Is there a way to launch voice input on the softkeyboard programatically?

问题

The idea is to take a user voice input on the press of a button and pass it to the search inside the app. Because of device limitations we are using the SearchViewCompat instead of the useful SearchView. I have been able to grab the voice output using this link, but there is not a simple way to pass the text to the search bar this way.
The search view itself shows as a view (so no setText()), but if I can just say "use mic key on keyboard" or something as soon as the searchbar comes up, I think it might work. Any help would be greatly appreciated.
Thanks, SGB.

No, it's not possible. At least, there is no simple way to launch voice input without using RecognitionListener or manually clicking the voice input button on soft keyboard.

As far as I know, this post explains how to integrate voice into an IME which actually uses this library: google-voice-typing-integration. It might inspire you a bit.

Sorry to have answered my own question but here it was: I took the whole "grab a string array from voice input" off of the link in the question, then, instead of just starting a search with onSearchRequested(), I did this:

startSearch(grabString, false, null, false);


public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(aViaBuildConfig.MIC_KEY) {
        DebugLog.e(TAG , "onDown event : " + event);
        DebugLog.e(TAG , "onDown keyCode: " + keyCode);
        if(keyCode == Constants.MIC_KEY) {
            onSearchRequested();
            Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
            try {
                startActivityForResult(voiceIntent, Constants.RESULT_SPEECH);
            } catch (ActivityNotFoundException ex) {
                DebugLog.e(TAG, "Not found excpetion onKeyDown: " + ex);
            }
        }
        return super.onKeyDown(keyCode, event);
    }
    return false; 
}


protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case Constants.RESULT_SPEECH:
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == RESULT_OK && null != data) {
                 ArrayList<String> spokenSearch = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                 DebugLog.e("Glenn: " , "Speech = " + spokenSearch);
                 String grabString = spokenSearch.get(0);
                 startSearch(grabString, false, null, false);
            }
            break;
    }
}
