EditText android studio

Question

I create an application on android studio,I have 4 EditText to write an IP Address, I want to move automaticly the cursor to the following EditText when I write 3 numbers in an EditText. How to do Thanks You?

Answer 1

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"

2. 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"

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
