Saving and restoring view state android [duplicate]

Question

I'm aware of activity state saving and restoring. But what I want to do is saving and restoring the state of a view. I have a custom view and two overrided methods in it:

@Override
protected void onRestoreInstanceState(Parcelable state) {
    if (state instanceof Bundle) {
        Bundle bundle = (Bundle) state;
        currentLeftX = bundle.getInt(CURRENT_LEFT_X_PARAM, 0);
        currentTopY = bundle.getInt(CURRENT_TOP_Y_PARAM, 0);
    }
    super.onRestoreInstanceState(state);
}

@Override
protected Parcelable onSaveInstanceState() {
    super.onSaveInstanceState();
    Bundle bundle = new Bundle();
    bundle.putInt(CURRENT_LEFT_X_PARAM, currentLeftX);
    bundle.putInt(CURRENT_TOP_Y_PARAM, currentTopY);
    return bundle;
}

I expected this to work seamless, but encountered and error:

Caused by: java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.os.Bundle instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/mapViewId. Make sure other views do not use the same id. at android.view.View.onRestoreInstanceState(View.java:6161)

But this view is the only one in my activity. So, I'm asking:

What is the right way to save the state of the view?

Answer 1

You drop the result of super.OnSaveInstanceState() and return your own. Then later at OnRestoreInstanceState(Parcelable) you return the one which you created.
