Question

I am using a toggle button in my applications settings page. The problem is, that once I turn the toggle button on and exit from the settings page and then again go to settings, it shows that toggle button is in off state. I want it in the on state until the user turns it off, even if the app is closed… Is it possible?

You should use SharedPreferences for that with an onCheckedChangedListener.

Here’s an example how I’m handling it for a CheckBox (should be equal to a ToggleButton, so it’s untested, but should work!):

    ToggleButton mToggleButton = (ToggleButton) findViewById(R.id.mToggleButton);
    mToggleButton.setChecked(getSharedPreferences(mSharedPreferences, MODE_PRIVATE).getBoolean("dontShowAgain", false));
    mToggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            SharedPreferences settings = getSharedPreferences(mSharedPreferences, MODE_PRIVATE);
            SharedPreferences.Editor editor = settings.edit();
            editor.putBoolean("dontShowAgain", isChecked);
            editor.commit();
        }
    });
