Radiography provides a utility class to pretty print a view hierarchy.
Add the radiography dependency to your app"s build.gradle file:
dependencies {
implementation "com.squareup.radiography:radiography:2.0.0"
}Radiography.scan() returns a pretty string rendering of the view hierarchy of all windows managed by the current process.
// Render the view hierarchy for all windows.
val prettyHierarchy = Radiography.scan()
// Include the text content from TextView instances.
val prettyHierarchy = Radiography.scan(stateRenderers = defaultsIncludingPii)
// Append custom attribute rendering
val prettyHierarchy = Radiography.scan(stateRenderers = defaultsNoPii +
stateRendererFor<LinearLayout> {
append(if (it.orientation == LinearLayout.HORIZONTAL) "horizontal" else "vertical")
})You can print a subset of the view hierarchies.
// Extension function on View, renders starting from that view.
val prettyHierarchy = someView.scan()
// Render only the view hierarchy from the focused window, if any.
val prettyHierarchy = Radiography.scan(viewFilter = FocusedWindowViewFilter)
// Filter out views with specific ids.
Radiography.scan(viewFilter = SkipIdsViewFilter(R.id.debug_drawer))
// Combine view filters.
Radiography.scan(viewFilter = FocusedWindowViewFilter and MyCustomViewFilter())
