我试图破译以下功能:
Subscription getCar(id, Observer<Car> observer) {
return getCarDetails(id, new Observer<CarDetails> {
@Override
onNext(CarDetails details) {
observer.onNext(details.getCar());
} });
}

我从http://blog.danlew.net/2014/09/15/grokking-rxjava-part-1/获得了rxjava的一个很好的介绍,但它只是提到了Observer,说你将使用Subscriber的大部分内容.从Observable发出的消费品的时间.
有人可以向我解释
Javadoc使它看起来像订阅者.订阅者的javadoc说它实现了观察者和订阅.我很迷茫.

我指定了com.myapp.android.debug,因为我在Android Studio的logcat查看器中看到了它,尽管我实际上没有debug文件夹。我在“ com”的父目录中运行了pidcat脚本;java / com / myapp / android
我有分配给 onUpdate 的变量,需要访问我的应用程序小部件提供程序类的 onReceive 的值。
public class MyWidgetProvider extends AppWidgetProvider {
private static String name;
private static SharedPreferences myPrefs;
private static final String START_ACTION = "start";
@Override
public void onUpdate(final Context context, final AppWidgetManager appWidgetManager,
final int[] appWidgetIds) {
views = new RemoteViews(context.getPackageName(), R.layout.layout_widget);
Intent intent1 = new Intent(context, MyAppWidgetProvider.class);
providerIntent.setAction(START_ACTION);
pendingIntent = PendingIntent.getBroadcast(context, 0, providerIntent, 0);
....
myPrefs = Context.getSharedPreferences("PrefsName", 0x0000);
name = "new name";
networkClient.requestItem(name, new JsonHandler {
@Override
public void requestSuccess(JSONObject resp) {
views.setOnClickPendingIntent(R.section, pendingIntent);
