小编Lal*_*lit的帖子

假设我想以某种特定格式打印"Item"及其"price"

abc           2
asdf          4
qwer xyz      5

AND 2,4,5必须像一列一样.

为此我试过 -

StringBuilder sb = new StringBuilder();

sb.append(String.format("%s%25s", "abc","2"));
sb.append(String.format("%s%25s", "asdf","4"));
sb.append(String.format("%s%25s", "qwer xyz","5"));

tv.setText(sb.toString());   //tv is a text view

但输出是 -

abc             2
asdf             4
qwer xyz             5

我想要"abc",在25个空格之后,我想要"5",但它从abc开始计算25个空格

我正在尝试将文本文件上传到我的Dropbox,但它在清单中显示错误.这是我的 Manifest文件和logcat错误,我做错了可以有人帮我请...
