Trouble with using ToggleButton

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?

Answer 1

Thats because you are not saving the state of ToggleButton. Use SharedPreference to save the state of ToggleButton on Button click.

Answer 2

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();
 }
 });
