问题描述
在我的应用我识别用户说退出或关闭和应用程序应该关闭。有了这个code
In my app I recognize the user saying "exit" or "close" and the app should close.With this code
SpeechRecognizer sr;
Map<String, Integer> dictionary;
private static final int EXIT = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
populateDictionary();
SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer(this);
sr.setRecognitionListener(this);
Intent voiceIntent = RecognizerIntent.getVoiceDetailsIntent(getApplicationContext());
sr.startListening(voiceIntent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private void populateDictionary() {
dictionary = new HashMap<String, Integer>();
dictionary.put("exit", EXIT);
dictionary.put("close", EXIT);
}
@Override
public void onResults(Bundle results) {
ArrayList<String> strList = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for (int i = 0; i < strList.size();i++ ) {
String sentence = strList.get(i).toLowerCase(Locale.getDefault());
Integer operation = dictionary.get(sentence);
if(operation != null){
switch(operation){
case EXIT:{
this.finish();
};break;
}
}
}
}
我得到这个运行时错误，语音识别后。
I get this runtime error, after the speech recognition.

如果我试图摧毁SpeechRecognizer我得到另一个运行时错误，因为 SR 为空。
If I try to destroy the SpeechRecognizer I get another runtime error because sr is null.
@Override
public void onDestroy(){
sr.destroy();
super.onDestroy();
}

我应该怎么办？
What should I do?
推荐答案
这个问题是最微不足道的曾经：我声明了 SpeechRecognizer 两次，一个是类另一个的onCreate（）方法内。变量初始化只是在功能范围，所以外的函数 SR 总是空。
The problem was the most trivial ever: I declared the SpeechRecognizer two times, one for the class and another inside the onCreate() method. The variable was initialized only in the function scope, so outside the function sr was always null.
