How To Change Text Background Color In Android Studio

BackgroundColorSpan

public class BackgroundColorSpan
extends CharacterStyle implements UpdateAppearance, ParcelableSpan

Changes the groundwork colour of the text to which the span is attached.

For example, to set a light-green groundwork color for a text you would create a SpannableString based on the text and set the bridge.

          SpannableString string = new SpannableString("Text with a groundwork color span"); string.setSpan(new BackgroundColorSpan(color), 12, 28, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Set a background color for the text.

Summary

Inherited constants

From interface android.bone.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor flake used with `describeContents()`: indicates that the Parcelable object'southward flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object existence written is a return value, that is the event of a part such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Public constructors
`BackgroundColorSpan(int color)` Creates a `BackgroundColorSpan` from a color integer.
`BackgroundColorSpan(Bundle src)` Creates a `BackgroundColorSpan` from a parcel.

Public methods
`int`	`describeContents()` Draw the kinds of special objects contained in this Parcelable instance'due south marshaled representation.
`int`	`getBackgroundColor()`
`int`	`getSpanTypeId()` Return a special type identifier for this bridge class.
`void`	`updateDrawState(TextPaint textPaint)` Updates the background color of the TextPaint.
`void`	`writeToParcel(Bundle dest, int flags)` Flatten this object in to a Parcel.

Inherited methods

From class android.text.style.CharacterStyle

`CharacterStyle`	`getUnderlying()` Returns "this" for most CharacterStyles, just for CharacterStyles that were generated by `wrap(CharacterStyle)`, returns the underlying CharacterStyle.
`abstract void`	`updateDrawState(TextPaint tp)`
`static CharacterStyle`	`wrap(CharacterStyle cs)` A given CharacterStyle tin but practical to a unmarried region of a given Spanned.

From course java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage drove determines that there are no more than references to the object.
`last Grade<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash lawmaking value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object'southward monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`look(long timeout, int nanos)` Causes the current thread to await until some other thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the electric current thread, or a certain amount of existent time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to expect until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`look()` Causes the current thread to look until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

From interface android.text.ParcelableSpan

abstract int

getSpanTypeId()

Render a special type identifier for this span course.

From interface android.bone.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects independent in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Bundle.

Public constructors

BackgroundColorSpan

public BackgroundColorSpan (int color)

Creates a BackgroundColorSpan from a color integer.

Parameters
`color`	`int`: color integer that defines the background color

BackgroundColorSpan

public BackgroundColorSpan (Parcel src)

Creates a BackgroundColorSpan from a package.

Parameters
`src`	`Bundle`: This value cannot be `nix`.

Public methods

describeContents

public int describeContents ()

Describe the kinds of special objects independent 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 case. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getBackgroundColor

public int getBackgroundColor ()

Returns
`int`	the background color of this bridge.

getSpanTypeId

public int getSpanTypeId ()

Return a special type identifier for this span class.

Returns
`int`

updateDrawState

public void updateDrawState (TextPaint textPaint)

Updates the background color of the TextPaint.

Parameters
`textPaint`	`TextPaint`: This value cannot exist `null`.
