回答1:

On reachin the count you change the focus of the edittext to the next one

Edittext edt1;
Edittext edt2:
//mount the views to java from xml
edt1.addTextChangedListener(this);  
@Override
public void afterTextChanged(Editable s) {
    // TODO Auto-generated method stub

}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
        int after) {
    // TODO Auto-generated method stub


}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
    // TODO Auto-generated method stub
if(count==length){
edt2.requestFocus()
}
}

This approach works by inspecting the length of inputted text after the text field changes.

EditText textBox1;
EditText textBox2;

textBox1.addTextChangedListener(this);

@Override
public void afterTextChanged(Editable s) {
   if (s.length() == MAX_LENGTH) {
      textBox2.requestFocus();
   }
}

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

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