class ExtraRenderingInfo
Class with information of a view useful to evaluate accessibility needs. Developers can refresh the node with the key EXTRA_DATA_RENDERING_INFO_KEY to fetch the text size and unit if it is TextView and the height and the width of layout params from ViewGroup or TextView.
Summary
Public methods
getLayoutSize
fun getLayoutSize(): Size?
Gets the size object containing the height and the width of android.view.ViewGroup.LayoutParams if the node is a ViewGroup or a TextView, or null otherwise. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.
getTextSizeInPx
fun getTextSizeInPx(): Float
Gets the text size if the node is a TextView, or -1 otherwise. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.
| Return |
Float |
the text size of a TextView, or -1 otherwise. |
getTextSizeUnit
fun getTextSizeUnit(): Int
Gets the text size unit if the node is a TextView, or -1 otherwise. Text size returned from getTextSizeInPx in raw pixels may scale by factors and convert from other units. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.
