android - How to use custom image for edittext password like axis bank app -

how use custom image instead of '*' in edittext password field?

see image:

any answer or hint appreciated.

the answer comes this tutorial , covers behaviour when user:

• enters login screen, keyboard open automatically.

• tries enter value in textbox background changes textbox star background.

• tries cancel/delete input value using key on keyboard textbox background change textbox without star background.

first of have create 2 drawables:

then, according approach, have implement addtextchangedlistener method on edittext. after that, parameter, create new instance of textwatcher class , implement methods:

etxtpin1.addtextchangedlistener(new textwatcher() {      @override     public void ontextchanged(charsequence s, int start, int before, int count) {        // 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 aftertextchanged(editable s) {           if(etxtpin1.gettext().tostring().trim().length()==1){            etxtpin1.clearfocus();           etxtpin2.requestfocus();           etxtpin1.setbackgroundresource(r.drawable.pin_txt_bg_star);            }        }     }); 

then, have implement setonkeylistener , method onkey:

this.etxtpin1.setonkeylistener(new view.onkeylistener() {       public boolean onkey(view paramview, int paramint, keyevent paramkeyevent) {            if ((paramkeyevent.getaction() == keyevent.action_down)&&(paramint == 67) && (loginactivity.this.etxtpin2.gettext().length() == 0)) {                etxtpin1.requestfocus();                etxtpin1.setbackgroundresource(r.drawable.pin_txt_bg);                etxtpin1.settext("");            }             return false;        }     });

another approach: create own class extends passwordtransformationmethod.

public class mypasswordtransformationmethod extends passwordtransformationmethod {     @override     public charsequence gettransformation(charsequence source, view view) {         return new passwordcharsequence(source);     }      private class passwordcharsequence implements charsequence {         private charsequence msource;         public passwordcharsequence(charsequence source) {             msource = source; // store char sequence         }         public char charat(int index) {             return '*'; // important part         }         public int length() {             return msource.length(); // return default         }         public charsequence subsequence(int start, int end) {             return msource.subsequence(start, end); // return default         }     } };
