Android RecognizerIntent Speech recognition

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

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.
