我想读的所有信息，然后从我的手机各自的详细信息。 为此，我现在用的是开放的我们是这样的：

I want to read all the messages and their respective details from my phone. For this I am using the Uri like this:

Uri sms = Uri.parse("content://sms/");

但我不知道有多少列的数据库，与此URI关联。

But I don't know how many columns in database which are associated with this uri.

我想显示以下信息：

请任何人可以列举总列名？

Please can anybody enumerate the total column names?

推荐答案

您应该能够通过旋转光标并查找自己：

You should be able to rotate through the Cursor and look for yourself:

mCursor = managedQuery(sms, null, null, null, null);

StringBuffer info = new StringBuffer();
for( int i = 0; i < mCursor.getColumnCount(); i++) {
    info.append("Column: " + mCursor.getColumnName(i) + "\n");
}
Toast.makeText(getApplicationContext(), info.toString(), Toast.LENGTH_LONG).show();
