LineBackgroundSpan.Standard


public static class LineBackgroundSpan.Standard
extends Object implements 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);
 
Text with LineBackgroundSpan

Summary

Inherited constants

int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Public constructors

Standard(Parcel src)

Creates a LineBackgroundSpan.Standard from a parcel

Standard(int color)

Constructor taking a color integer.

Public methods

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

abstract 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.

abstract void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Public constructors

Standard

Added in API level 29
public Standard (Parcel src)

Creates a LineBackgroundSpan.Standard from a parcel

Parameters
src Parcel: This value cannot be null.

Standard

Added in API level 29
public Standard (int color)

Constructor taking a color integer.

Parameters
color int: Color integer that defines the background color.

Public methods

describeContents

Added in API level 29
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

Added in API level 29
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.

Parameters
canvas Canvas: This value cannot be null.

paint Paint: This value cannot be null.

left int: The units of this value are pixels.

right int: The units of this value are pixels.

top int: The units of this value are pixels.

baseline int: The units of this value are pixels.

bottom int: The units of this value are pixels.

text CharSequence: This value cannot be null.

start int: start character index of the line

end int: end character index of the line

lineNumber int: line number in the current text layout

getColor

Added in API level 29
public final int getColor ()

Returns
int the color of this span.

getSpanTypeId

Added in API level 29
public int getSpanTypeId ()

Return a special type identifier for this span class.

Returns
int

writeToParcel

Added in API level 29
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: This value cannot be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
