Question

我正在测试我的可访问性应用程序。如果用户在中间关闭可访问性，则应用程序崩溃，原因是服务未注册：android.speech.tts.TextToSpeech。我在onDetachedFromWindow方法中调用了setJavaScriptEnabled（false），但是没有用。仍有错误。

我没有在webview中使用应用程序上下文，因为webview正在使用xml进行初始化。

Answer 1

最后它已经解决了。我必须从xml文件移动所有webview并动态添加它们并传递应用程序上下文。

WebView webView = new WebView(getApplicationContext());

服务未注册：android.speech.tts.TextToSpeech
