本文实例为大家分享了android Studio实现智能聊天的具体代码,供大家参考,具体内容如下

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">

    <javascriptTextView
      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);
    androidrecyclerView.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);
  }
}
