I need help with saving the state of a Checkbox.

I want to select a checkbox, then close the app and when i open the app again, i want the checkbox to still be selected.

Please can somebody help with this or at least point me in the right direction.

Your save the value in the persistent preferences when clicked. And you read its value when populating from layout

SharedPreferences settings = getSharedPreferences("preferences", 0);
final CheckBox checkBox = (CheckBox)findViewById(R.id.yourCheckBox);
checkBox.setChecked(settings.getBoolean("checkBoxValue", false));
checkBox.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
SharedPreferences settings = getSharedPreferences("preferences", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("checkBoxValue", checkBox.isChecked());
editor.commit();
}
});
