如何在android中使用google语音识别器识别单词

Logcat

我的应用程序会识别一个词，例如mobile，然后它会做一些事情。我发现使用

谷歌语音识别器

很简单。如下图所示：

public abstract class SpeechRecognizerResult extends Activity implements SpeechRecognizerManager.OnResultListener {
private final String TAG = getClass().getSimpleName();
private SpeechRecognizerManager mSpeechRecognizerManager;
private TextView txt_result;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recognizer_listener);

    mSpeechRecognizerManager =new SpeechRecognizerManager(this);
    mSpeechRecognizerManager.setOnResultListner(this);

    txt_result= (TextView) findViewById(R.id.text_result);
}

@Override
public void OnResult(ArrayList<String> commands) {

    for(String command:commands) {
        if (command.equals("mobile")){
            Toast.makeText(this, "You said:" + command, Toast.LENGTH_SHORT).show();
            txt_result.setText(command);
            return;
        }

    }
}
}

公共抽象类SpeechRecognizerResult扩展活动实现SpeechRecognizerManager.OnResultListener{
私有最终字符串标记=getClass（）.getSimpleName（）；
私人演讲识别经理mSpeechRecognizerManager；
私有文本视图txt_结果；

mSpeechRecognizerManager=新的SpeechRecognizerManager（此）；
mSpeechRecognizerManager.setOnResultListner（此文件）；
txt_result=（TextView）findViewById（R.id.text_result）；
}
@凌驾
public void OnResult（ArrayList命令）{
用于（字符串命令：命令）{
if（command.equals（“移动”））{
Toast.makeText（这个，“你说：”+命令，Toast.LENGTH_SHORT.show（）；
txt_result.setText（命令）；
返回；
}
}
}
}

及

• 我应该如何解决问题
• 我如何继续识别（找到第一个后）

将您的SpeechRecognitzerResult类公开，而不是抽象的。@brandall。噢！非常感谢。但现在我说mobile时什么也没发生。为什么？您在哪里调用

startListening（）

？我在您的代码中看不到它。@brandall。我希望在设备锁定时看到它（尽管应用程序在后台运行），那么我应该把它放在哪里？一个锁屏小部件
