Android uses the Clipboard to pass data

Using the Clipboard to pass data, you can pass simple data, or you can pass a serializable object.

Let's start with a simple point.

First, add a button to the Mainactivity.xml file.

Privatebutton button; @Overrideprotected voidonCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main); //TODO auto-generated Method StubButton = (Button) This. Findviewbyid (R.id.button); Button.setonclicklistener (NewView.onclicklistener () {@SuppressLint ("Newapi") @Override Public voidOnClick (View v) {//TODO auto-generated Method Stub//first case: Clipboard passes common type data//Clipboardmanager Clipboardmanager = (clipboardmanager) getsystemservice (Context.clipboard_servi CE);//calling the Clipboard service from the Android system//String name = "Jack";//Clipboardmanager.settext (name);//Intent Intent = new Intent (mainactivity.this,otheractivity.class);//startactivity (Intent); //second case: Clipboard transfer serializable objectMyData MyData =NewMyData ("Jack","Beijing"); //Convert an object to a stringBytearrayoutputstream Bytearrayoutputstream =NewBytearrayoutputstream (); String basestring=""; Try{ObjectOutputStream ObjectOutputStream=NewObjectOutputStream (Bytearrayoutputstream);                            Objectoutputstream.writeobject (MyData); Basestring=base64.encodetostring (Bytearrayoutputstream.tobytearray (), base64.default);                        Objectoutputstream.close (); } Catch(Exception e) {//Todo:handle Exception} clipboardmanager Clipboardmanager=(Clipboardmanager) Getsystemservice (Context.clipboard_service);                        Clipboardmanager.settext (basestring); Intent Intent=NewIntent (mainactivity. This, Otheractivity.class);                    StartActivity (Intent);            }                }); }

Before this, of course, you need to create a new object, new Mydata.java

Package Com.example.android_intent3;import java.io.Serializable; Public classMyData implements Serializable {PrivateString age; PrivateString name;  PublicMyData (string age, String name) {super ();  This. Age =Age ;  This. Name =name; } @Override PublicString toString () {return "MyData [age="+ Age +", Name="+ name +"]"; }     PublicString getage () {returnAge ; }     Public voidsetage (String age) { This. Age =Age ; }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     PublicMyData () {//TODO auto-generated Constructor stub    }}

Of course, you also need to add a button to the Mainactivity.xml file

<button        android:id="@+id/button"        android:layout_width= " fill_parent "         android:layout_height="wrap_content"        Android:text =" pass data with clipboard " />

You also need to add a new layout file to the Other.xml file:

<textview android:id="@+id/msg"  android:layout_width="Fill_ Parent"    android:layout_height="fill_parent"></ Textview>

Yes, you have to create a new Otheractivity.java file, add:

PrivateTextView TextView;  Publicotheractivity () {//TODO auto-generated Constructor stub} @SuppressLint ("Newapi") @Overrideprotected voidonCreate (Bundle savedinstancestate) {//TODO auto-generated Method Stubsuper.oncreate (savedinstancestate);        Setcontentview (R.layout.other); //first Case//TextView = (textView) This.findviewbyid (r.id.msg);//Clipboardmanager Clipboardmanager = (clipboardmanager) getsystemservice (context.clipboard_service);//String msgstring = Clipboardmanager.gettext (). toString (); //Textview.settext (msgstring); //The second caseTextView = (TextView) This. Findviewbyid (r.id.msg); //get Android Clipboard serviceClipboardmanager Clipboardmanager =(Clipboardmanager) Getsystemservice (Context.clipboard_service); //get the data in the ClipboardString msgstring =Clipboardmanager.gettext (). toString (); //decoding        byte[] Base64_byte =Base64.decode (msgstring, Base64.default); //Output DataBytearrayinputstream Bytearrayinputstream =NewBytearrayinputstream (Base64_byte); Try{ObjectInputStream ObjectInputStream=NewObjectInputStream (Bytearrayinputstream); MyData MyData=(MyData) objectinputstream.readobject ();        Textview.settext (Mydata.tostring ()); } Catch(Exception e) {//Todo:handle Exception        }    }

Finally, of course you can't forget to add Otheractivity.java to the manifest file.

<activity android:name=". Otheractivity"></activity>
