MagnificationConfig
public final class MagnificationConfig
extends Object
implements Parcelable
java.lang.Object | |
↳ | android.accessibilityservice.MagnificationConfig |
This class describes the magnification config for AccessibilityService
to control the magnification.
When the magnification config uses MAGNIFICATION_MODE_DEFAULT
, AccessibilityService
will be able to control the activated magnifier on the display. If there is no magnifier activated, it controls the last-activated magnification mode. If there is no magnifier activated before, it controls full-screen magnifier by default.
When the magnification config uses MAGNIFICATION_MODE_FULLSCREEN
. AccessibilityService
will be able to control full-screen magnifier on the display.
When the magnification config uses MAGNIFICATION_MODE_WINDOW
and the platform supports PackageManager.FEATURE_WINDOW_MAGNIFICATION
feature. AccessibilityService
will be able to control window magnifier on the display.
If the other magnification configs, scale centerX and centerY, are not set by the Builder
, the configs should be current values or default values. And the center position ordinarily is the center of the screen.

Fields
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 |
getCenterX
public float getCenterX ()
Returns the screen-relative X coordinate of the center of the magnification viewport.
Returns | |
---|---|
float | The X coordinate |
getCenterY
public float getCenterY ()
Returns the screen-relative Y coordinate of the center of the magnification viewport.
Returns | |
---|---|
float | The Y coordinate |
getMode
public int getMode ()
Returns the magnification mode that is the current activated mode or the controlling mode of the config.
Returns | |
---|---|
int | The magnification mode |
getScale
public float getScale ()
Returns the magnification scale of the controlling magnifier
Returns | |
---|---|
float | The magnification scale |
isActivated
public boolean isActivated ()
Returns the activated state of the controlling magnifier. The controlling magnifier can be activated even if the scale returned by MagnificationConfig.getScale()
equals to 1.0.
Returns | |
---|---|
boolean | true if the magnifier is activated and showing on screen, false otherwise. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String | This value cannot be null . |
writeToParcel
public void writeToParcel (Parcel parcel, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
parcel | 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 |
