執行個體方法

getPresetSize()

Gets the current preset size type

public final int getPresetSize()

Returns

The current preset size type, if set; CUSTOM if not

setPresetSize(int)

Apply a preset size to this profile photo

public final void setPresetSize(int sizeType)

參數	說明
`sizeType`	The size type to apply: SMALL, NORMAL or LARGE

isCropped()

Indicates whether the cropped version of the profile photo has been chosen

public final boolean isCropped()

Returns

True if the cropped version is chosen, false if not.

setCropped(boolean)

Sets the profile photo to be the cropped version, or the original version

public final void setCropped(boolean showCroppedVersion)

參數	說明
`showCroppedVersion`	True to select the cropped version False to select the standard version

getProfileId()

Returns the profile Id for the current profile photo

public final String getProfileId()

Returns

The profile Id

setProfileId(String)

Sets the profile Id for this profile photo

public final void setProfileId(String profileId)

參數	說明
`profileId`	The profileId NULL/Empty String will show the blank profile photo

getOnErrorListener()

Returns the current OnErrorListener for this instance of ProfilePictureView

public final OnErrorListener getOnErrorListener()

Returns

The OnErrorListener

setOnErrorListener(OnErrorListener)

Sets an OnErrorListener for this instance of ProfilePictureView to call into when certain exceptions occur.

public final void setOnErrorListener(OnErrorListener onErrorListener)

參數	說明
`onErrorListener`	The Listener object to set

setDefaultProfilePicture(Bitmap)

The ProfilePictureView will display the provided image while the specified profile is being loaded, or if the specified profile is not available.

public final void setDefaultProfilePicture(Bitmap inputBitmap)

參數	說明
`inputBitmap`	The bitmap to render until the actual profile is loaded.

onMeasure(int, int)

Overriding onMeasure to handle the case where WRAP_CONTENT might be specified in the layout. Since we don't know the dimensions of the profile photo, we need to handle this case specifically.

The approach is to default to a NORMAL sized amount of space in the case that a preset size is not specified. This logic is applied to both width and height

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)

參數	說明
`widthMeasureSpec`
`heightMeasureSpec`

onLayout(boolean, int, int, int, int)

In addition to calling super.Layout(), we also attempt to get a new image that is properly size for the layout dimensions

protected void onLayout(boolean changed, int left, int top, int right, int bottom)

參數	說明
`changed`
`left`
`top`
`right`
`bottom`

onSaveInstanceState()

Some of the current state is returned as a Bundle to allow quick restoration of the ProfilePictureView object in scenarios like orientation changes.

protected Parcelable onSaveInstanceState()

Returns

A Parcelable containing the current state

onRestoreInstanceState(Parcelable)

If the passed in state is a Bundle, an attempt is made to restore from it.

protected void onRestoreInstanceState(Parcelable state)

參數	說明
`state`	A Parcelable containing the current state

onDetachedFromWindow()

protected void onDetachedFromWindow()

常數

SMALL

Indicates that the profile image should fit in a SMALL X SMALL space, regardless of whether the cropped or un-cropped version is chosen. Used in calls to setPresetSize() and getPresetSize(). Corresponds with the preset_size Xml attribute that can be set on ProfilePictureView.

public static final int SMALL

NORMAL
