Question

我构建了一个帮助类，其中包含了一些我需要的文本到语音合成方法，但是我无法在没有getApplicationContext（）的情况下启动TextToSpeech对象。我该如何发起？

public class SpeechHelper {
    private TextToSpeech speech;
    private Context context = null;

    public SpeechHelper(Context context)
    {
        this.context = context;
        speech = new TextToSpeech(getApplicationContext(), context);
    }

这是您实现接口的代码：

public class SpeechHelper implements OnInitListener {
    private TextToSpeech speech;
    private Context context = null;

    public SpeechHelper(Context context)
    {
        this.context = context;
        speech = new TextToSpeech(context, this);
    }

    @Override
    public void onInit(int status) {
        // TextToSpeech engine is initialized
    }
}

从非Activity类启动TextToSpeech？
