TextToSpeech与API 21 [英] TextToSpeech with API 21

问题描述

有人可以提供帮助。 所有可用的例子是pcated版本21日$ P $

Can someone help me using TTS with API 21. All examples available are deprecated with version 21

这是我的code提供的最后一行的错误：

here's my code giving error on last line:

Calendar cal = Calendar.getInstance();
                    cal.getTime();
                    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
                    String text = sdf.toString();
                    btn.setText("Ouvir as Horas");

                    TextToSpeech tts = new TextToSpeech(NightClock.this,(TextToSpeech.OnInitListener) NightClock.this);
                    tts.setLanguage(Locale.US);
                    tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);

在Android开发它说，该方法是pcated并且由一个在底部取代德$ P $。 一个人可以帮到code我的应用程序。

In Android developers it says that this method is deprecated and replaced by the one on the bottom. Can someone help to code my app.

讲（字符串文本，诠释queueMode，HashMap的PARAMS） 这种方法去precated在API层面21. API级别21，通过代言取代（的CharSequence，INT，捆绑，字符串）。

speak(String text, int queueMode, HashMap params) This method was deprecated in API level 21. As of API level 21, replaced by speak(CharSequence, int, Bundle, String).

推荐答案

我搜查各种网站。最后，我想我可以得到答案的提问......

I searched various site. Finally, I think I could get the answer for your Question...

而不是调用tts.speak（）直接，把下面的if-else语句。

Instead calling tts.speak() directly, put the following if-else statement.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    ttsGreater21(text);
} else {
    ttsUnder20(text);
}

然后声明ttsGreater21（）和ttsUnder20（）如下：

Then declare ttsGreater21() and ttsUnder20() as follows.

@SuppressWarnings("deprecation")
private void ttsUnder20(String text) {
    HashMap<String, String> map = new HashMap<>();
    map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "MessageId");
    tts.speak(text, TextToSpeech.QUEUE_FLUSH, map);
}

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void ttsGreater21(String text) {
    String utteranceId=this.hashCode() + "";
    tts.speak(text, TextToSpeech.QUEUE_FLUSH, null, utteranceId);
}

我证实了上述code与Genymotion VM的Andr​​oid 5.0和Android 4.4.4。

I confirmed above code with Genymotion VM Android 5.0 and Android 4.4.4.
