How to save the state of the toogleButton on/off selection?

Question

Hello i have implemented the application based on the toggleButton selection. but while i close that application and then reopen it, it will get in to its default selection

Answer 1

Use SharedPreferences like erdomester suggested, but I modified little bit his code. There's some unneeded conditions.

tg = (ToggleButton) findViewById(R.id.toggleButton1);

tg.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(View v)
    {
       SharedPreferences.Editor editor = preferences.edit();
       editor.putBoolean("tgpref", tg.isChecked()); // value to store
       editor.commit();
    }
});

And this is how to retrieve the values:

SharedPreferences preferences = getPreferences(MODE_PRIVATE);
boolean tgpref = preferences.getBoolean("tgpref", true);  //default is true

tg.setChecked(tgpref);
