG_RECEIVED){
            holder.leftLayout.setVisibility(View.VISIBLE);
            holder.rightLayout.setVisibility(View.GONE);
            holder.leftMsg.setText(msg.getContent());
        }else if (msg.getType()==Msg.MSG_SEND){
            holder.leftLayout.setVisibility(View.GONE);
            holder.rightLayout.setVisibility(View.VISIBLE);
            holder.rightMsg.setText(msg.getContent());
 
        }
 
    }
 
    @Override
    public int getItemCount() {
        return mMsgList.size();
    }

5、创建 RobotManager类封装网络，网络地址：青云客，智能聊天机器人

public class RobotManager {
    private static String Url="http://api.qingyunke.com/api.php?key=free&appid=0&msg=!!";
 
    public static String getUrl(String question){
        String real_Url=Url.replace("!!",question);
        return real_Url;
    }
}

6、逻辑

public class MainActivity extends AppCompatActivity {
    private static String TAG="MainActivity";
 
 
    private List<Msg> msgList = new ArrayList<>();
    private EditText input;
    private RecyclerView recyclerView;
    private LinearLayoutManager manager;
    private Button button;
    private MsgAdapter adapter;
    private String input_text;
    private StringBuilder response;
 
    private Handler handler = new Handler() {
    @Override
        public void handleMessage(Message msg) {
            //获取解析数据，显示在Recycle中
            Bundle data = msg.getData();
            String result = data.getString("result");
 
            Msg msg_get = new Msg(result, Msg.MSG_RECEIVED);
            msgList.add(msg_get);
                
                //数据刷新
            adapter.notifyItemInserted(msgList.size() - 1);
            recyclerView.scrollToPosition(msgList.size() - 1);
 
 
        }
 
 
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
 
        initMsg();//初始化数据
 
 
        recyclerView = findViewById(R.id.recycle);
        button = findViewById(R.id.send);
        input = findViewById(R.id.input);
 
        manager = new LinearLayoutManager(this);
        recyclerView.setLayoutManager(manager);
        adapter = new MsgAdapter(msgList);
        recyclerView.setAdapter(adapter);
 
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                input_text = input.getText().toString();
                Msg msg = new Msg(input_text, Msg.MSG_SEND);
                msgList.add(msg);
 
                adapter.notifyItemInserted(msgList.size() - 1);
                recyclerView.scrollToPosition(msgList.size() - 1);
                input.setText("");
 
                getInter();   //发起网络请求
 
            }
 
        });
 
    }
 
 
    private void getInter() {
        //开起线程
        new Thread(new Runnable() {
            @Override
            public void run() {
                HttpURLConnection connection = null;
                BufferedReader reader = null;
                try {
                    URL url = new URL(RobotManager.getUrl(input_text));
                    connection = (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("GET");
                    connection.setReadTimeout(8000);
                    connection.setConnectTimeout(8000);
 
                    InputStream in = connection.getInputStream();
 
                    reader = new BufferedReader(new InputStreamReader(in));
                    StringBuilder response = new StringBuilder();
                    String line = "";
                    while ((line = reader.readLine()) != null) {
                        response.append(line);
                    }
 
                    // 2,解析获得的数据
                    Gson gson=new Gson();
                    Msg msg=gson.fromJson(response.toString(),Msg.class);
                    Log.d(TAG, "result:" + msg.getType());
                    Log.d(TAG, "content:" + msg.getContent());
 
 
                    // 3，将解析的数据保存到 Message中，传递到主线程中显示
                    Bundle data=new Bundle();
                    Message msg1=new Message();
                    if (msg.getType()==0){
                        data.putString("result",msg.getContent());
                    }else {
                        data.putString("result","我不知道你在说什么！");
                    }
                    msg1.setData(data);
                    msg1.what=1;
                    handler.sendMessage(msg1);

 
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (ProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    if (reader != null) {
                        try {
                            reader.close();
 
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                    if (connection != null) {
                        connection.disconnect();
                    }
                }
            }
 
 
        }).start();
    }
 
 
    private void initMsg() {
        Msg msg = new Msg("我是菲菲，快来和我聊天吧！", Msg.MSG_RECEIVED);
        msgList.add(msg);
    }
}
