问题描述

对不起，琐碎的问题，我有一个 .db的 sqlite3的文件，我是假设取数据，例如它是只读的。但我不知道在哪里可以导入，同时采取这个数据文件的路径，才能连接呢？你能帮助我吗？

Sorry for trivial question, I've a .db sqlite3 file that I'm suppose to take data, e.g. it's read-only. But I'm wondering where to import it, while taking the path of this data file in order to connect it? Can you help me?

推荐答案

在项目中，我有一个称为资产项目下的文件夹，我把我的* .db的存在，并加载这样的数据库：

In my project I have a folder under the project called assets, I put my *.db there and load the database like this:

private static void copyDatabase(String dbname) throws IOException {
        InputStream is = mContext.getAssets().open(dbname);
        String outFileName = DB_PATH + dbname;
        OutputStream out = new FileOutputStream(outFileName);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = is.read(buffer)) > 0) {
            out.write(buffer, 0, length);
        }
        is.close();
        out.flush();
        out.close();
    }
