How to write SpannableString to parcel?

Question

In my application I have dialog which consists few SpannableString objects. Because this is dialog, I need to be able to store it when user leaves application and comes back to it later on.

But the problem is how can I write SpannableString into Parcel?

Answer 1

I actually found out some way to do it using already existing functions, although I am not sure if it works for all type of spans, or just for those that I am using.

Inside write parcel methos you have to add

@Override
public void writeToParcel(Parcel dest, int flags) {
    TextUtils.writeToParcel(mSpannableString, dest, flags);
}

and next in order to extract SpannableString out of Parcel you should use this

public CustomConstructor(Parcel parcel) {
    mSpannableString = (SpannableString) TextUtils.CHAR_SEQUENCE_CREATOR.createFromParcel(parcel);
}

Answer 2

Use TextUtils.writeToParcel() method

Supporting spans in TextUtils

TextUtils line 555-604 public static final int ALIGMENT_SPAN = 1; ......
