Java 简单的TextToSpeech代码,java,android,Java,Android,我想做一个简单的TextToSpeechcode。我的代码在这里： TextToSpeech tts = new TextToSpeech(this, this); tts.setLanguage(Locale.US); tts.speak("This is a Alert Application", TextToSpeech.QUEUE_ADD,null,null); 但我得到了这个错误： Error:(100, 28) error: no suitable constructor foun

我想做一个简单的

TextToSpeech

code。我的代码在这里：

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("This is a Alert Application", TextToSpeech.QUEUE_ADD,null,null);

但我得到了这个错误：

Error:(100, 28) error: no suitable constructor found for TextToSpeech(MainActivity,MainActivity)
constructor TextToSpeech.TextToSpeech(Context,OnInitListener,String) is not applicable
(actual and formal argument lists differ in length)
constructor TextToSpeech.TextToSpeech(Context,OnInitListener) is not applicable
(actual argument MainActivity cannot be converted to OnInitListener by method invocation conversion)

我错过了什么？我需要在代码中输入什么？

将活动按以下方式实施：

  public class AndroidTextToSpeech extends Activity implements TextToSpeech.OnInitListener {

在错误输出中，您必须按照建议使用有效参数初始化TextToSpeech对象，提供

上下文

和

OnInitListener

对象

这是一个初始化示例（希望有帮助）：

}

如果允许一个线程睡眠并且睡眠后正在调用tts.speak（），请尝试上面的代码。如果是这样的话，在查看代码的时候，tts似乎没有初始化，并且为空，因此会出现异常崩溃

这段代码应该可以防止异常，但是如果TTS引擎的初始化花费太长时间，那么您就不能让它说是加载。另外，我猜5秒（顺便说一句，这是一个很长的时间）睡眠是为了让它得到初始化

代码

这是我目前的代码：

包com.example.texttospeech

    import java.util.Locale;

    import android.os.Bundle;
    import android.app.Activity;
    import android.content.SharedPreferences.Editor;
    import android.speech.tts.TextToSpeech;
    import android.util.Log;
    import android.view.Menu;
    import android.view.View;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

公共类MainActivity扩展活动实现TextToSpeech.OnInitListener{

private int result = 0;
private TextToSpeech tts;
private Button btnSpeak;
private EditText txtText;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    tts = new TextToSpeech(this, this);
    btnSpeak = (Button) findViewById(R.id.btnSpeak);
    txtText = (EditText) findViewById(R.id.txtText);
    // button on click event
    btnSpeak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            speakOut();
        }
    });
}

// shutdown tts when activity destroy
@Override
public void onDestroy() {
    // Don't forget to shutdown!
    if (tts != null) {
        tts.stop();
        tts.shutdown();
    }
    super.onDestroy();
}

// It will called before TTS started
@Override
public void onInit(int status) {
    // TODO Auto-generated method stub
    // check status for TTS is initialized or not
    if (status == TextToSpeech.SUCCESS) {
        // if TTS initialized than set language
        result = tts.setLanguage(Locale.US);

        // tts.setPitch(5); // you can set pitch level
        // tts.setSpeechRate(); //you can set speech speed rate

        // check language is supported or not
        // check language data is available or not
        if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Toast.makeText(this, "Missing data", Toast.LENGTH_LONG).show();
            // disable button
            btnSpeak.setEnabled(false);
        } else {
            // if all is good than enable button convert text to speech
            btnSpeak.setEnabled(true);
        }
    } else {
        Log.e("TTS", "Initilization Failed");
    }
}

// call this method to speak text
private void speakOut() {
    String text = txtText.getText().toString();
    if (result != tts.setLanguage(Locale.US)) {
        Toast.makeText(getApplicationContext(), "Enter right Words...... ", Toast.LENGTH_LONG).show();
    } else {
        // speak given text
        tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
    }
}

}

speak已被弃用

implements activity with oninitlistener能否向我们展示完整的代码？从类开始，creationI没有创建类。我觉得这已经足够了。我错过了什么？我只想在应用程序启动时谈论一下“这是一个警报应用程序”。一切就绪：

公共类AndroidTextToSpeech扩展活动实现TextToSpeech.OnInitListener{TextToSpeech tts=new TextToSpeech（This，This）；tts.setLanguage（Locale.US）；tts.speak(“这是一个警报应用程序”，TextToSpeech.QUEUE_ADD，null，null）；}

但现在setLanguage和speak是红色的，无法解析符号。您是否允许线程睡眠，睡眠后是否调用tts.speak（）。如果是这样的话，此时查看您的代码，tts似乎没有初始化，并且为空，因此会出现异常崩溃。我尝试了此应用程序，但当我编写一个句子，然后单击speak按钮时，应用程序崩溃。speak已弃用。我想在Android ICS 4.0.1中尝试。问题是，当我构建应用程序时没有错误，但speak是w我在一个虚拟机中使用Android Studio，然后制作apk并将apk导出到手机。我看不到更多的错误。virtul设备是否有扬声器？为什么要在上面测试…！！在手机上试用。
