Android-----> Multi-Threading Implementation thread, Intentservice application

First set up a intent.xml

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"android:orientation= "vertical"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"    >    <ButtonAndroid:id= "@+id/btnstartnormalservice"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "Start normalservice"        />    <ButtonAndroid:id= "@+id/btnstartintentservice"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "Start intentservice"        /></LinearLayout>

Establish a Myservice.java implementation thread multithreading

 PackageCom.szy.service;ImportAndroid.app.Service;Importandroid.content.Intent;ImportAndroid.os.IBinder;ImportAndroid.util.Log; Public classMyServiceextendsservice{protected Static FinalString TAG = "Intentactivity"; @Override Public voidonCreate () {Super. OnCreate (); } @Override Public voidOnDestroy () {Super. OnDestroy (); } @Override Public intOnstartcommand (Intent Intent,intFlagsintStartid) {        NewMyThread (). Start (); returnStart_sticky; } @Override Publicibinder onbind (Intent Intent) {return NULL; }        Private classMyThreadextendsThread {@Override Public voidrun () {Try{log.i (TAG,"MyService thread ID:" +Thread.CurrentThread (). GetId ()); LOG.I (TAG,"File download ...."); Thread.Sleep (2000); } Catch(interruptedexception e) {e.printstacktrace (); }                    }            }}

and build a Exampleintentservice.java intentservice.

 PackageCom.szy.service;ImportAndroid.app.IntentService;Importandroid.content.Intent;ImportAndroid.util.Log; Public classExampleintentserviceextendsintentservice{protected Static FinalString TAG = "Intentactivity";  PublicExampleintentservice () {Super("Exampleintentservice"); } @Overrideprotected voidonhandleintent (Intent Intent) {Try{log.i (TAG,"MyService thread ID:" +Thread.CurrentThread (). GetId ()); LOG.I (TAG,"File download ...."); Thread.Sleep (2000); } Catch(interruptedexception e) {e.printstacktrace (); }    }}

Finally, there's an activity to build a intentactivity.xml.

Package Com.szy.service;import Android.app.activity;import Android.content.intent;import android.os.Bundle;import Android.util.log;import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.Button;        public class Intentactivity extends activity{protected static final String TAG = "intentactivity";    Private Button Btnstartnormalservice;    Private Button Btnstartintentservice;        @Override public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (r.layout.intent);        Btnstartnormalservice = (Button) Findviewbyid (R.id.btnstartnormalservice);        Btnstartintentservice = (Button) Findviewbyid (R.id.btnstartintentservice);        Btnstartnormalservice.setonclicklistener (listener);    Btnstartintentservice.setonclicklistener (listener);        } Private Onclicklistener Listener=new Onclicklistener () {public void OnClick (View v) {Intent IntenT Switch (V.getid ()) {Case R.id.btnstartnormalservice:intent=new Intent (Intentactivit                Y.this, Myservice.class);                LOG.I (TAG, "Main thread ID:" +thread.currentthread (). GetId ());                StartService (Intent);            Break                Case R.id.btnstartintentservice:intent=new Intent (intentactivity.this, exampleintentservice.class);                LOG.I (TAG, "Main thread ID:" +thread.currentthread (). GetId ());                StartService (Intent);            Break            Default:break; }                    }    };}

Remember to modify ANDROIDMANIFEST.MXL

<?XML version= "1.0" encoding= "Utf-8"?><Manifestxmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Com.szy.service"Android:versioncode= "1"Android:versionname= "1.0">    <USES-SDKandroid:minsdkversion= "8" />    <ApplicationAndroid:icon= "@drawable/icon"Android:label= "@string/app_name">        <ActivityAndroid:name=".
