以上代码用androidstudio怎么写

以下是在 Android Studio 中实现类似功能的示例代码：
1. 在项目的 build.gradle 文件中添加以下依赖：

dependencies {
    implementation 'com.vdurmont:emoji-java:5.1.1'
    implementation 'com.squareup.okhttp3:okhttp:4.9.1'
    implementation 'com.squareup.okio:okio:2.10.0'
    implementation 'com.google.code.gson:gson:2.8.7'
}

2. 创建一个 ChatActivity 类，用于展示聊天界面和处理用户输入和 AI 回复：

public class ChatActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private ChatAdapter mAdapter;
    private EditText mEditText;
    private Button mSendButton;

    private final OkHttpClient mClient = new OkHttpClient();
    private final Gson mGson = new Gson();
    private final EmojiParser mEmojiParser = EmojiParser.getInstance();

    private static final String BASE_URL = "https://api.chitgpt.com/ask";
    private static final int MSG_TYPE_USER = 1;
    private static final int MSG_TYPE_BOT = 2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chat);

        mRecyclerView = findViewById(R.id.recycler_view);
        mEditText = findViewById(R.id.edit_text);
        mSendButton = findViewById(R.id.send_button);

        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        mAdapter = new ChatAdapter(new ArrayList<>());
        mRecyclerView.setAdapter(mAdapter);

        mSendButton.setOnClickListener(view -> {
            String text = mEditText.getText().toString().trim();
            if (!text.isEmpty()) {
                sendMessage(text);
                mEditText.setText("");
            }
        });
    }

    private void sendMessage(String text) {
        mAdapter.addMessage(new Message(text, MSG_TYPE_USER));
        mRecyclerView.smoothScrollToPosition(mAdapter.getItemCount());

        String url = BASE_URL + "?question=" + Uri.encode(text);
        Request request = new Request.Builder()
                .url(url)
                .build();

        mClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                e.printStackTrace();
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (response.isSuccessful()) {
                    String json = response.body().string();
                    BotResponse botResponse = mGson.fromJson(json, BotResponse.class);
                    String reply = botResponse.getAnswer();
                    reply = mEmojiParser.replaceInText(reply);

                    runOnUiThread(() -> {
                        mAdapter.addMessage(new Message(reply, MSG_TYPE_BOT));
                        mRecyclerView.smoothScrollToPosition(mAdapter.getItemCount());
                    });
                }
            }
        });
    }
}

3. 创建一个 ChatAdapter 类，用于展示聊天记录：

public class ChatAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private List<Message> mMessages;

    public ChatAdapter(List<Message> messages) {
        mMessages = messages;
    }

    public void addMessage(Message message) {
        mMessages.add(message);
        notifyItemInserted(mMessages.size() - 1);
    }

    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view;

        if (viewType == ChatActivity.MSG_TYPE_USER) {
            view = inflater.inflate(R.layout.item_message_user, parent, false);
            return new UserViewHolder(view);
        } else {
            view = inflater.inflate(R.layout.item_message_bot, parent, false);
            return new BotViewHolder(view);
        }
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
        Message message = mMessages.get(position);

        if (holder instanceof UserViewHolder) {
            ((UserViewHolder) holder).bind(message);
        } else {
            ((BotViewHolder) holder).bind(message);
        }
    }

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

    @Override
    public int getItemViewType(int position) {
        return mMessages.get(position).getType();
    }

    private static class UserViewHolder extends RecyclerView.ViewHolder {
        private TextView mTextView;

        public UserViewHolder(@NonNull View itemView) {
            super(itemView);
            mTextView = itemView.findViewById(R.id.text_view);
        }

        public void bind(Message message) {
            mTextView.setText(message.getText());
        }
    }

    private static class BotViewHolder extends RecyclerView.ViewHolder {
        private TextView mTextView;

        public BotViewHolder(@NonNull View itemView) {
            super(itemView);
            mTextView = itemView.findViewById(R.id.text_view);
        }

        public void bind(Message message) {
            mTextView.setText(message.getText());
        }
    }
}

4. 创建一个 Message 类，用于表示一条聊天记录：

public class Message {
    private String mText;
    private int mType;

    public Message(String text, int type) {
        mText = text;
        mType = type;
    }

    public String getText() {
        return mText;
    }

    public int getType() {
        return mType;
    }
}

5. 创建一个 BotResponse 类，用于解析 AI 的回复：

public class BotResponse {
    @SerializedName("answer")
    private String mAnswer;

    public String getAnswer() {
        return mAnswer;
    }
}

6. 在 res/layout 目录下创建两个布局文件，分别用于展示用户输入和 AI 回复：

item_message_user.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_message_user"
    android:padding="16dp"
    android:textColor="#FFFFFF" />

item_message_bot.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_message_bot"
    android:padding="16dp"
    android:textColor="#000000" />

7. 在 res/drawable 目录下创建两个形状文件，用于设置聊天气泡的样式：

bg_message_user.xml：

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="8dp" />
    <solid android:color="#2979FF" />
</shape>

bg_message_bot.xml：

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="8dp" />
    <solid android:color="#FFFFFF" />
    <stroke
        android:width="1dp"
        android:color="#E0E0E0" />
</shape>

8. 最后，在 AndroidManifest.xml 文件中添加以下权限：

<uses-permission android:name="android.permission.INTERNET" />

这样，一个简单的聊天界面就实现了。当用户输入文本后，应用将其发送给 ChitGPT API，获取 AI 的回复，并将聊天记录展示在 RecyclerView 中。
