Fundamentals

• Android provides the clipboard framework for copying and pasting different types of data. The data could be text, images, binary

stream data or other complex data types.

• It provides the library ofClipboardManagerandClipDataandClipData.itemto use the copying and pasting framework.

Use of Clipboard

• In order to use clipboard framework, need to put data into clip object, and then put that object into system wide clipboard.

• ObjectofClipboardManageris instantiated by calling thegetSystemService() method.

ClipboardManagerclipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

Copying data

• The next thing that is need to do is to instantiate theClipDataobject by calling the respective type of data method of

theClipDataclass.

• In case of text data, thenewPlainText( ) method will be called. After that have to set that data as the clip of

theClipbaoardManagerobject.

Copying data

Implementation:

ClipDataclipdata=ClipData.newPlainText("text", “String”);

clipboard.setPrimaryClip(clipdata);

ClipDataForm

• Text

• URI

• Intent

ClipDataForm

• Text :newPlainText(label,text):

ReturnsaClipDataobject whose singleClipData.Itemobject contains a text string.

• URI :newUri(resolver, label, URI):

• Intent :newIntent(label, intent):

Data Pasting

• In order to paste the data, we will first get the clip by calling thegetPrimaryClip( ) method. And from that click will get the item

inClipData.Itemobject and from the object we will get the data.

ClipDataclipdata=clipboard.getPrimaryClip( );

ClipData.Itemitem =clipdata.getItemAt(0);

String text =item.getText( ).toString( );
