【问题描述】:
我的代码:
import java.math.BigInteger;
import java.security.SecureRandom;
import java.util.HashMap;
import java.util.Locale;
import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.speech.tts.UtteranceProgressListener;
import android.widget.Toast;
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)
@SuppressLint("NewApi")
public class MainActivity extends Activity {
public TextToSpeech tts;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tts = new TextToSpeech(this, new ttsInitListener());
}
@SuppressLint("TrulyRandom") class ttsInitListener implements OnInitListener {
@SuppressWarnings("deprecation")
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
tts.setLanguage(Locale.getDefault());
if (!tts.isSpeaking()) {
SecureRandom random = new SecureRandom();
String aa= new BigInteger(130, random).toString(32);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, aa);
tts.speak("Hello Hello HEllo HEllo HEllo",
TextToSpeech.QUEUE_FLUSH, map);
tts.setOnUtteranceProgressListener(new ttsUtteranceListener());
}
} else {
tts = null;
Toast.makeText(getApplicationContext(),
"Failed to initialize TTS engine.", Toast.LENGTH_SHORT)
.show();
}
}
}
class ttsUtteranceListener extends UtteranceProgressListener {
@Override
public void onDone(String utteranceId) {
Toast.makeText(getApplicationContext(), "onDone", Toast.LENGTH_LONG).show();
}
@Override
public void onError(String utteranceId) {
Toast.makeText(getApplicationContext(), "onError", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(String utteranceId) {
Toast.makeText(getApplicationContext(), "onStart", Toast.LENGTH_LONG).show();
}
}
}
说话时
tts.speak("Hello Hello HEllo HEllo HEllo",
TextToSpeech.QUEUE_FLUSH, map);
Finish 然后应该调用ttsUtteranceListener 类的onDone(String utteranceId) 方法。但并不总是到达ttsUtteranceListener。
为什么没有达到这个等级?
【问题讨论】:
-
您是否调试过
String aa= new BigInteger(130, random).toString(32);中创建的内容?尝试使用静态参数一次。 -
之前,我使用 map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "abc");
-
尝试输入
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "hello");,因为您的文本不包含 abc 而是 hello。 -
因为 UtteranceProgressListener 用于监听特定文本的话语进度。如果 文本被说出,它将被触发。
-
SecureRandom random = new SecureRandom(); String aa= new BigInteger(5, random).toString(32);字符串 abc="abc"+aa; Toast.makeText(_mContext, "value:"+abc, Toast.LENGTH_LONG).show(); HashMap
map = new HashMap (); map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, abc);
