我正在使用小部件来显示RSS提要.显示了Feed但我无法通过单击按钮进行更新.在窗口小部件配置xml中设置的更新周期后,列表也不会更新.

你能帮我么？

WidgetProvider

public class WidgetProvider extends AppWidgetProvider {

    //Tag for Logging
    private static final String TAG = "Widget";

    // String to be sent on Broadcast as soon as Data is Fetched
    // should be included on WidgetProvider manifest intent action
    // to be recognized by this WidgetProvider to receive broadcast
    public static final String DATA_FETCHED = "mypackage.DATA_FETCHED";
    public static final String EXTRA_LIST_VIEW_ROW_NUMBER = "mypackage.EXTRA_LIST_VIEW_ROW_NUMBER";
    public static final String WIDGET_BUTTON = "mypackage.WIDGET_BUTTON";

我在我的片段中使用ShowCase View库.我展示了一个手势动画,应该重复,直到用户按下OK按钮.但只显示一次.

每次创建片段时都会显示展示,而不仅仅是一次.

我的代码看起来像这样:

public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        //get display size for slide over screen
        Display display = getActivity().getWindowManager().getDefaultDisplay();
        Point p = new Point();
        display.getSize(p);

        if(!is_tablet()){
            // ShowView Tutorial if on smartphone
            ViewTarget target = new ViewTarget(getView());
            ShowcaseView.ConfigOptions co = new ShowcaseView.ConfigOptions();
            //can only dismiss by button click
            co.hideOnClickOutside = false;
            //show only once
            co.shotType = ShowcaseView.TYPE_ONE_SHOT;
            sv = ShowcaseView.insertShowcaseView(target, getActivity(),
                    R.string.showcase_detail_title, R.string.showcase_detail_message,co);
            // remove circle
            sv.setShowcaseIndicatorScale(0);
            // set black background
            sv.setBackgroundColor(getResources().getColor(R.color.black));
            // make background a …

我想为奇数行和偶数行填充具有不同布局的ListView.它应该如下所示:

我使用两个对象"OddListItem"和"EvenListItem"来存储/访问数据.我不知道如何将两个对象传递给我的自定义listview适配器并获得正确的视图.

我的对象类:

public class OddListItem {

    private String time_start;
    private String time_end;
    private String location;

    public OddListItem(String time_start, String time_end, String location) {
        super();
        this.time_start = time_start;
        this.time_end = time_end;
        this.location = location;
    }

    // getters and setters
    void setTimeStart(String time_start) {
        this.time_start = time_start;
    }

    void setTimeEnd(String time_end) {
        this.time_end = time_end;
    }

    void setLocation(String location) {
        this.location = location;
    }

    public String getTimeStart() {
        return time_start;
    }

    public String getTimeEnd() {
        return time_end;
    }

    public String getLocation() …
