[AndroidTips]调用TextToSpeech朗读的时候如何中间停顿
TTS在句子中间会停顿，你也可以通过在任何字符串中加点"."后面加空格来达到目的。最多可以有三个点，最后一个点后面加空格，没有空格可能不起作用。点越多停顿时间越长。
下面的代码中在一开始有一个长的停顿，然后在读消息体之前也有一个停顿：
private final BroadcastReceiver SMScatcher = new BroadcastReceiver() {
@Override
public void onReceive(final Context context, final Intent intent) {
if (intent.getAction().equals(
"android.provider.Telephony.SMS_RECEIVED")) {
// if(message starts with SMStretcher recognize BYTE)
StringBuilder sb = new StringBuilder();
/*
* The SMS-Messages are 'hiding' within the extras of the
* Intent.
*/
Bundle bundle = intent.getExtras();
if (bundle != null) {
/* Get all messages contained in the Intent */
Object[] pdusObj = (Object[]) bundle.get("pdus");
SmsMessage[] messages = new SmsMessage[pdusObj.length];
for (int i = 0; i < pdusObj.length; i++) {
messages[i] = SmsMessage
.createFromPdu((byte[]) pdusObj[i]);
}
/* Feed the StringBuilder with all Messages found. */
for (SmsMessage currentMessage : messages) {
// periods are to pause
sb.append("... Message From: ");
/* Sender-Number */
sb.append(currentMessage.getDisplayOriginatingAddress());
sb.append(".. ");
/* Actual Message-Content */
sb.append(currentMessage.getDisplayMessageBody());
}
// Toast.makeText(application, sb.toString(),
// Toast.LENGTH_LONG).show();
if (mTtsReady) {
try {
mTts.speak(sb.toString(), TextToSpeech.QUEUE_ADD,
null);
} catch (Exception e) {
Toast.makeText(application, "TTS Not ready",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
}
}
}
};
