How to make Toggle button programmatically On & OFF in Android?

To change both the state and the UI of a toggle button you need to implement two functions:

toggle.setChecked(Boolean value)
toggle.setSelected(Boolean value)

setChecked() sets the intrinsic boolean associated with the view object and setSelected sets the UI.

To Toggle set and get value use the following

togg=toggleButton.getText().toString();
    // Get the default value off 
     String off =mo.getOn();
    if (off.equals("OFF")){
    holder.toggleButton.setChecked(false);
    }else{
    holder.toggleButton.setChecked(true);
    }
