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 of ClipboardManager and ClipData and ClipData.item to
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.
• Object of ClipboardManager is instantiated by calling the getSystemService()
method.
ClipboardManager clipboard = ( ClipboardManager ) getSystemService (CLIPBOARD_SERVICE);
Copying data
• The next thing that is need to do is to instantiate the ClipData object by calling
the respective type of data method of the ClipData class.
• In case of text data, the newPlainText ( ) method will be called. After that have
to set that data as the clip of the ClipbaoardManager object.
Copying data
Implementation:
ClipData clipdata = ClipData.newPlainText("text", “String”);clipboard.setPrimaryClip(clipdata);
ClipData Form
• Text
• URI
• Intent
ClipData Form
• Text : newPlainText(label, text):
Returns a ClipData object whose single ClipData.Item object contains a text string.
• URI : newUri(resolver, label, URI):
Returns a ClipData object whose single ClipData.Item object contains a URI.
• Intent : newIntent(label, intent):
Returns a ClipData object whose single ClipData.Item object contains Intent.
Data Pasting
• In order to paste the data, we will first get the clip by calling the getPrimaryClip
( ) method. And from that click will get the item in ClipData.Item object and
from the object we will get the data.
ClipData clipdata = clipboard.getPrimaryClip ( );ClipData.Item item = clipdata.getItemAt (0);
String text = item.getText ( ).toString ( );
