Android解析Plist文件

你好我试图解析包含dict数组的plist文件。我试图使用xmlwise来做到这一点。 plistfile的内容为here

到目前为止,我只在我的活动中使用了这个,并且获取了plistfile的内容,但是如何将内容解析为arraylist?

Map<String, Object> properties = null;
try {
    InputStream inputStream = getResources().openRawResource(R.raw.first_5);
    BufferedReader br = null;
    try {
        br = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }
        properties = Plist.fromXml(sb.toString());
        // TODO do something with the object here
        Log.v("--", properties.values() + " " + properties.size());
        Log.v("--", "OB "+properties.get());
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        br.close();
    }
}

快速提问。 ArrayList的内容应该是什么?我想知道您是否在提及Object地图中的Map<String, Object> properties列表,那么为什么您只能从地图中获取值

Map<String, Object> properties = new HashMap<String, Object>();
List<Object> plist = new ArrayList<Object>(properties.values());

除了检查你的plist之外,结构就像一个Dict根元素和一个Dicts列表。我假设您需要将此作为列表。如果是这样,请考虑使用longevitysoft的Android PList parser。这很简单,开源。它基本上是SAXParser解析Apple PList

然后,您可以遍历此数组并获取适当的对象。在你的xml中它和Dict对象的数组,所以你可以做这样的事情

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

import com.longevitysoft.android.xml.plist.PListXMLHandler;
import com.longevitysoft.android.xml.plist.PListXMLParser;
import com.longevitysoft.android.xml.plist.domain.Array;
import com.longevitysoft.android.xml.plist.domain.Dict;
import com.longevitysoft.android.xml.plist.domain.PList;
import com.longevitysoft.android.xml.plist.domain.PListObject;

public class PlistReader {

    public static void main(String[] args) throws Exception {
        PListXMLParser parser = new PListXMLParser();
        PListXMLHandler handler = new PListXMLHandler();
        parser.setHandler(handler);
        parser.parse(readFile("plist.xml"));
        PList pList = ((PListXMLHandler) parser.getHandler()).getPlist();
        Dict root = (Dict) pList.getRootElement();
        // This Array class is java.util.ArrayList<PListObject> underneath the
        // covers
        Array theList = root.getConfigurationArray("Objects");
        for (PListObject obj : theList) {
            switch (obj.getType()) {
                case DICT:
                    Dict dictionaryObj = (Dict) obj;
                    // dictionaryObj.getConfigurationObject(key);
                    // dictionaryObj.getConfigurationInteger(key);
                    // dictionaryObj.getConfiguration(key);
                    // dictionaryObj.getConfigurationArray(key)
                    break;

                case STRING:
                    com.longevitysoft.android.xml.plist.domain.String stringObj = (com.longevitysoft.android.xml.plist.domain.String) obj;
                    break;

                default:
                    break;
            }
        }
    }

    private static String readFile(String path) throws IOException {
        byte[] encoded = Files.readAllBytes(Paths.get(path));
        return new String(encoded);
    }

}

当我尝试解析你的xml时,我遇到了一些异常。那是因为PListXMLHandler正在检查localName而不是qualifiedName。通过检查startElement()和endElement()方法(如。

)中的localName可以很容易地解决这个问题
if(isEmpty(localName)){
    localName = qName;
}

希望这有帮助。

您还可以尝试使用Google dd-plist.jar库或SAXON解析来解析plist。

完成此转换:

https://code.google.com/p/plist/wiki/Examples http://developer.android.com/reference/javax/xml/parsers/SAXParser.html

您可以使用dd-plist jar来执行此操作,从Google下载dd-plist.jar非常快速。

我正在通过Google代码colud为我工作。 链接在这里。 http://plist.googlecode.com/svn-history/r61/trunk/src/com/dd/plist/XMLPropertyListParser.java
