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.

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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
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 inequals
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
method, then calling thehashCode
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
method, then calling thehashCode
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.
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 |
