class
LineBackgroundSpan.Standard
extends Object
implements
LineBackgroundSpan,
ParcelableSpan
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);
Text with LineBackgroundSpan

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 |
drawBackground
public void drawBackground (Canvas canvas,
Paint paint,
int left,
int right,
int top,
int baseline,
int bottom,
CharSequence text,
int start,
int end,
int lineNumber)
Draw the background on the canvas.
