Answer 1

[1] you can try below code

String yourtext=mSearchText.getText().toString().trim();
if(!TextUtils.isEmpty(yourtext)) //or else you can use  if(yourtext!=null && !yourtext.equalsIgnoreCase(""))
{
    mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
            if(actionId == EditorInfo.IME_ACTION_SEARCH
                    || actionId == EditorInfo.IME_ACTION_DONE
                    || keyEvent.getAction() == KeyEvent.ACTION_DOWN
                    || keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){

                //execute your method for searching
                geoLocate();
            }

            return false;
        }
    });
}

[2] else you can achieve your functionality using this(Direct method calling)

String yourtext=mSearchText.getText().toString().trim();
if(!TextUtils.isEmpty(yourtext)) //or else you can use  if(yourtext!=null && !yourtext.equalsIgnoreCase(""))
{
     //execute your method for searching
                geoLocate();
}
