The profile Id
setProfileId(String)

Sets the profile Id for this profile photo

public final void setProfileId(String profileId)

getOnErrorListener()

Returns the current OnErrorListener for this instance of ProfilePictureView

public final OnErrorListener getOnErrorListener()

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

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
inputBitmapThe 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
stateA Parcelable containing the current state
