SharedPreferences in a edittext of a AlertDialog

I'm using TextToSpeech for the first time and i have a problem.. I created a dialog with a editText where i can write something:

AlertDialog.Builder alert = new AlertDialog.Builder(this);

alert.setTitle("Title");
alert.setMessage("Message");

// Set an EditText view to get user input 
final EditText input = new EditText(this);
alert.setView(input);

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
  value = input.getText().toString();
  // Do something with value!
  }
});

alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int whichButton) {
    // Canceled.
  }
});

alert.show();

I need save in preferences that value.

I created this one:

private void prefvalue(String tag) {
  String name = savename.getString(Tag, null);
  SharedPreferences.Editor preferencesEditor = savename.edit();
  preferencesEditor.putString("tag", tag);
  preferencesEditor.commit();
}

well.. now in onCreate what have i to do? Because i tried do something like

input.setText(savename.getString("tag", Default Value"));

where input is the editText inside the AlertDialog. But of course doesn't work because it doesn't find the input variable.

you can save that value on Click of positive button.

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
value = input.getText().toString();

 SharedPreferences sp = getSharedPreference("MyKey",0);
 SharedPreferences.Editor preferencesEditor = sp.edit();
 preferencesEditor.putString("tag", value);
 preferencesEditor.commit();

}
});

Now retrieve anywhere where you want.

SharedPreferences sp = getSharedPreference("MyKey",0);
String data = sp.getString("tag","");

Now set this data string to your EditText.
