Android Studio develops the foundation of the start service and passes data from activity to service

This example demonstrates starting the service and passing data from the activity to the service, creating a new service and tapping the following code:

Package Com.example.lhb.startservice;import Android.app.service;import Android.content.intent;import    Android.os.ibinder;import Android.view.viewdebug;import Android.widget.toast;public class MyService extends Service {    Private Boolean running=false; Private String data= "default information!!!    "; Public MyService () {} @Override public ibinder onbind (Intent Intent) {//Todo:return the communication        Channel to the service.    throw new Unsupportedoperationexception ("not yet implemented"); } @Override public int onstartcommand (Intent Intent, int flags, int startid) {Data=intent.getstringextra ("D    ATA ");//The intent here is a parameter, not a custom return Super.onstartcommand (intent, flags, Startid);        } @Override public void OnCreate () {super.oncreate ();        Running=true;                New Thread () {@Override public void run () {super.run ();         while (Running) {System.out.println (data);           try {sleep (3000);                    } catch (Interruptedexception e) {e.printstacktrace ();    }}}}.start ();        } @Override public void OnDestroy () {Super.ondestroy ();    Running=false; }}

Main program code:

Package Com.example.lhb.startservice;import Android.content.intent;import Android.support.v7.app.actionbaractivity;import Android.os.bundle;import Android.view.menu;import Android.view.menuitem;import Android.view.view;import Android.widget.edittext;import Android.widget.Toast;public    Class Mainactivity extends Actionbaractivity {private EditText inputtext;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main); Findviewbyid (R.id.btnstartservice). Setonclicklistener (New View.onclicklistener () {@Override public                void OnClick (View v) {inputtext= (EditText) Findviewbyid (R.id.inputtext); if (Inputtext.gettext (). Length () ==0) {Toast.maketext (mainactivity.this), enter the value passed!                    ", Toast.length_short). Show ();                Return                } Intent Intent; Intent=new Intent (MainactivIty.this,myservice.class);                Intent.putextra ("Data", Inputtext.gettext (). toString ());            StartService (Intent);        }        }); Findviewbyid (R.id.btnstopservice). Setonclicklistener (New View.onclicklistener () {@Override public V                OID OnClick (View v) {Intent Intent;                Intent=new Intent (Mainactivity.this,myservice.class);            StopService (Intent);    }        }); }}
