I have an editText (R.id.editText1). But when i exit the activity and restart it, the text is gone. So i thought that i make an option menu.

I have an editText (R.id.editText1). But when i exit the activity and restart it, the text is gone. So i thought that i make an option menu.

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(0, MENU_SAVE, 开发者_高级运维0, "Save");
    menu.add(1, MENU_GET, 1, "Get");
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case MENU_SAVE:
        Here i must save the editText1
        return true;
    case MENU_GET:
        Here i must get the editText1 that i have saved
        return true;
    }

    return false;

But i don't now how to save an editText and how to load it. I hope you can help me, because i'm newbe to android.

Try using a SharedPrefrences to save the value in an edittext.


Depends on how long you want to persist the data and how big the text is. Checkout this page on Android.com

SharedPrefrences is an easy way to do this.
