Show EditText B when EditText A has letters
All- I am trying to hide EditText B,C until EditText A has at least one character in it. I have tried using a textwatcher...

    EditText editText = (EditText) findViewById(R.id.p1); //A
        final EditText editText$ = (EditText) findViewById(R.id.p1$); //B
        final TextView $ = (TextView) findViewById(R.id.$); //C
        
        editText$.setVisibility(View.INVISIBLE);
        $.setVisibility(View.INVISIBLE);
        
        
        editText.addTextChangedListener(new TextWatcher(){
        	
            public void afterTextChanged(Editable arg0) {
            }
            public void beforeTextChanged(CharSequence s, int start,
                    int count, int after) {
            	}
            public void onTextChanged(CharSequence s, int start,
                    int before, int count) {
            	
            	if (s.toString() != "" ) {            		
                	editText$.setVisibility(View.VISIBLE);
                	$.setVisibility(View.VISIBLE);
                }
                else {
                	editText$.setVisibility(View.INVISIBLE);
                	$.setVisibility(View.INVISIBLE);        	
                }
            }
        });

but EditText B (and C) are either always visible or never visible depending on weather or not I declare `editText$.setVisibility(View.INVISIBLE);
    $.setVisibility(View.INVISIBLE);` before the TextWatcher. Can someone tell me what I am doing wrong? Thank you for your time!
