在访问Android的错误原始资源 [英] Accessing wrong raw resource in Android

问题描述

我有以下的code。我的想法是在OnCreate中，我就可以在/ RES一个文本文件/生到我的数据库填充一些类别。

首先一个由记号化线（myCatToken）读取文件，然后每个I再次分裂，以获得ID和名称。

由于某些原因，而不是阅读rat.txt我得到一个完全不同的文件，我不知道为什么。这实际上是读取/ RES /原料目录确实存在的文件，但它的命名一样。

看来，它是与它发送到readTxtFromRaw资源，但我看不出什么不妥的地方。

感谢

  StringTokenizer的myCatToken =新的StringTokenizer（新的String（readTxtFromRaw（R.raw.rat）））;
而（myCatToken.hasMoreTokens（））
{
    StringTokenizer的myCatDataToken =新的StringTokenizer（myCatToken.nextToken（），，）;
    字符串insertString =新的String（插入+ DATABASE_TABLE_CATEGORIES +
            （+ KEY_CATEGORIES_CATID +，+ KEY_CATEGORIES_NAME +）值+
            （+ myCatDataToken.nextToken（+），+ myCatDataToken.nextToken（）+'））;
    db.execSQL（insertString）;
}
 

有关参考包括我这个方法我使用。 mCtx是上下文：

 私人字符串readTxtFromRaw（整数rawResource）抛出IOException异常
{
    为InputStream的InputStream = mCtx.getResources（）openRawResource（rawResource）。
    ByteArrayOutputStream byteArrayOutputStream =新ByteArrayOutputStream（）;    INT I = inputStream.read（）;
    而（ⅰ！= -1）
    {
        byteArrayOutputStream.write（ⅰ）;
        I = inputStream.read（）;
    }
    inputStream.close（）;    返回byteArrayOutputStream.toString（）;
}
 

解决方案

其实我的Eclipse关闭并重新打开它，它工作正常。啧！

I have the following code. My idea is in OnCreate, I'll populate some categories from a text file in /res/raw to my database.

First a tokenize the read file by lines (myCatToken), then each of these I split again to get the id and name.

For some reason, instead of reading rat.txt I'm getting a totally different file and I have no idea why. The file that is actually read does exist in the /res/raw folder, however its named different.

It seems that it has something to do with the resource it sends to readTxtFromRaw, however I don't see whats wrong with it.

Thanks

StringTokenizer myCatToken = new StringTokenizer(new String(readTxtFromRaw(R.raw.rat)));
while(myCatToken.hasMoreTokens())
{
    StringTokenizer myCatDataToken = new StringTokenizer(myCatToken.nextToken(), ",");
    String insertString = new String("insert into " + DATABASE_TABLE_CATEGORIES +
            " (" + KEY_CATEGORIES_CATID + ", " + KEY_CATEGORIES_NAME + ") values " + 
            " (" + myCatDataToken.nextToken() + ", '" + myCatDataToken.nextToken() + "')");
    db.execSQL(insertString);
}

For reference I include this method I'm using. mCtx is Context:

private String readTxtFromRaw(Integer rawResource) throws IOException
{
    InputStream inputStream = mCtx.getResources().openRawResource(rawResource);
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

    int i = inputStream.read();
    while (i != -1)
    {
        byteArrayOutputStream.write(i);
        i = inputStream.read();
    }
    inputStream.close();

    return byteArrayOutputStream.toString();
}

解决方案

Actually I closed Eclipse and reopened it and it works ok. Sheesh!
