Question

I have to implement an application in which I have set small edittext for input PIN number and Mobile Number. Each edit text contain 1 character at a time.
Now when I run this app, I found that for each box I need to give focus to each edittext.
So in this case is it possible to set focus in next edittext after character is entered in first and then goto third after character is entered in second.
so please help me out this

Here is layout image.

Answer 1

1. implements TextWatcher on EditTexts

and then when you get Edittext’s text length is 1.

2. Change focus on other EditText using

Call requestFocus() on the other EditText..

CODE: (This code is for your understanding, It may be different on your case and your need)

public class LoginActivity extends Activity implements TextWatcher
{
 .
 .
 .

  editTextUName = (EditText) findViewById(R.id.edttextusername);
  editTextUName.addTextChangedListener(this);
  editTextPwd = (EditText) findViewById(R.id.edttextpassword);
  editTextPwd.addTextChangedListener(this);

@Override
public void afterTextChanged(Editable s)
{
    if (s.toString().length() == 1)
    {
              editTextPwd.requestFocus();
    }
}
