将json时间戳转换为android日期

我想将带有时区的json时间戳转换为在Android设备上显示的字符串。

Json时间戳是:/Date(1379488920000+0200)/

输出应考虑Android设备所在的时区和设备上配置的格式(AM / PM或24小时)。输出应仅显示小时和分钟。

此代码有效,但它没有处理时区,设备时区和设备格式:

String timestamp = jsonDate.split("\\(")[1].split("\\+")[0];
String departure = SimpleDateFormat.getTimeInstance(SimpleDateFormat.SHORT)
                        .format(new Date(Long.parseLong(timestamp)));

我最终在构造函数中设置了上下文,并从重写的run函数传递它。

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new FetchData(context, appWidgetManager), 1, 30000);
}

private class FetchData extends TimerTask {
    RemoteViews remoteViews;
    AppWidgetManager appWidgetManager;
    ComponentName thisWidget;
    Context thisContext = null;

    public FetchData(Context context, AppWidgetManager appWidgetManager) 
    {
        thisContext = context;
        this.appWidgetManager = appWidgetManager;
        remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
        thisWidget = new ComponentName(context, HelloWidget.class);
    }

    @Override
    public void run() 
    {
        String restUrl = TrainFromSki;
        remoteViews.setTextViewText(R.id.widget_textview, GetTextData(thisContext, restUrl));
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
    }
}

在GetTextData内部,我按照设备设置格式化日期:

String jsonDate = "/ Date(1379488920000+0200) /";
String timestamp = jsonDate.split("\\(")[1].split("\\+")[0];

String departure = DateFormat.getTimeFormat(context)
           .format(new Date(Long.parseLong(timestamp)));
