Activity data transfer to service

The activity data interface is responsible for starting the service pack. Service to obtain data. Surgery.

Detailed demo as below:

Package Com.example.android_service_trance;import Android.annotation.suppresslint;import android.app.Activity; Import Android.content.componentname;import Android.content.context;import Android.content.intent;import Android.content.serviceconnection;import Android.os.bundle;import Android.os.ibinder;import Android.os.Parcel; Import Android.os.remoteexception;import android.util.log;import Android.view.menu;import Android.view.View;import Android.view.view.onclicklistener;import Android.widget.button;import Android.widget.textview;import Com.example.android_service_trance. Myservice.localbinder, @SuppressLint ("Recycle") public class Mainactivity extends Activity {private Button bindservice= Null;private button callservice=null;private button communicationservice=null;private TextView tv=null;private Boolean flag=false;//does not feel bound to the object in the private MyService myservice=null;private localbinder binder;//service @overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); SetcoNtentview (R.layout.activity_main); bindservice= (Button) This.findviewbyid (R.id.button1); callservice= (Button) This.findviewbyid (R.id.button2); communicationservice= (Button) This.findviewbyid (R.id.button3); tv= (TextView) This.findviewbyid (R.id.textview1); Bindservice.setonclicklistener (new Onclicklistener () {@Overridepublic void OnClick (View v) {//Get Intent Intent intent=new Intent (MAINACTIVITY.THIS,MYSERVICE.CLASS);//Bind service Bindservice (Intent, connection, context.bind_auto_create);}); Callservice.setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (View v) {if (flag) {int result= Myservice.getrandom (); Tv.settext ("<<<<<<<<" +result);}}); Communicationservice.setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (View v) {// Objects passing values to service Parcel data=parcel.obtain ();d ata.writeint (10086);d ata.writestring ("Li Hua"); Parcel Reply=parcel.obtain (); try {binder.transact (ibinder.last_call_transaction, data, reply, 0);} catch ( RemoteException e) {//TODO Auto-generaTed Catch Blocke.printstacktrace ();} Read data from the service LOG.I ("main<<<<<<<<", reply.readstring ()); LOG.I ("main<<<<<<<<<", Reply.readint () + "");}}); Unbind @overrideprotected void OnStop () {super.onstop (); if (flag) {//unbound unbindservice (connection); flag=false;}} @Overridepublic boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action bar if it is PR Esent.getmenuinflater ().

Service side:
