我能够创建一个矩形并在其中添加段落和图像。矩形的宽度也不错，但我只想根据段落中的文本设置矩形的高度。此外，我想以特定方式在矩形内添加数据，这就是我在其中创建表的原因。那么如何让表格填满整个矩形。有人可以帮我解决这个问题吗？

        PdfContentByte cb = writer.getDirectContent();

        Rectangle rect = new Rectangle(kBorderInset, document.getPageSize().getHeight()-kPageDisclaimerY,
                document.getPageSize().getWidth()-2 * kBorderInset,700f);
        cb.rectangle(rect);
        cb.stroke();

        rect.setBorder(Rectangle.BOX);
        rect.setBorderWidth(1);
        rect.setBorderColor(BaseColor.BLACK);
        cb.rectangle(rect);

        ColumnText ct = new ColumnText(cb);
        ct.setSimpleColumn(rect);
        ct.addElement(createTable1(auditBundle, context));
        ct.go();

创建表代码

       private static PdfPTable createTable1(AuditBundle auditBundle, Context context) throws 
       DocumentException {
           PdfPTable table = new PdfPTable(3);
           table.setWidthPercentage(100);
           table.getDefaultCell().setUseAscender(true);
           table.getDefaultCell().setUseDescender(true);
           table.getDefaultCell().setFixedHeight(112f);
           table.setWidths(new int[]{1, 2, 1});

    float fntSize, lineSpacing;
    fntSize = 20f;
    lineSpacing = 12f;
    Paragraph paragraph = new Paragraph();
    paragraph.add(new Phrase(lineSpacing,auditBundle.getAudit().auditName,
            FontFactory.getFont(FontFactory.HELVETICA, fntSize)));
    paragraph.setAlignment(Element.ALIGN_LEFT | Element.ALIGN_CENTER);
    paragraph.setPaddingTop(30);
    PdfPCell cell = new PdfPCell(); …

我写到现在的代码如下：

public class HeaderFooterEvent extends PdfPageEventHelper {
    @Override
    public void onStartPage(PdfWriter writer, Document document) {
    }

    @Override
    public void onEndPage(PdfWriter writer, Document document) {
        addHeader(writer, document);
        addHeader2(writer, document);
        addFooter(writer, document);
    }

    void addHeader(PdfWriter writer, Document document){
        try {
            PdfContentByte cb = writer.getDirectContent();

            // the initial rectangle defines the max size of the content
            rect = new Rectangle(10, document.getPageSize().getBottom() + 50,
                    document.getPageSize().getWidth() - 2 * 10, document.getPageSize().getTop() - 50);

     // flip the rectangle if top and bottom were switched
            rect.normalize();

            ColumnText …

我已在我的应用中通过Firebase实施了推送通知.即使从设置中禁用通知,通知也会到来.我为Firebase实施的课程是:

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

            private static final String TAG = "MyFirebaseMsgService";
            @Override
            public void onMessageReceived(RemoteMessage remoteMessage) {

                //Displaying data in log

                Log.e(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
                //Calling method to generate notification

                String to="";
                to = remoteMessage.getData().get("key1");

        //when the notification is disabled then also the notification is coming
     if(notification_enable) {
    sendNotification(remoteMessage.getNotification().getTitle(),remoteMessage.getNotification().getBody(),to);
           }
        }

            //This method is only generating push notification
            //It is same as we did in earlier posts
            private void sendNotification(String title,String messageBody,String to) { …
