文本到语音的android代码

Question

我想问一下关于我的问题的更正。我看到一篇文章，教导如何使用文本来演讲android代码，但是我遵循了代码，而我的AVD似乎没有回应。所以我去了另一个代码并输入，avd似乎也没有回应。有人可以帮我检查错误吗？

@Override

    super.onCreate(savedInstanceState);

    new TextToSpeech.OnInitListener(){

      if(status!=TextToSpeech.ERROR){ 
       tts.setLanguage(Locale.UK);} 
      } 
     }); 
    } 

@Override

     tts.shutdown();

    super.onPause();

    getMenuInflater().inflate(R.menu.main, menu);

    String toSpeak=inputText.getText().toString(); 
    Toast.makeText(getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show(); 
    tts.speak(toSpeak,TextToSpeech.QUEUE_FLUSH,null); 
} 


@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml.

     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

@Override 
public void onInit(int status) { 
    // TODO Auto-generated method stub 

}

第一个错误是，你还没有初始化你的按钮在onCreate，也没有给你一个OnClickListener它。另一个问题是您的onInit。当你重写它，尝试围绕工作像这样：

@Override 
    public void onInit(int status) { 

     if (status == TextToSpeech.SUCCESS) { 

      int result = tts.setLanguage(Locale.UK); 

      if (result == TextToSpeech.LANG_MISSING_DATA 
        || result == TextToSpeech.LANG_NOT_SUPPORTED) { 
       Log.e("TTS", "This Language is not supported"); 
      } else { 
       button1.setEnabled(true); 
       speakText(); 
      } 

     } else { 
      Log.e("TTS", "Initilization Failed!"); 
     } 
    } 

和整个代码看起来是这样的：

public class MainActivity extends Activity implements 
     TextToSpeech.OnInitListener { 

    private TextToSpeech tts; 
    private Button speakButton; 
    private EditText inputText; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     inputText = (EditText) findViewById(R.id.editText1); 
     tts = new TextToSpeech(this, this); 

     speakButton = (Button) findViewById(R.id.button1); 
     // button on click event 
     speakButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       speakOut(); 
      } 

     }); 
    } 

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

    @Override 
    public void onInit(int status) { 

     if (status == TextToSpeech.SUCCESS) { 

      int result = tts.setLanguage(Locale.US); 

      if (result == TextToSpeech.LANG_MISSING_DATA 
        || result == TextToSpeech.LANG_NOT_SUPPORTED) { 
       Log.e("TTS", "This Language is not supported"); 
      } else { 
       speakButton.setEnabled(true); 
       speakText(); 
      } 

     } else { 
      Log.e("TTS", "Initilization Failed!"); 
     } 

    } 

    private void speakText() { 

     String toSpeak = inputText.getText().toString(); 

     tts.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null); 
    } 
}

有，我发现几个错误： -

1. 您不需要实现onInitListener并覆盖方法onInit（），因为您正在使用它一次，并且已经在OnCreate（）方法中重写。

2. onInit（）在OnCreate（）后需要调用sayText（）方法。

speakText（inputText的）
