Annotation popup menu with long-press in Xamarin.Android

QuickMenu is a convenient annotation popup menu that appears when a user long-presses on a blank space or on text contained in a PDFViewCtrl. It extends RelativeLayout and is a child view of PDFViewCtrl.

Action	Menu
Long-press on blank space
Long-press on text

A number of events may be raised when a user interacts with the quick menu. For example, events will be raised when the quick menu is shown, dismissed, or when a quick menu item is clicked. .

If your activity is using PdfViewCtrlTabHostFragment2 for viewing PDF files, you can set your listener by calling:

mPdfViewCtrlTabHostFragment.CurrentPdfViewCtrlFragment.QuickMenuClicked += (sender, e) =>
{
    // Handle click event...
}

mPdfViewCtrlTabHostFragment.CurrentPdfViewCtrlFragment.QuickMenuShown += (sender, e) =>
{
    // Called when the quick menu is shown
}

mPdfViewCtrlTabHostFragment.CurrentPdfViewCtrlFragment.QuickMenuDismissed += (sender, e) =>
{
    // Called when the quick menu is dismissed
}

Or you can register the listener using the ToolManager:

mToolManager.QuickMenuClicked += (sender, e) =>
{
    // Handle click event...
}

mToolManager.QuickMenuShown += (sender, e) =>
{
    // Called when the quick menu is shown
}

mToolManager.QuickMenuDismissed += (sender, e) =>
{
    // Called when the quick menu is dismissed
}

If there are tools that you would like to remove from the quick menu, you can hide them by calling ToolManager.DisableToolMode:

mToolManager.DisableToolMode(new ToolManager.ToolMode[] {
    ToolManager.ToolMode.TextSquiggly,
    ToolManager.ToolMode.TextStrikeout
});

Then, when you long-press on text you will see:

Icon	ToolMode
	RECT_CREATE
	OVAL_CREATE
	POLYLINE_CREATE
	POLYGON_CREATE
	CLOUD_CREATE
	LINE_CREATE
	ARROW_CREATE
	RULER_CREATE
	TEXT_CREATE
	CALLOUT_CREATE
	TEXT_ANNOT_CREATE
	INK_CREATE
	INK_ERASER
	SIGNATURE
	STAMPER
	RUBBER_STAMPER
	FREE_HIGHLIGHTER
	TEXT_HIGHLIGHT
	TEXT_UNDERLINE
	TEXT_SQUIGGLY
	TEXT_STRIKEOUT
	ANNOT_EDIT_RECT_GROUP

If you would like to hide the long press quick menu entirely, you can do so by calling ToolManager.SetDisableQuickMenu. For example:

mToolManager.SetDisableQuickMenu(true);
