构造器详细资料

StandardScaleGestureDetector

public StandardScaleGestureDetector(android.content.Context context,
                                    PalmapGesturesManager palmapGesturesManager)

方法详细资料

analyzeEvent

protected boolean analyzeEvent(android.view.MotionEvent motionEvent)

覆盖:

analyzeEvent 在类中 ProgressiveGesture<StandardScaleGestureDetector.StandardOnScaleGestureListener>

gestureStopped

protected void gestureStopped()

覆盖:

gestureStopped 在类中 ProgressiveGesture<StandardScaleGestureDetector.StandardOnScaleGestureListener>

interrupt

public void interrupt()

从类复制的说明: ProgressiveGesture

Interrupt a gesture by stopping it's execution immediately. Forces gesture detector to meet start conditions again in order to resume.

覆盖:

interrupt 在类中 ProgressiveGesture<StandardScaleGestureDetector.StandardOnScaleGestureListener>

provideHandledTypes

@NonNull
protected java.util.Set<java.lang.Integer> provideHandledTypes()

指定者:

provideHandledTypes 在类中 ProgressiveGesture<StandardScaleGestureDetector.StandardOnScaleGestureListener>

isScalingOut

public boolean isScalingOut()

Check whether user is scaling out.

返回:

true if user is scaling out, false if user is scaling in

getUnderlyingScaleGestureDetector

public android.view.ScaleGestureDetector getUnderlyingScaleGestureDetector()

Get the underlying ScaleGestureDetector.

返回:

underlying ScaleGestureDetector

getSpanSinceStartThreshold

public float getSpanSinceStartThreshold()

Get the threshold span in pixels between initial fingers position and current needed for this detector to qualify it as a scale gesture.

返回:

span threshold

setSpanSinceStartThreshold

public void setSpanSinceStartThreshold(float spanSinceStartThreshold)

Set the threshold span in pixels between initial fingers position and current needed for this detector to qualify it as a scale gesture.

We encourage to set those values from dimens to accommodate for various screen sizes.

参数:

spanSinceStartThreshold - delta span threshold

setSpanSinceStartThresholdResource

public void setSpanSinceStartThresholdResource(@DimenRes
                                               int spanSinceStartThresholdDimen)

Set the threshold span in dp between initial fingers position and current needed for this detector to qualify it as a scale gesture.

参数:

spanSinceStartThresholdDimen - delta span threshold

setSpanSinceStartThresholdResource

public void setSpanSinceStartThresholdResource(java.lang.String spanSinceStartThresholdDimen)

getScaleFactor

public float getScaleFactor()

返回:

Scale factor.
