小编Mur*_*ain的帖子

我在排序包含整数的字符串时遇到问题.如果我使用下面的代码,我会得到如下排序:1some,2some,20some,21some,3some,some

但是我希望它分类如下:1some,2some,3some,20some,21some,some

我怎样才能做到这一点？

谢谢!

Collections.sort(selectedNodes,
    new Comparator<DefaultMutableTreeNode>() {
    @Override
    public int compare(DefaultMutableTreeNode o1,
        DefaultMutableTreeNode o2) {
        return o1.getUserObject().toString()
            .compareTo(o2.getUserObject().toString());
    }
    });

我创建了一个简单的应用程序来测试失败的场景NoClassDefFoundError.

让我们举个例子,我有一些带有Class TestClass的Test1 android项目和一些方法.这个Test1项目我作为test1.jar导出,只导出了带有Class TestClass和的源文件夹classpath.project文件.

在另一个Android项目Test2中,我test1.jar在我的libs文件夹中添加了它.在这个Test2项目中,我有一个类Test2Class,它调用test1.jar类的方法.

在此之后,我test2.jar按照上述步骤将此Test2项目导出为文件.

因此,当我test2.jar在另一个项目中使用它时,我得到了上述错误NoClassDefFoundError.这是jar里面jar的场景.

我应该做什么,所以我能够访问罐子里的罐子.

提前致谢.

我想在Google圈子中完全按照Google Messenger的方式显示圈内字母,如下所示:

我尝试使用这个drawable文件

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
android:shape="oval">
<corners android:radius="10dip"/>
<stroke android:color="@color/primary_color" android:width="2dip"/>
<solid android:color="@color/primary_color"/>

作为文本视图的背景,但这是灾难性的错误.有任何想法吗？

到目前为止,我可以使用adb命令点击,滑动,解锁,安装/卸载和启动应用程序,但无法使用adb命令查找如何执行放大/缩小.

我有一些捏合进/出的坐标,但没有理解如何使用来自终端的adb命令来解雇它们.

例如,我们有命令 - > adb shell输入tap xy所以在这里我们可以用值/坐标替换x和y同样我想知道模拟插入/缩小的方法.

我得到的有关插入的坐标如下.

我是詹金斯的新手.我想知道如何将生成的构建文件附加到作为后期构建操作发送的电子邮件中？

谢谢

我正在使用iTextPdf创建一个签入应用程序.我已经使用图像对象添加了一个图像:

imagePath = "/sdcard/Mugshot.jpg";
Image image = Image.getInstance(imagePath);
image.setAbsolutePosition(165f, 465f);
image.scaleToFit(290f,290f);
document.add(image);

我希望在添加任何内容之前以相同的方式添加图像,因为我预计任何后续内容都会覆盖现有内容.
