小编bbZ*_*bbZ的帖子

如果有人可以帮我这个.我下载了AndroidSDK以及android编程所需的一切,我遇到了一些问题(有趣的是说)hello world.

我只是不知道AppManifest中的tarketSdkVersion设置.每当它没有设置为"13"(只是注意到8这是我的minSdkVersion也在工作)应用程序在LogCat中有"遗憾的应用程序停止工作"屏幕:

我不知道目前问题出在哪里.第一次使用xml,我在将ArrayList放入xml文件并从中取出时遇到了一些问题.

我找到了这个,我试着这样做:如何使用XStream将对象列表转换为XML文档

但不幸的是我失败了.这是我到目前为止:拥有ArrayList的类:

public class ElbowList{

private ArrayList<Elbow> elbows = new ArrayList<>();

public ElbowList(){
    elbows = new ArrayList<Elbow>();
}

public void setElbows(ArrayList<Elbow> elbows){
    this.elbows.clear();
    this.elbows = elbows;
}

public ArrayList<Elbow> getElbows() {
    return elbows;
}

public void add(Elbow elbow){
    elbows.add(elbow);
}
}

保存到XML:

MainFrame mainFrame = (MainFrame) SwingUtilities.getWindowAncestor(SetupPanel.this);
            ElbowList elbowList = (ElbowList) mainFrame.getObjects().get(2); //get ElbowList object
            XStream xstream = new XStream();
            xstream.alias("elbow", Elbow.class);
            xstream.alias("elbows", ElbowList.class);
            xstream.addImplicitCollection(ElbowList.class, "elbows", Elbow.class);

            String xml = xstream.toXML(elbowList.getElbows());
            System.out.println(xml);

            try {
                PrintWriter out = new …
