我有一个Android EditText,我想让数字键盘出现.

如果我将android:inputType设置为numberSigned,我会得到数字键盘和键入负数的能力.但是这不会让我使用小数.如果我使用numberDecimal inputType,我可以使用小数而不是负数.

如何获得能够输入小数和负数的数字键盘？

我正在尝试使用以下代码将文本文件上传到Dropbox:

def uploadFile(file):
    f = open('logs/%s.txt' % file)
    response = client.put_file('/%s.txt' % file, f)
    print "Uploaded log file %s" % file

连接到Dropbox工作得非常好,就在我上传文件时我收到了这个错误:
