Android RecognizerIntent Speech recognition

Question

How to handle the visibility of an image(ImageView) in the event the RecognizerIntent finishes due to the user not speaking

if (RecognizerIntent.EXTRA_RESULTS == null){
image1.setVisibility(View.VISIBLE);///microphone icon
}

or

if (RecognizerIntent.ACTION_RECOGNIZE_SPEECH == null){
image1.setVisibility(View.INVISIBLE);///microphone
}

thnx

Answer 1

In the code above you are just testing if the constants are null, which they are not. You have to start the recognition somewhere in the code by

    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    //... put other settings in the Intent 
    startActivityForResult(intent, REQUEST_CODE);

and receive the result in

     @Override
     protected void onActivityResult(int requestCode, int resultCode, Intent data)
     {
       if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
         ArrayList<String> results = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);
          //... do your stuf with results
         }
     super.onActivityResult(requestCode, resultCode, data);
     }

A more customizable way is to use SpeechRecognizer directly. See for example this question.
