Android Studio實現智能聊天
本文實例為大傢分享瞭Android Studio實現智能聊天的具體代碼,供大傢參考,具體內容如下
1、佈局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="發送"/> </LinearLayout> </LinearLayout>
2、創建子佈局msg_item,顯示聊天對話框
<?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、創建類Msg獲取數據
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、創建RecyclerView的適配器,MsgAdapter繼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、創建 RobotManager類封裝網絡,網絡地址:青雲客,智能聊天機器人
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、邏輯
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) { //獲取解析數據,顯示在Recycle中 Bundle data = msg.getData(); String result = data.getString("result"); Msg msg_get = new Msg(result, Msg.MSG_RECEIVED); msgList.add(msg_get); //數據刷新 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();//初始化數據 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(); //發起網絡請求 } }); } private void getInter() { //開起線程 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,解析獲得的數據 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,將解析的數據保存到 Message中,傳遞到主線程中顯示 Bundle data=new Bundle(); Message msg1=new Message(); if (msg.getType()==0){ data.putString("result",msg.getContent()); }else { data.putString("result","我不知道你在說什麼!"); } 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,快來和我聊天吧!", Msg.MSG_RECEIVED); msgList.add(msg); } }
