android语音机器人代码,Android studio开发小型对话机器人app(实例代码)

以下是一个简单的Android语音机器人代码，使用Android Studio进行开发:

1. 创建一个新的Android Studio项目，命名为"VoiceRobot"。
2. 在build.gradle文件中添加以下依赖项:

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    //Speech Recognition Library
    implementation 'com.google.android.gms:play-services-speech:15.0.1'
}

3. 在activity_main.xml文件中添加以下布局:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/tv_result"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Result"
        app:layout_constraintBottom_toTopOf="@+id/btn_listen"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <Button
        android:id="@+id/btn_listen"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Listen"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tv_result" />

</android.support.constraint.ConstraintLayout>

4. 在MainActivity.java文件中添加以下代码:

import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.Locale;

public class MainActivity extends AppCompatActivity implements RecognitionListener {

    private SpeechRecognizer speechRecognizer;
    private Intent recognizerIntent;
    private TextView tvResult;
    private Button btnListen;

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

        tvResult=findViewById(R.id.tv_result);
        btnListen=findViewById(R.id.btn_listen);

        speechRecognizer=SpeechRecognizer.createSpeechRecognizer(this);
        recognizerIntent=new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());

        speechRecognizer.setRecognitionListener(this);

        btnListen.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                speechRecognizer.startListening(recognizerIntent);
            }
        });
    }

    @Override
    public void onReadyForSpeech(Bundle bundle) {

    }

    @Override
    public void onBeginningOfSpeech() {

    }

    @Override
    public void onRmsChanged(float v) {

    }

    @Override
    public void onBufferReceived(byte[] bytes) {

    }

    @Override
    public void onEndOfSpeech() {

    }

    @Override
    public void onError(int i) {

    }

    @Override
    public void onResults(Bundle bundle) {
        ArrayList<String> matches=bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        if(matches!=null) {
            tvResult.setText(matches.get(0));
        }
    }

    @Override
    public void onPartialResults(Bundle bundle) {

    }

    @Override
    public void onEvent(int i, Bundle bundle) {

    }
}

在这个代码中，我们创建了一个SpeechRecognizer对象来处理语音识别。我们使用RecognizerIntent来定义我们想要识别的语音，并使用Locale.getDefault()来设置默认语言。我们使用setRecognitionListener()方法来注册一个RecognitionListener对象，该对象用于接收语音识别结果。我们还创建了一个按钮，当点击时会启动语音识别，并在TextView中显示结果。最后我们实现了RecognitionListener接口，以接收语音识别结果。

这就是一个简单的Android语音机器人代码，希望对你有所帮助。
