title: How do I add TextWatchers to multiple EditTexts
body: <p>I have looked at some other questions and posts, but I can't seem to figure this out... I am building a conversion app, I am able to auto populate Feet and Yards by putting the inches in, using addTextChangedListener, but I cant figure out how to addTextChangedListener to the other fields so that I can enter Feet and automatically convert to Inches and Yards, and Yards to Inches and Feet... </p>
  
  <pre><code>   @Override
  protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
  
         final EditText editIn = (EditText) findViewById(R.id.editIn);
         final EditText editFt = (EditText) findViewById(R.id.editFt);
         final EditText editYd = (EditText) findViewById(R.id.editYd);
  
         editIn.addTextChangedListener(new TextWatcher() {
             @Override
             public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) { }
             @Override
             public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {
                 try {
                     double in = Double.valueOf(editIn.getText().toString());
                     double ft = in / 12;
                     double yd = in / 36;
                     editFt.setText(String.valueOf(ft));
                     editYd.setText(String.valueOf(yd));
                 } catch (NumberFormatException e) {
                     e.printStackTrace();
                 }
             }
             @Override
             public void afterTextChanged(Editable editable) { }
