ClipData is a complex type containing one or more Item instances, * each of which can hold one or more representations of an item of data. * For display to the user, it also has a label.

* *

A ClipData contains a {@link ClipDescription}, which describes * important meta-data about the clip. In particular, its * {@link ClipDescription#getMimeType(int) getDescription().getMimeType(int)} * must return correct MIME type(s) describing the data in the clip. For help * in correctly constructing a clip with the correct MIME type, use * {@link #newPlainText(CharSequence, CharSequence)}, * {@link #newUri(ContentResolver, CharSequence, Uri)}, and * {@link #newIntent(CharSequence, Intent)}. * *

Each Item instance can be one of three main classes of data: a simple * CharSequence of text, a single Intent object, or a Uri. See {@link Item} * for more details. * *

*

Implementing Paste or Drop

* *

To implement a paste or drop of a ClipData object into an application, * the application must correctly interpret the data for its use. If the {@link Item} * it contains is simple text or an Intent, there is little to be done: text * can only be interpreted as text, and an Intent will typically be used for * creating shortcuts (such as placing icons on the home screen) or other * actions. * *

If all you want is the textual representation of the clipped data, you * can use the convenience method {@link Item#coerceToText Item.coerceToText}. * In this case there is generally no need to worry about the MIME types * reported by {@link ClipDescription#getMimeType(int) getDescription().getMimeType(int)}, * since any clip item can always be converted to a string. * *

More complicated exchanges will be done through URIs, in particular * "content:" URIs. A content URI allows the recipient of a ClipData item * to interact closely with the ContentProvider holding the data in order to * negotiate the transfer of that data. The clip must also be filled in with * the available MIME types; {@link #newUri(ContentResolver, CharSequence, Uri)} * will take care of correctly doing this. * *

For example, here is the paste function of a simple NotePad application. * When retrieving the data from the clipboard, it can do either two things: * if the clipboard contains a URI reference to an existing note, it copies * the entire structure of the note into a new note; otherwise, it simply * coerces the clip into text and uses that as the new note's contents. * * {@sample development/samples/NotePad/src/com/example/android/notepad/NoteEditor.java * paste} * *

In many cases an application can paste various types of streams of data. For * example, an e-mail application may want to allow the user to paste an image * or other binary data as an attachment. This is accomplished through the * ContentResolver {@link ContentResolver#getStreamTypes(Uri, String)} and * {@link ContentResolver#openTypedAssetFileDescriptor(Uri, String, android.os.Bundle)} * methods. These allow a client to discover the type(s) of data that a particular * content URI can make available as a stream and retrieve the stream of data. * *

For example, the implementation of {@link Item#coerceToText Item.coerceToText} * itself uses this to try to retrieve a URI clip as a stream of text: * * {@sample frameworks/base/core/java/android/content/ClipData.java coerceToText} * * *

Implementing Copy or Drag

* *

To be the source of a clip, the application must construct a ClipData * object that any recipient can interpret best for their context. If the clip * is to contain a simple text, Intent, or URI, this is easy: an {@link Item} * containing the appropriate data type can be constructed and used. * *

More complicated data types require the implementation of support in * a ContentProvider for describing and generating the data for the recipient. * A common scenario is one where an application places on the clipboard the * content: URI of an object that the user has copied, with the data at that * URI consisting of a complicated structure that only other applications with * direct knowledge of the structure can use. * *

For applications that do not have intrinsic knowledge of the data structure, * the content provider holding it can make the data available as an arbitrary * number of types of data streams. This is done by implementing the * ContentProvider {@link ContentProvider#getStreamTypes(Uri, String)} and * {@link ContentProvider#openTypedAssetFile(Uri, String, android.os.Bundle)} * methods. * *

Going back to our simple NotePad application, this is the implementation * it may have to convert a single note URI (consisting of a title and the note * text) into a stream of plain text data. * * {@sample development/samples/NotePad/src/com/example/android/notepad/NotePadProvider.java * stream} * *

The copy operation in our NotePad application is now just a simple matter * of making a clip containing the URI of the note being copied: * * {@sample development/samples/NotePad/src/com/example/android/notepad/NotesList.java * copy} * *

Note if a paste operation needs this clip as text (for example to paste * into an editor), then {@link Item#coerceToText(Context)} will ask the content * provider for the clip URI as text and successfully paste the entire note. */ public class ClipData implements Parcelable { static final String[] MIMETYPES_TEXT_PLAIN = new String[] { ClipDescription.MIMETYPE_TEXT_PLAIN }; static final String[] MIMETYPES_TEXT_HTML = new String[] { ClipDescription.MIMETYPE_TEXT_HTML }; static final String[] MIMETYPES_TEXT_URILIST = new String[] { ClipDescription.MIMETYPE_TEXT_URILIST }; static final String[] MIMETYPES_TEXT_INTENT = new String[] { ClipDescription.MIMETYPE_TEXT_INTENT }; final ClipDescription mClipDescription; final Bitmap mIcon; final ArrayList mItems; /** * Description of a single item in a ClipData. * *
