Service delivers data cases to activity in real time

Demonstrate a case with the following requirements:
Create a thread in the service component that is used to produce numeric values that automatically add 1 every 1 seconds and then display the updated values in real time on the interface.

The steps are as follows:
1, a new Android project, named as demo.
2, create a new service class, for real-time production of numerical values for the interface real-time display.

Package Com.ljq.activity; import Android.app.service;import Android.content.intent;import android.os.IBinder; Import Android.util.log; public class Countservice extends Service { private int count = 0; private Boolea n threaddisable=false;   @Override  public void OnCreate () {  super.oncreate ();      new Thread (New Runnable () {    @Override    public Void Run () {     while (!threaddisable) {     try {       Thread.Sleep (+);      } catch (Interruptedexception e) {       e.printstacktrace ();     }     count++;      LOG.V ("Countservice", "Count is" + count);            //Send broadcast      intent intent=new Intent ();   &Nbsp;  intent.putextra ("Count", count);      intent.setaction (" Com.ljq.activity.CountService ");      sendbroadcast (intent);     }    } &NBSP,}). Start ();  }   @Override  public ibinder onBind (Intent Intent) {  return null; }   @Override  public void OnDestroy () {   Super.ondestroy ();   count=0;  threaddisable = TRUE;  LOG.V ("CountService", "on Destroy ");  }  }

3. Create a new activity class to display the data.

Package Com.ljq.activity; import Android.app.activity;import Android.content.broadcastreceiver;import Android.content.context;import Android.content.intent;import Android.content.intentfilter;import Android.os.bundle;import Android.view.view;import Android.widget.button;import android.widget.EditText;  public class Mainactivity extends Activity { private EditText edittext=null; private myreceiver receiver=null ;       @Override     public void OnCreate (Bundle Savedinstancestate) {        super.oncreate (savedInstanceState);         setcontentview (R.layout.main);                  edittext= (EditText) findViewById ( R.id.edittext);                  //Start Service      &Nbsp;  startservice (New Intent (Mainactivity.this, countservice.class));            //Registered broadcast receiver   receiver=new Myreceiver ();   intentfilter Filter=new Intentfilter ();   filter.addaction ("Com.ljq.activity.CountService");   MainActivity.this.registerReceiver (Receiver,filter);    }           @Override  protected void OnDestroy () {     //End service          stopservice (New Intent (Mainactivity.this, countservice.class));   super.ondestroy ();   }         /**      * get Broadcast data      *      * @author jiqinlin      *     */    public class MyReceiver extends Broadcastreceiver {&NBsp;     @Override      public void onreceive (context context, Intent Intent) {      bundle Bundle=intent.getextras ();       int Count=bundle.getint ("Count"),       edittext.settext (count+ "");          }    }              }

4. Main.xml Layout file

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "android:orientation=" vertical "android:layout_width=" fill_parent "android:layout_height=" Fill_parent " > <edittext android:layout_width= "fill_parent" android:layout_height= "Wrap_content" Android:cursorV Isible= "false" android:editable= "false" android:id= "@+id/edittext"/> </LinearLayout>

5. manifest file

<?xml version= "1.0" encoding= "Utf-8"? ><manifest xmlns:android= "http://schemas.android.com/apk/res/ Android "      package=" Com.ljq.activity "       Android:versioncode= "1"       android:versionname= "1.0" >     <application android:icon= "@drawable/icon" android:label= "@string/app_name" >         <activity android:name= ". Mainactivity "                   android:label= "@string/app_name" >             <intent-filter>                 <action android:name= "Android.intent.action.MAIN"/>                 <category AndroidOid:name= "Android.intent.category.LAUNCHER"/>             </intent-filter>        </activity>   <service android:name = ". Countservice "/>     </application>    <uses-sdk android:minsdkversion= "7"/> </manifest>

The effect is as follows:
