Question

我想问一下纠正我的问题。我看到一篇文章教会如何使用文本到语音安卓代码，但我遵循代码，我的AVD似乎没有响应。所以我去了另一个代码并输入，avd似乎也没有响应。有人可以帮我检查错误吗？

@Override

    super.onCreate(savedInstanceState);

    Toast.makeText(getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show();
    tts.speak(toSpeak,TextToSpeech.QUEUE_FLUSH,null);
}


@Override

    // 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 super.onOptionsItemSelected(item);
}

@Override

    // TODO Auto-generated method stub

}

Answer 1

第一个错误是你没有在onCreate中初始化你的按钮，也没有给它一个OnClickListener。这里的另一个问题是您的onInit。当你覆盖它时，尝试这样解决：

@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!");
        }
    }

并且整个代码看起来像这样：

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);
    }
}

Answer 2

我发现的错误很少： -

您不需要实现onInitListener并覆盖onInit（）方法，因为您正在使用它并且已经覆盖了OnCreate（）方法。
在OnCreate（）中的onInit（）之后你需要调用speakText（）方法。

speakText（inputText的）
