LineBackgroundSpan,
ParcelableSpan
| java.lang.Object | |
| ↳ | android.text.style.LineBackgroundSpan.Standard |
Default implementation of the LineBackgroundSpan, which changes the background
color of the lines to which the span is attached.
For example, an LineBackgroundSpan can be used like this:
String text = "This is a multiline text. LineBackgroundSpan is applied here. This is a multiline text."; SpannableString string = new SpannableString(text); string.setSpan(new LineBackgroundSpan.Standard(Color.YELLOW), 26, 61, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Public methods
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int),
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR bit.
| Returns | |
|---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
