Take a look at below code, it may help you :

EditText etSearch = (EditText) view.findViewById(R.id.etSearch);

etSearch.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                String str = etSearch.getText().toString();
                if (str.isEmpty()) {
                    btnClear.setVisibility(View.INVISIBLE);
                } else {
                    btnClear.setVisibility(View.VISIBLE);
                }
            }

            @Override

Text-watcher may work for you

If(editText1.getText.toString.length>0)
 {
  if(button1.getVisibility == View.GONE)
  {
  button1.setVisibility(View.VISIBLE)
  }
}
else
{
 if(button1.getVisibility == View.VISIBLE)
  {
  button1.setVisibility(View.GONE)
  }
}

  button1.setVisibility(View.VISIBLE)
   }
}
else

Try this code

Field1.addTextChangedListener(new TextWatcher() {

     @Override
      public void afterTextChanged(Editable s) {}

     @Override    
       public void beforeTextChanged(CharSequence s, int start,
       int count, int after) {
      }

    @Override    
    public void onTextChanged(CharSequence s, int start,
       int before, int count) {
       if(s.length() != 0)
        // set the visibility
    }
     });

You can use a TextWatcher, a type of Listener:

yourEditText.addTextChangedListener(new TextWatcher() {

      public void afterTextChanged(Editable s) {

        //Here, you can check for text size...
        int length = editText.toString().length();
         [...]



      }

      public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

      public void onTextChanged(CharSequence s, int start, int before, int count) {}
   });
}

}
