With this style dialog, users can change the annotation color with the advanced color picker or directly select preset styles. The style dialog also provides a recent and a favorite list for quick access.

Show an annotation style dialog

The AnnotationStyleDialogFragment.Builder class allows you to create an AnnotStyleDialogFragment with a specified AnnotStyle. The AnnotStyle represents the initial annotation style to display.

Example

1// 1. Instantiate an AnnotStyle with its constructor
2AnnotStyle annotStyle = new AnnotStyle();
3// 2. Set annotation type to annot style
4annotStyle.setAnnotType(Annot.e_Square);
5// 3. Set blue stroke, yellow fill color, thickness 5, opacity 0.8 to the annotation style.
6annotStyle.setStyle(Color.BLUE, Color.YELLOW, 5f, 0.8f);
7// 4. Instantiate an AnnotStyleDialogFragment.Builder with its constructor
8AnnotStyleDialogFragment.Builder styleDialogBuilder = new AnnotStyleDialogFragment.Builder(annotStyle);
9// 5. Set anchor view if you want the `AnnotStyleDialogFragment` be displayed as a popup window in tablet mode
10styleDialogBuilder.setAnchorView(myButton);
11// 6. Build AnnotStyleDialogFragment with the arguments supplied to this builder.
12AnnotStyleDialogFragment annotStyleDialog = styleDialogBuilder.build();

Afterwards, to show an annotation style dialog call show(FragmentManager). Similarly, to dismiss the annotation style dialog programmatically call dismiss().

Listen to annotation style changes

You can listen to annotation style changes by setting an OnAnnotStyleChangeListener to your AnnotStyleDialogFragment using setOnAnnotStyleChangeListener. The AnnotStyleDialogFragment raises an event when a style change occurs (such as a color change, thickness change, text color change, etc., allowing you to define custom behavior for such events.

To learn about changing annotation style, see the change annotation properties guide.
