我已经跑到我的程序在这一个墙上。我已经在互联网上搜索这个问题的解决方案，但我一直没能找到一个，所以在这里..SQLiteDatabaseCorruptException：数据库磁盘映像格式不正确
我想从我的远程服务器下载SQLite数据库。它似乎下载正常，我可以将文件从电话中拉出来查看。它看起来很好。然而，当我的程序试图读取数据库我得到：
android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed
所以我删除服务器上的数据库，并在手机上的DB和我跳到是应该创建数据库，并提交活动它到服务器。它这样做很好，现在数据库已经在手机和服务器上重新创建。我可以打开它们，它们看起来很好。
我重新启动程序，我的微调没有填充数据，我得到了同样的错误。
这是填充微调器的代码。
private void fillSpinner(){
mDbHelper = new myDbAdapter(this);
mDbHelper.open();
Cursor c = mDbHelper.fetchColumns(new String[] {"_id","name"});
if (! c.moveToFirst()){
mDbHelper.createRow("Create Name");
c = mDbHelper.fetchColumns(new String[] {"_id","name"});
}
// create an array to specify which fields we want to display
String[] from = new String[]{"name"};
// create an array of the display item we want to bind our data to
int[] to = new int[]{android.R.id.text1};
// create simple cursor adapter
SimpleCursorAdapter adapter =
new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to);
mDbHelper.close();
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// get reference to our spinner
c.close();
s.setAdapter(adapter);
}
这是fetchColumns方法，仅供参考，因为它用于尝试访问数据库中的数据。
public Cursor fetchColumns(String[] colnames) {
Cursor mCursor = database.query(DATABASE_TABLE, colnames, null,
null, null, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}
Logcat指出我在这个方法的方向。上面提到的错误指向getWritableDatabase（）作为罪魁祸首。数据库不是空的，我可以用sqlite数据库浏览器查看内容。
public SQLiteDatabase open() throws SQLException {
dbHelper = new myDbHelper(context);
database = dbHelper.getWritableDatabase();
return database;
}
这里是下载数据库的方法。
public void downloadFile(String file_name) throws IOException {
URL url = new URL(file_url + file_name);
URLConnection connection = url.openConnection();
InputStream response = connection.getInputStream();
FileOutputStream fos = new FileOutputStream(local_file_path + file_name);
byte data[] = new byte[1024];
fos.write(data);
fos.close();
response.close();
}
任何人有什么想法可能会导致问题？我已经调试和堆栈跟踪，它似乎都来自open（）方法。这里是堆栈跟踪

任何帮助非常感谢！提前致谢！
这里是工作的代码
public void downloadFile(String file_name) throws IOException {
URL url = new URL(file_url + file_name);
URLConnection connection = url.openConnection();
InputStream response = connection.getInputStream();
FileOutputStream fos = new FileOutputStream(local_file_path + file_name);
byte data[] = new byte[1024];
IOUtils.copy(response, fos);
response.close();
}
private void fillSpinner(){
mDbHelper = new myDbAdapter(this);
mDbHelper.open();
Cursor c = mDbHelper.fetchColumns(new String[] {"_id","name"});
if (! c.moveToFirst()){
mDbHelper.createRow("Create Name");
c = mDbHelper.fetchColumns(new String[] {"_id","name"});
c.close();
}
// create an array to specify which fields we want to display
String[] from = new String[]{"name"};
// create an array of the display item we want to bind our data to
int[] to = new int[]{android.R.id.text1};
// create simple cursor adapter
SimpleCursorAdapter adapter =
new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to);
mDbHelper.close();
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// get reference to our spinner
c.close();
s.setAdapter(adapter);
}
我没有关闭游标。
好吧，我增加了行，拿出fos.write（数据）。似乎没有任何错误，并且该文件正在复制，我可以将其拉出并看到条目，但是微调器没有填充？ :( – tricknology
从来没有用光标适配器自己的微调，我不能帮助很多。 –
真棒，修复。感谢您的帮助。张贴编辑与工作代码 – tricknology
