Question

Problem is that, when screen changes orientation, textview background color is gone.
here is TextView definition:

<TextView
    android:id="@+id/nomResult"
    android:layout_width="fill_parent"
    android:layout_height="80sp"
    android:text="Nom result"
    android:layout_below="@id/svitrkods"
    android:layout_alignRight="@+id/svitrkods" 
    android:layout_above="@+id/exit_button"
    android:freezesText="true"
    />

App is inventory app. When product is already in inventory, then i am displaying text in textview with red background. vaiIrInvent.setBackgroundColor(0xfff00000); that works. but when screen rotates, background color is gone…
When application stars, i save original background color of textview defBackColor = vaiIrInvent.getBackground();
then in app i am switching to red or default.

if (isInInventory)
{
    vaiIrInvent.setBackgroundColor(0xfff00000);
}
else
{
    vaiIrInvent.setBackgroundDrawable(defBackColor);
}

Maybe there is some option like android:freezesText ?
Thanks.

Answer to my situation is:
save scanned barcode when screen orientation changes

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
  // Save entered code 
  savedInstanceState.putString("svkKods", svkKods.getText().toString());
  super.onSaveInstanceState(savedInstanceState);
}

and restore code and query db.

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
  super.onRestoreInstanceState(savedInstanceState);
  // Restore UI state from the savedInstanceState.
  // This bundle has also been passed to onCreate.
  String mystr = savedInstanceState.getString("svkKods");
  svkKods.setText(mystr);
  //if code presents 
  if (mystr.length() > 3) FindKods(mystr); //query database and fill all texts and variables
}

i am doing this way because in a variable is stored state, when barcode is found in database and then user can submit changes. otherwise is displayed message to must find barcode …
