小编div*_*ive的帖子

我看到了这个主题,并按照描述实现了IntentService,但如果我想要更多的那个按钮呢？如何区分按钮？我正在尝试setFlags,但无法在onHandleIntent()方法中读取它:

public static class UpdateService extends IntentService {
...

    @Override
    public void onHandleIntent(Intent intent) {
        ComponentName me = new ComponentName(this, ExampleProvider.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(this);
        manager.updateAppWidget(me, buildUpdate(this));
    }

    private RemoteViews buildUpdate(Context context) {
        RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.main_layout);

        Intent i = new Intent(this, ExampleProvider.class);
        PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
        updateViews.setOnClickPendingIntent(R.id.button_refresh, pi);

        i = new Intent(this, ExampleProvider.class); 
        pi = PendingIntent.getBroadcast(context, 0, i, 0);
        updateViews.setOnClickPendingIntent(R.id.button_about, pi);

        return updateViews;
    }
}

在这一小段代码中我有两个与setOnClickPendingIntent链接的PendingIntent,我可以区分这个意图以进行不同的操作和处理吗？感谢帮助

我在app上有自定义注释引脚:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
    return [kml viewForAnnotation:annotation type:state];
}

我返回自定义视图并为Placemark的annotationView创建setImage,例如:

- (MKAnnotationView *)viewForAnnotation:(id <MKAnnotation>)point type:(int)state
{
    // Find the KMLPlacemark object that owns this point and get
    // the view from it.
    for (KMLPlacemark *placemark in _placemarks) {
        if ([placemark point] == point) 
        {
            UIButton *disclosureButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure]; 
            [[placemark annotationView] setCanShowCallout: YES];            
            [[placemark annotationView] setRightCalloutAccessoryView:disclosureButton];

            if (state == 0)
            {
                [[placemark annotationView] setImage:[UIImage imageNamed:@"ic_pin_tour.png"]];
            }
            else
            {
                [[placemark annotationView] setImage:[UIImage imageNamed:@"ic_pin_point.png"]];
            }

            return [placemark …

尝试在我的iMac(2.4Ghz,4Gb RAM)上使用Eclipse for Android(ADT插件)开发,它非常慢(Eclipse Galileo SR2 x64).
我知道eclipse.ini技巧并做一些改变,如:

-XX:MaxPermSize参数=256米
-Xms256m
-Xmx1024m
-XX:+ UseCompressedOops
-XX:+ AggressiveOpts
-XX:+ UseConcMarkSweepGC

并默认使用Java 1.6:

-Dosgi.requiredJavaVersion = 1.6

但在小项目中仍然有冷冻.即使用50LOC滚动课程也很慢.在同一个项目中,IntellijIdea工作得更快.
有一些秘密法术可以赢吗？

什么来自xml,json,rss,atom格式会产生更少的流量？
