问题描述

我已经开发了具有使用TTS引擎的应用程序。

i have developed an application which has to use TTS Engine.

现在的问题是,我需要等到TTS引擎被初始化,但我使用的睡眠方法时不尽如人意。

Now the problem is i need to wait till the TTS engine is initialized,though i am using sleep method it is not working well.

这是我的code

public void onCreate(Bundle savedInstanceState) {

    ......

    Intent checkin = new Intent();
    checkin.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkin, MY_DATA_CHECKCODE1);
    //l.setOnTouchListener(this);

    try {
        Thread.sleep(2000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

     tts.speak("Enter sms", TextToSpeech.QUEUE_FLUSH, null);

}


protected void onActivityResult(int requestCode, int resultCode, Intent data) {


if (requestCode == MY_DATA_CHECKCODE) {

if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {

// success, create the TTS instance

tts = new TextToSpeech(this, this);

tts.setLanguage(Locale.US);

tts.setSpeechRate((float) 0.4);


        } 
    }

}

代替上述的睡眠方法

我需要等到TTS引擎没有
initialized.so我怎么能写一个整洁块code,继续
后的当前活动TTS引擎被初始化,而不是做一个硬编码,以检查在一个循环是否TTS
已被初始化。(我甚至不知道如何做到这一点为好)。

instead of above sleep method i need to wait till the TTS Engine is not
initialized.so how can i write a neat block of code to resume the current activity after
TTS Engine is initialized, instead of doing a hard coding to check in a loop whether TTS
has been initialized.(i even dont know how to do this as well).

该应用程序在运行非响应状态,并抛出空指针异常

The application is running in to Non-responding state and throwing Null pointer Exception

当我使用

tts.speak("Enter sms", TextToSpeech.QUEUE_FLUSH, null);

方法。所以,请建议我的解决方案来解决这个问题。我用Google搜索,但没有找到任何合适的答案。

method. So please suggest me the solution to fix this problem. I have googled but could not find any suitable answer.
