How to Control an Activity's Contents from a Service?

I am new to Android

Can anyone provide an example/help on this.

For example having a TextView's contents on an Activity automatically changed by a Service.

I already managed to get the service running, is there a listener I could use on the Activity class?

please please please pr开发者_JS百科ovide examples with answers

Have a look at Application class

class MyApplication extends Application {

  private TextView textView;

  public String getTextView(){
    return textView;
  }
  public void setTextView(TextView textView){
    this.textView = textView;
  }
}

class MyActivity extends Activity {

  @Override
  public void onCreate(Bundle b){
    ...
    MyApplication myApp = ((MyApplication)getApplicationContext());
    TextView textview = myApp.getTextView();
    ...
  }
}

Set global resources(that will be used in whole Application Context including Services) in above manner & you are done!
