Just remove the line toggle toggle    from your click listener toggle   method will always reset your toggle button value    And as you are trying to take the value of EditText in string variable which always remains same as you are getting value in onCreate   so better directly use the EditText to get the value of it in your onClick listener   Just change your code as below its working fine now     btn setOnClickListener new OnClickListener               Override         public void onClick View v                   TODO Auto-generated method stub                          toggle toggle                if   ed getText   toString   equalsIgnoreCase  1                       toggle setTextOff  TOGGLE ON                    toggle setChecked true                 else if   ed getText   toString   equalsIgnoreCase  0                       toggle setTextOn  TOGGLE OFF                    toggle setChecked false

I think what are attempting is semantically same as a radio button when 1 is when one of the options is selected and 0 is the other option   I suggest using the radio button provided by Android by default   Here is how to use it- http   www mkyong com android android-radio-buttons-example   and the android documentation is here-  http   developer android com guide topics ui controls radiobutton html  Thanks
