我有一个MainActivity类,在这里我想听听从非活动类调用的textToSpeech。 no活动类是自动调用的,因此为了能够通过构造函数发送上下文,我不对其进行调用。
这是没有活动的课程
public class SetTiredAction implements Action
{
private TextToSpeech textToSpeech;
@Override
public void execute(State state)
{
MenuActivity activity = new MenuActivity();
Log.i("TEIRE", "TIRED");
textToSpeech = new TextToSpeech(activity.getContext(), new TextToSpeech.OnInitListener()
{
@Override
public void onInit(int status)
{
if (status == TextToSpeech.SUCCESS)
{
int ttsLang = textToSpeech.setLanguage(Locale.US);
Log.i("TTS", "Initialization success.");
}
}
});
textToSpeech.speak("Are you tired?", TextToSpeech.QUEUE_FLUSH, null, null);
textToSpeech.shutdown();
}
}
在MenuActivity类中,我有一个获取上下文的方法,但是却收到了错误调用目标异常。
我该如何解决这个问题?
