How to change the focus to next edit text in android?

Question

The User can enter only one digit in the edit text. if he enters the value in edtText1, I want the cursor automatically moves to edtText2 and so on. The user can able to edit the text which he/she has entered already. I tried the following way.

    edtPasscode1.setOnKeyListener(new OnKeyListener() {          @Override         public boolean onKey(View v, int keyCode, KeyEvent event) {             // TODO Auto-generated method stub             if (edtPasscode1.getText().length() == 1)                 edtPasscode2.requestFocus();             return false;         }     });      edtPasscode2.setOnKeyListener(new OnKeyListener() {          @Override         public boolean onKey(View v, int keyCode, KeyEvent event) {             // TODO Auto-generated method stub             if (edtPasscode2.getText().length() == 1)                 edtPasscode3.requestFocus();             return false;         }     });      edtPasscode3.setOnKeyListener(new OnKeyListener() {          @Override         public boolean onKey(View v, int keyCode, KeyEvent event) {             // TODO Auto-generated method stub             if (edtPasscode3.getText().length() == 1)                 edtPasscode4.requestFocus();             return false;         }     }); 

If the user edit the text, The cursor moves to some other editTexts and not working as desired. How can i achieve the above?

Answer 1

Try TextWatcher instead of onKeyListener

B'coz if want to edit your password, in that case TextWatcher will give you more method to dealt with..

Edited:-

StringBuilder sb=new StringBuilder();           edtPasscode1.addTextChangedListener(new TextWatcher() {              public void onTextChanged(CharSequence s, int start, int before, int count) {                  // TODO Auto-generated method stub                  if(sb.length()==0&edtPasscode1.length()==1)                  {                      sb.append(s);                      edtPasscode1.clearFocus();                      edtPasscode2.requestFocus();                      edtPasscode2.setCursorVisible(true);                   }              }               public void beforeTextChanged(CharSequence s, int start, int count,                      int after) {                   if(sb.length()==1)                  {                       sb.deleteCharAt(0);                   }               }               public void afterTextChanged(Editable s) {                  if(sb.length()==0)                  {                       edtPasscode1.requestFocus();                  }               }          }); 

Hope this work.
