VerifiedMotionEvent

public final class VerifiedMotionEvent
extends VerifiedInputEvent implements Parcelable

java.lang.Object
   ↳ android.view.VerifiedInputEvent
     ↳ android.view.VerifiedMotionEvent


MotionEvent that has been verified by the system. The data contained in this class is always a subset of a MotionEvent. Use this class to check which data has been confirmed by the system to be authentic. Most applications do not need to use this class.

CREATOR

public static final Creator<VerifiedMotionEvent> CREATOR

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

equals

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getActionMasked

public int getActionMasked ()

The masked action being performed, without pointer index information.

Returns
int Value is MotionEvent.ACTION_DOWN, MotionEvent.ACTION_POINTER_DOWN, MotionEvent.ACTION_CANCEL, MotionEvent.ACTION_POINTER_UP, or MotionEvent.ACTION_UP

See also:

getButtonState

public int getButtonState ()

The state of all buttons that are pressed such as a mouse or stylus button.

Returns
int

See also:

getDownTimeNanos

public long getDownTimeNanos ()

The time that the gesture started, in nanoseconds. Uses the same time base as SystemClock.uptimeMillis()

Returns
long

See also:

getFlag

public Boolean getFlag (int flag)

Get a specific flag of this motion event, if possible. Return null if the flag value could not be checked.

Parameters
flag int: the flag of interest

Returns
Boolean Boolean(true) if the motion event has the requested flag Boolean(false) if the motion event does not have the requested flag null if the flag value could not be checked

getMetaState

public int getMetaState ()

The state of any meta / modifier keys that were in effect when the event was generated.

Returns
int

See also:

getRawX

public float getRawX ()

The raw X coordinate of the primary pointer.

Returns
float

See also:

getRawY

public float getRawY ()

The raw Y coordinate of the primary pointer.

Returns
float

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
int a hash code value for this object.

writeToParcel

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
