如何在Android日期选择器中禁用未来日期

Java代码:

mExpireDate.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                // To show current date in the datepicker
                final Calendar mcurrentDate = Calendar.getInstance();
                int mYear = mcurrentDate.get(Calendar.YEAR);
                int mMonth = mcurrentDate.get(Calendar.MONTH);
                int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                 DatePickerDialog mDatePicker = new DatePickerDialog(
                        EventRegisterActivity.this, new OnDateSetListener() {
                            public void onDateSet(DatePicker datepicker,
                                    int selectedyear, int selectedmonth,
                                    int selectedday) {

                                mcurrentDate.set(Calendar.YEAR, selectedyear);
                                mcurrentDate.set(Calendar.MONTH, selectedmonth);
                                mcurrentDate.set(Calendar.DAY_OF_MONTH,
                                        selectedday);
                                SimpleDateFormat sdf = new SimpleDateFormat(
                                        getResources().getString(
                                                R.string.date_card_formate),
                                        Locale.US);

                                mExpireDate.setText(sdf.format(mcurrentDate
                                        .getTime()));
                            }
                        }, mYear, mMonth, mDay);

                mDatePicker.setTitle(getResources().getString(
                        R.string.alert_date_select));
                mDatePicker.show(); …

嗨如何使用下面的逻辑清除片段后堆栈它不工作...

for(int i = 0; i < mFragmentManager.getBackStackEntryCount(); ++i) {            
     mFragmentManager.popBackStack();
}

帮我..

我已经实现了动作栏SearchView,它工作正常,但在屏幕的底部显示了一个浮动文本弹出窗口.看截图:

ListView Java类:

@Override
    public boolean onQueryTextChange(String newText) {

        if (TextUtils.isEmpty(newText)) {
            mListView.clearTextFilter();
        } else {

            // EventAdapterView ca = (EventAdapterView)mListView.getAdapter();
            // ca.getFilter().filter(newText.toString());

            // Filter lFilter = mDataAdapter.getFilter();
            // lFilter.filter("");
            // following line was causing the ugly popup window.
            mListView.setFilterText(newText.toString());

            // EventAdapterView ca = (EventAdapterView)mListView.getAdapter();
            // ca.getFilter().filter(newText.toString());

        }

        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        return true;
    }

适配器类

@Override
    public Filter getFilter() {
        /**
         * A filter object which will filter message key
         * */
        Filter filter …

如何在java中多次调用launch()我被赋予异常"主要错误:java.lang.IllegalStateException:不能多次调用应用程序启动"

我在我的java应用程序中创建了rest cleint,当请求到来之后调用javafx并在完成webview operarion后使用Platform.exit()方法关闭javafx窗口时打开webview.当第二个请求收到此错误时如何重新发送此错误.

JavaFx应用程序代码:

public class AppWebview extends Application  {

    public static Stage stage;

    @Override
    public void start(Stage _stage) throws Exception {

        stage = _stage;
        StackPane root = new StackPane();

        WebView view = new WebView();

        WebEngine engine = view.getEngine();
        engine.load(PaymentServerRestAPI.BROWSER_URL);
        root.getChildren().add(view);
        engine.setJavaScriptEnabled(true);
        Scene scene = new Scene(root, 800, 600);
        stage.setScene(scene);

        engine.setOnResized(new EventHandler<WebEvent<Rectangle2D>>() {
            public void handle(WebEvent<Rectangle2D> ev) {
                Rectangle2D r = ev.getData();
                stage.setWidth(r.getWidth());
                stage.setHeight(r.getHeight());
            }
        });

        JSObject window = (JSObject) engine.executeScript("window");
        window.setMember("app", new BrowserApp());

我有一个启用了CSRF保护的Spring Web应用程序.我可以通过AJAX调用访问RESTful服务,但是当我使用httpurlconnection等其他应用程序访问服务时,我收到401错误(CSRF令牌为null).

我知道要访问RESTful服务,我需要在请求标头中传递令牌,但是如何获取CSRF令牌？

我在显示listview时实现了listview customadapter,它显示了如何重新启动它.
