blackberry - 如何在此自定义对话框上设置按钮的操作？

Question

我制作了一个自定义对话框，如下所示：

public class CustomDialog extends Dialog {
     public CustomDialog(String s) {
    super(s, new String[] {"View","Cancel"}, new int [] {1,2}, 1,         Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION), Manager.FOCUSABLE);

    }

如何设置“查看按钮”和“取消按钮”的操作？我搜索并没有找到我必须做的事情。请帮我 ！

Answer 1

将 a 附加DialogClosedListener到您的CustomDialogusing Dialog.setDialogClosedListener(). 当有人单击任一按钮时，DialogClosedListener.dialogClosed()将调用该方法并将按钮索引作为choice参数传递。

查看此代码..这可能会对您有所帮助..

import net.rim.device.api.ui.component.ButtonField;
import net.rim.device.api.ui.component.Dialog;
import net.rim.device.api.ui.container.HorizontalFieldManager;

public class CustomAlertDialog extends Dialog {


    public CustomAlertDialog() {
        super("Your Custom message for Dialoug" , null, null, Dialog.DISCARD, null, Dialog.VERTICAL_SCROLL);

        HorizontalFieldManager hfm = new HorizontalFieldManager();

        ButtonField view = null;

        view = new ButtonField("view") {
            protected boolean navigationClick(int status, int time) {
            // do what ever you want
            return true;
            }

            protected boolean keyChar(char key, int status, int time) {
            // do what ever you want
            return true;
            }
        };

        ButtonField cancel = null;
        cancel = new ButtonField("Cancel") {
            protected boolean navigationClick(int status, int time) {
            // do what ever you want
            return true;
            }

            protected boolean keyChar(char key, int status, int time) {
            // do what ever you want
            return true;
            }
        };
    hfm.add(view);
    hfm.add(cancel);

    this.add(hfm);
    }
}
