can we invoke any activty or service on android wear using voice command

Question

我知道我可以通过从磨损主屏幕调用语音命令（例如Start MyApp）开始我的应用程序启动器活动，但我想用相同的机制调用其他活动，即使用语音命令，例如start B，其中B是名称我的活动除了启动器活动。我想从Wear主屏幕本身启动Activty B而不是通过我的应用程序打开。类似于应用程序启动器活动的情况可以从Wear主屏幕启动。机器人磨损支持此功能？请帮忙

Answer 1

Yes it can be done.

@Override
protected void onCreate(Bundle savedInstanceState) {
    try {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    
        voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        startActivityForResult(voiceIntent,SPEECH_RECOGNIZER_CODE);
        }

Start the activity as shown above , it'll open a default google voice listening dialogue box.

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
   try { if (requestCode == SPEECH_RECOGNIZER_CODE && resultCode == RESULT_OK) {
            List<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            String spokenText = results.get(0);
       }

Implement the above mentioned method in your activity. By matching the string "spokenText" to the Activity name you can start that activity.

你口头调用的活动会不时地改变，或者它总是第二次活动？

Well I can think of a crude fix, i assume that you have added "android:label" to your launcher activity so that the app is invoked by the voice command from the wear home screen.Add the label Value as "secondactivity"(Or the activity name you want to invoke - so that the user can use it without having to worry about the app name). Is it a problem if you finish the launcher activity in OnCreate method itself and open the second activity from there on ? Just my thoughts.
