int heightMeasureSpec)
View
Measure the view and its content to determine the measured width and the
measured height. This method is invoked by View.measure(int, int) and
should be overriden by subclasses to provide accurate and efficient
measurement of their contents.
CONTRACT: When overriding this method, you
must call View.setMeasuredDimension(int, int) to store the
measured width and height of this view. Failure to do so will trigger an
IllegalStateException, thrown by
View.measure(int, int). Calling the superclass'
View.onMeasure(int, int) is a valid use.
The base class implementation of measure defaults to the background size,
unless a larger size is allowed by the MeasureSpec. Subclasses should
override View.onMeasure(int, int) to provide better measurements of
their content.
If this method is overridden, it is the subclass's responsibility to make
sure the measured height and width are at least the view's minimum height
and width (View.getSuggestedMinimumHeight() and
View.getSuggestedMinimumWidth()).
onMeasure in class ProgressBarwidthMeasureSpec - horizontal space requirements as imposed by the parent.
The requirements are encoded with
View.MeasureSpec.heightMeasureSpec - vertical space requirements as imposed by the parent.
The requirements are encoded with
View.MeasureSpec.View.getMeasuredWidth(),

View.setMeasuredDimension(int, int),
View.getSuggestedMinimumHeight(),
View.getSuggestedMinimumWidth(),
View.MeasureSpec.getMode(int),

ViewonTouchEvent in class Viewevent - The motion event.public boolean onKeyDown(int keyCode,
KeyEvent event)
ViewKeyEvent.Callback.onKeyDown(): perform press of the view
when KeyEvent.KEYCODE_DPAD_CENTER or KeyEvent.KEYCODE_ENTER
is released, if the view is enabled and clickable.
Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.
onKeyDown in interface KeyEvent.CallbackonKeyDown in class ViewkeyCode - A key code that represents the button pressed, from
KeyEvent.event - The KeyEvent object that defines the button action.public void onInitializeAccessibilityEvent(AccessibilityEvent event)
ViewAccessibilityEvent with information about
this View which is the event source. In other words, the source of
an accessibility event is the view whose state change triggered firing
the event.
Example: Setting the password property of an event in addition to properties set by the super implementation:
public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
super.onInitializeAccessibilityEvent(event);
event.setPassword(true);
}
If an View.AccessibilityDelegate has been specified via calling
View.setAccessibilityDelegate(AccessibilityDelegate) its
View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent)
is responsible for handling this call.
Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.
onInitializeAccessibilityEvent in class ProgressBarevent - The event to initialize.View.sendAccessibilityEvent(int),
View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)
ViewAccessibilityNodeInfo with information about this view.
The base implementation sets:
AccessibilityNodeInfo.setParent(View),AccessibilityNodeInfo.setBoundsInParent(Rect),AccessibilityNodeInfo.setBoundsInScreen(Rect),AccessibilityNodeInfo.setPackageName(CharSequence),AccessibilityNodeInfo.setClassName(CharSequence),AccessibilityNodeInfo.setContentDescription(CharSequence),AccessibilityNodeInfo.setEnabled(boolean),AccessibilityNodeInfo.setClickable(boolean),AccessibilityNodeInfo.setFocusable(boolean),AccessibilityNodeInfo.setFocused(boolean),AccessibilityNodeInfo.setLongClickable(boolean),AccessibilityNodeInfo.setSelected(boolean),Subclasses should override this method, call the super implementation, and set additional attributes.
If an View.AccessibilityDelegate has been specified via calling
View.setAccessibilityDelegate(AccessibilityDelegate) its
View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo)
is responsible for handling this call.
onInitializeAccessibilityNodeInfo in class ProgressBarinfo - The instance to initialize.public boolean performAccessibilityAction(int action,

ViewAccessibilityNodeInfo.
If an View.AccessibilityDelegate has been specified via calling
View.setAccessibilityDelegate(AccessibilityDelegate) its
