Question

我无法让TextToSpeech工作。

在我看来，我无法通过onInit方法初始化，因为我似乎无法调试此代码。因此，我想知道如何以编程方式解雇它。

或许我的环境设置错了。我正在运行Android Studio Beta 3分钟SDK 22.

public class MyActivity extends AppCompatActivity implements TextToSpeech.OnInitListener {

    TextToSpeech tospeech;

    protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.activity_tree_play);
              tospeech = new TextToSpeech(this, this);
    }

    @Override
    public void onInit(int status) {

         if (status == TextToSpeech.SUCCESS) {

            int result = tospeech.setLanguage(Locale.UK);

            if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
               Log.e("TTS", "This Language is not supported");
             } 
             else {

                 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                     tospeech.speak("I am a dog",TextToSpeech.QUEUE_FLUSH,null,null);
                 } 
                 else 
                 {
                     tospeech.speak("I am a dog", TextToSpeech.QUEUE_FLUSH, null);
                 }
        }

    } else {
        Log.e("TTS", "Initilization Failed!");
    }

}

}

好的，上面的代码没错。我的问题是我有一个异步任务，它会在onInit触发之前运行完毕。

解决方案是将异步任务的执行调用放入onInit方法。这样，可以保证在继续之前初始化TextToSpeech变量。

TextToSpeech onInit没有开火
