Overview

Builder for constructing a DropHelper.Options instance.

Summary

Constructors

Methods

Builds a new DropHelper.Options instance.

Returns:

A new DropHelper.Options instance.

Enables you to specify the elements contained within the drop target. To ensure proper drop target highlighting, all EditText elements in the drop target view hierarchy must be included in a call to this method. Otherwise, an EditText within the target, rather than the target view itself, acquires focus during the drag and drop operation.

If the user is dragging text data and URI data in the drag and drop ClipData, one of the EditText elements in the drop target is selected to handle the text data. Selection is based on the following order of precedence:

1. The EditText (if any) on which the ClipData was dropped
2. The EditText (if any) that contains the text cursor (caret)
3. The first EditText provided in editTexts

To set the default EditText, make it the first argument of the editTexts parameter. For example, if your drop target handles images and contains two editable text fields, T1 and T2, make T2 the default by calling addInnerEditTexts(T2, T1).

Note: Behavior is undefined if EditTexts are added to or removed from the drop target after this method has been called.

See DropHelper for more information.

Parameters:

editTexts: The EditText elements contained in the drop target.

Returns:

This DropHelper.Options.Builder instance.

Sets the color of the drop target highlight. The highlight is shown during a drag and drop operation when data is dragged over the drop target and a MIME type in the matches a MIME type provided to DropHelper#configureView.

Note: Opacity, if provided, is ignored.

Parameters:

highlightColor: The highlight color.

Returns:

This DropHelper.Options.Builder instance.

Sets the corner radius of the drop target highlight. The highlight is shown during a drag and drop operation when data is dragged over the drop target and a MIME type in the matches a MIME type provided to DropHelper#configureView.

Parameters:

highlightCornerRadiusPx: The highlight corner radius in pixels.

Returns:

This DropHelper.Options.Builder instance.

Sets whether or not the app should respond to drag events when the drag operation contains . By default, the app does not respond to drag events that have local state. Setting local state is only possible when the drag operation originated from the current activity.

Note: To elicit the default behavior of ignoring drags from the same activity as the drop target, the local state supplied when starting the drag (via View or using DragStartHelper) must be non-null.

Parameters:

acceptDragsWithLocalState: Whether or not to accept drag events with non-null local state.

Returns:

This DropHelper.Options.Builder instance.
