How to catch event when EditText is filled and new key is pressed?


<EditText
    android:id="@+id/name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:imeOptions="actionNext"
    android:inputType="textNoSuggestions|textCapCharacters"
    android:maxLength="3"
    android:hint="ABC"
    />

Also have another EditText that should be focused when all 3 symbols are filled in the name.

name.addTextChangedListener(object: TextWatcher {
    override fun afterTextChanged(s: Editable?) {
        // Move to surname when all three symbols are entered.
        if (name.text.toString().length == 3) {
            surname.requestFocus()
        }
    }

    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) { }

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) { }
})

It works right when we enter 1, 2 and 3 symbols. But when we select last position in name, press a new letter in a keyboard, nothing happens. I tried to catch a key press with

name.setOnKeyListener { v, keyCode, event ->
    if (name.text.getText().length == 3) {
        surname.requestFocus()
    }
    false
}

but an event doesn't arise. How to move focus?


Solution

  • Change maxLength to 4

    android:maxLength="4"

    In afterTextChanged :

     override fun afterTextChanged(s: Editable?) {
        // Move to surname when all three symbols are entered.
        if (name.isFocused() && name.text.toString().length > 3) {
            surname.requestFocus();
            name.setText(s.toString().substring(0,3));
    
        }
    }
