안드로이드에서 tts 엔진을 사용하는 방법을 알고 싶기 때문에이 앱을 작성했습니다. 나는 내 전화 및 에뮬레이터에 얻을 응용 프로그램을 시작할 때android text to speech (tts)
는 그러나 "unfortanetly 앱이 들렸다해야한다", 나는 또한 로그 캣 첨부, 내가 여기에 누군가가 나에게
package com.example.textspeechdemi;
import java.util.Locale;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.speech.tts.TextToSpeech;
import android.view.Menu;
import android.widget.Toast;
public class MainActivity extends Activity implements TextToSpeech.OnInitListener {
Intent mIntent;
String value;
private TextToSpeech tts;
int j;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mIntent = getIntent();
Bundle b = getIntent().getExtras();
final String name = b.getString("name");
j = name.toCharArray()[0];
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, RESULT_OK);
tts = new TextToSpeech(this, this);
tts.speak("Welcome", TextToSpeech.QUEUE_ADD, null);
final Thread t1 = new Thread() {
public void run() {
try {
Thread.sleep(10000);
finish();
// this.destroy();
} catch (Exception e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_SHORT).show();
}
}
};
t1.start();
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RESULT_OK) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
tts = new TextToSpeech(this, this);
} else {
// missing data, install it
Intent installIntent = new Intent();
installIntent
.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
Toast.makeText(this,
"Write and Listen engine is initialized & Ready",
Toast.LENGTH_LONG).show();
} else if (status == TextToSpeech.ERROR) {
Toast.makeText(this,
"Error occurred while initializing Text-To-Speech engine",
Toast.LENGTH_LONG).show();
}
}
protected void onDestroy() {
super.onDestroy();
if (tts != null) {
tts.shutdown();
}
}
}
