Dynamically Changing the Text between EditTexts

Question

I have two edittext fields in a layout. When i type something in edittext1, the same text should get filled up in edittext2 dynamically and vice versa. How can i do that??

Give a look to this http://developer.android.com/reference/android/text/TextWatcher.html — Jeremy D, Oct 14 '13 at 07:33

You add TextWatcher to both the Edittext as follows

    EditText myTextBox = (EditText) findViewById(R.id.myTextBox);
EditText myOutputBox = (EditText) findViewById(R.id.myOutputBox);
      myTextBox.addTextChangedListener(new TextWatcher() {

       public void afterTextChanged(Editable s) {
       }

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

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

Similarly for other Edittext.

 myOutputBox.addTextChangedListener(new TextWatcher() {

           public void afterTextChanged(Editable s) {
           }

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

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

Take a look at EditText#addTextChangedListener. All you need to do is update the desired EditText inside afterTextChanged method.
