ImageView

True when ImageView is adjusting its bounds to preserve the aspect ratio of its drawable

Return the offset of the widget's text baseline from the widget's top boundary.

Return whether this view's baseline will be considered the bottom of the view.

Returns the active color filter for this ImageView.

Return whether this ImageView crops to padding.

Return the view's drawable, or null if no drawable has been assigned.

Returns the alpha that will be applied to the drawable of this ImageView.

Return the view's optional matrix. This is applied to the view's drawable when it is drawn. If there is not matrix, this method will return null. Do not change this matrix in place. If you want a different matrix applied to the drawable, be sure to call setImageMatrix().

The maximum height of this view.

The maximum width of this view.

Return the current scale type in use by this ImageView.

Returns whether this View has content which overlaps. This function, intended to be overridden by specific View types, is an optimization when alpha is set on a view. If rendering overlaps in a view with alpha < 1, that view is drawn to an offscreen buffer and then composited it into place, which can be expensive. If the view has no overlapping rendering, the view can draw each primitive with the appropriate alpha value directly. An example of overlapping rendering is a TextView with a background image, such as a Button. An example of non-overlapping rendering is a TextView with no background, or an ImageView with only the foreground image. The default implementation returns true; subclasses should override if they have cases which can be optimized.

Invalidates the specified Drawable.

Call Drawable.jumpToCurrentState() on all Drawable objects associated with this view.

Generate the new Drawable state for this view. This is called by the view system when the cached Drawable state is determined to be invalid. To retrieve the current state, you should use getDrawableState().

Initializes an AccessibilityEvent 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 setAccessibilityDelegate(AccessibilityDelegate) its 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.

Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:

• setParent(View),
• setBoundsInParent(Rect),
• setBoundsInScreen(Rect),
• setPackageName(CharSequence),
• setClassName(CharSequence),
• setContentDescription(CharSequence),
• setEnabled(boolean),
• setClickable(boolean),
• setFocusable(boolean),
• setFocused(boolean),
• setLongClickable(boolean),
• setSelected(boolean),

Subclasses should override this method, call the super implementation, and set additional attributes.

If an View.AccessibilityDelegate has been specified via calling setAccessibilityDelegate(AccessibilityDelegate) its onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.

Called from dispatchPopulateAccessibilityEvent(AccessibilityEvent) giving a chance to this View to populate the accessibility event with its text content. While this method is free to modify event attributes other than text content, doing so should normally be performed in onInitializeAccessibilityEvent(AccessibilityEvent).

Example: Adding formatted date string to an accessibility event in addition to the text added by the super implementation:

 public void onPopulateAccessibilityEvent(AccessibilityEvent event) {
     super.onPopulateAccessibilityEvent(event);
     final int flags = DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_SHOW_WEEKDAY;
     String selectedDateUtterance = DateUtils.formatDateTime(mContext,
         mCurrentDate.getTimeInMillis(), flags);
     event.getText().add(selectedDateUtterance);
 }

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

Set this to true if you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable.

Sets the alpha value that should be applied to the image.

Set the offset of the widget's text baseline from the widget's top boundary. This value is overridden by the setBaselineAlignBottom(boolean) property.

Set whether to set the baseline of this view to the bottom of the view. Setting this value overrides any calls to setBaseline.

Set a tinting option for the image. Assumes SRC_ATOP blending mode.

Apply an arbitrary colorfilter to the image.

Set a tinting option for the image.

Sets whether this ImageView will crop to padding.

Sets the alpha value that should be applied to the image.

Sets a Bitmap as the content of this ImageView.

Sets a drawable as the content of this ImageView.
