我正在尝试编写一个应用程序，它应该说出我在这里给出的任何字符串是我的代码......有什么问题让我知道请告诉我......当我运行这段代码时，我得到了android.speech。 tts.TextToSpeech 服务未在 logcat 中启动错误。
注意：我已经从 Google play 安装了 TTS
public class MainActivity extends Activity implements TextToSpeech.OnInitListener {
private TextToSpeech tts;
private final int MY_VOICE_CHECK_CODE = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent voiceCheckIntent = new Intent();
// Intiating voice Recognizer
voiceCheckIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(voiceCheckIntent, MY_VOICE_CHECK_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case MY_VOICE_CHECK_CODE: {
if (requestCode == MY_VOICE_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// On Success, create the TTS(Text To Speech Synthesizer)
// instance
tts = new TextToSpeech(this, (TextToSpeech.OnInitListener) this);
speakOut("hello world");
} else {
// missing data, install it, This will give connection to
// Google play(TTS data)
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
break;
}
default:
break;
}
}
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
} else {
}
}
private void speakOut(String text) {
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
@Override
protected void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
}
