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： ```groovy 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： ```java 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： ```java 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： ```java 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： ```java 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： ```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： ```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： ```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： ```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： ```xml <uses-permission android:name="android.permission.INTERNET" /> ```
