You have to constantly check the input of each editText in 
onTextChanged method, To do this, you have to implement 
addTextChangedListener on each editText and check the charSequence if 
equal = 3.

for example

    yourFirstEditText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

     if(charSequence.toString().length() == 3) {
      //call next forcus
      yourSecondEditText.requestFocus();
           }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });

    yourSecondEditText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

     if(charSequence.toString().length() == 3) {
      //call next forcus
      yourThirdEditText.requestFocus();
           }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });

//you don't need to do that for the last editText

There are multiple ways to do this.

  1. Set the inputType and maxLength attributes in xml of each of these EditTexts.

    android:inputType="number" android:maxLength="3"

Next, define the next focus item:

android:nextFocusRight="id"

  1. Alternately you can add a textChangedListener for each of the EditText's:

    editText1.addTextChangedListener(mTextWatcher);

    private final TextWatcher mTextWatcher = new TextWatcher() {

    @Override
public void onTextChanged(CharSequence s, int start, int before,
        int count) {

}

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

}

@Override
public void afterTextChanged(Editable s) {
    if (s.length() == 3) {
        // editText2.requestFocus();
}

    };

Try this, also u need to add two attributes to the xml and each views as well: 

android:focusable="true";
android:focusableInTouchMode="true"
