我希望通過換行分割字符串，字符串是來自一個數據庫，結構如下：public String getCoin() { String[] columns = new String[]{ KEY_ROWID, KEY_NAME, KEY_QUANTITY, KEY_OUNCES, KEY_VALUE }; Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null); String result = ""; int iRow = c.getColumnIndex(KEY_ROWID); int iName = c.getColumnIndex(KEY_NAME); int iQuantity = c.getColumnIndex(KEY_QUANTITY); int iOunces = c.getColumnIndex(KEY_OUNCES); int iValue = c.getColumnIndex(KEY_VALUE); for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){ result = result + /*c.getString(iRow) + " " +*/ c.getString(iName).substring(0, Math.min(18, c.getString(iName).length())) + "\n"; } c.close(); return result;result.getCoin讀取alphabravocharlie分割字符串后放在一個字符串數組中：String[] separated = result.split("\n"); for (int i = 0; i < separated.length; i++) { chartnames.add("$." + separated[i] + " some text" ); }得到的輸出："$.alphabravocharlie some text"我希望的輸出是這樣："$.alpha some text, $.bravo some text, $.charlie some text"謝謝幫忙了。。

用標準的I/O類解決，有點大材小用：
BufferedReader rdr = new BufferedReader(new StringReader(result));
List<String> lines = new ArrayList<String>();
for (String line = rdr.readLine(); line != null; line = rdr.readLine()) {
lines.add(line);
}
rdr.close();
