我正在研究 Dropbox。我看到了文档。这是我显示列表的代码:
Entry entryCheck = mApi.metadata("/", 100, null, true, null);
Log.i("Item Name", entryCheck.fileName());
Log.i("Is Folder", String.valueOf(entryCheck.isDir));
我从 Dropbox 获得了所有列表,但我的问题是
- 如果它是文件或目录,这里 entryCheck.isDir 总是给我真正的价值,所以我怎么知道哪个是文件或哪个是目录?
- 我是如何下载这些文件的。
我试过这个,但它不工作:
private boolean downloadDropboxFile(String dbPath, File localFile,
DropboxAPI<?> api) throws IOException {
BufferedInputStream br = null;
BufferedOutputStream bw = null;
try {
if (!localFile.exists()) {
localFile.createNewFile(); // otherwise dropbox client will fail
// silently
}
DropboxInputStream fin = mApi.getFileStream("dropbox", dbPath);
br = new BufferedInputStream(fin);
bw = new BufferedOutputStream(new FileOutputStream(localFile));
byte[] buffer = new byte[4096];
int read;
while (true) {
read = br.read(buffer);
if (read <= 0) {
break;
}
bw.write(buffer, 0, read);
}
} catch (DropboxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
// in finally block:
if (bw != null) {
bw.close();
}
if (br != null) {
br.close();
}
}
return true;
}
