获得在Android的源代码包的子文件夹名和文件名列表 [英] Getting list of subfolders name and files name in android source package

问题描述

我正在开发用于存储SQL文件更新SQLite数据库Android应用程序。并且SQL脚本将运行在用户按下特定的按钮。这就是我把我的SQL文件

I'm developing an android application that store sql files to update the sqlite database. And that sql script will run when user push certain button. This is where i put my sql files

到目前为止，我一直在使用这种解决方案来运行我的脚本： 首先，我映射更新资源作为update.xml

So far i've been using this solution to run my script: First, mapping my update to resource as update.xml

<resources>    

    <string name="update_list">
        v2_9_11
    </string>

    <string-array name="v2_9_11">
        <item>1_AlterTable_wapactivity</item>
    </string-array>

</resources>

和获得使用这种方法的文件中的SQL脚本：

And get the sql script inside the file with this method :

private void runScript(String version_name){
        try{
            String[] sql_list = mGap.getResources().getStringArray(getArrayIdentifier(mGap, version_name));
            for (String sql : sql_list) {
                InputStream in =  getClass().getResourceAsStream("/com/ods/scm/script/update/"+version_name+"/"+sql+".sql");
                Reader fr = new InputStreamReader(in, "utf-8");
                BufferedReader br = new BufferedReader(fr);
                String s="";
                String baris;
                while((baris=br.readLine())!=null){
                    s+=baris;
                 }
                mDbHelper.executeStatement(s);
            }
            insertUpdate(version_name);
        }
        catch(Exception e){
            System.out.println(e.getMessage());
        }
    }

我从update.xml字符串VERSION_NAME和String [] sql_list文件名。 问题是，我想VERSION_NAME（在这种情况下v2_9_11从文件夹中更新子文件夹名称）和SQL文件名（在这种情况下1_AlterTable_wapactivity.sql），而它update.xml映射。可以ayone帮帮我吗？

I get the String version_name and String[ ] sql_list file name from update.xml. The problem is, i want to get version_name ( in this case v2_9_11 as subfolder name from folder update ) and sql file name ( in this case 1_AlterTable_wapactivity.sql ) without mapping it in update.xml. Can ayone help me?

修改
或者，任何人都可以直接我如何自动映射到update.xml当构建应用程序？

EDIT
Or can anyone direct me how to automatically mapping it to update.xml when build the application?

推荐答案

抱歉的是，我刚才把它放在赏金，但我能解决这个问题由我自己在很短的时间我把它放在赏金后。总之，我的解决办法是打开的apk文件在Android设备内（数据/应用/ .... APK）作为一个zip流。然后列出所有以 COM / ODS / SCM /脚本/更新文件。在这里，我的方法来获取开始使用它的所有文件：

Sorry all, i just now put it in bounty but i'm able to resolve it by myself by the short time after i put it in bounty. Anyway, my solution is to open the apk file that inside the android device (data/app/....apk) as a zip stream. Then list all the file that start with com/ods/scm/script/update. Here my method to get all file that start with it :

public ArrayList openApk(String filePath){
  ArrayList<String> list = new ArrayList<String>();
  FileInputStream fis = null;
  ZipInputStream zipIs = null;
  ZipEntry zEntry = null;
  try {
      fis = new FileInputStream(filePath);
      zipIs = new ZipInputStream(new BufferedInputStream(fis));
      while((zEntry = zipIs.getNextEntry()) != null){
        if(zEntry.getName().startsWith("com/ods/scm/script/update/"))
          list.add(zEntry.getName());
      }
      zipIs.close();
  } catch (FileNotFoundException e) {
      e.printStackTrace();
  } catch (IOException e) {
      e.printStackTrace();
  }
  return list;
}
