如何换行分割字符串???

我希望通过换行分割字符串,字符串是来自一个数据库,结构如下:

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读取alphabravocharlie

分割字符串后放在一个字符串数组中:

String[] separated = result.split("\n");
      for (int i = 0; i < separated.length; i++) {
           chartnames.add("$." + separated[i] + " some text" ); 
           }

得到的输出:

"$.alpha
bravo
charlie some text"

我希望的输出是这样:

"$.alpha some text, $.bravo some text, $.charlie some text"

谢谢帮忙了。。

用这个语句:

String lines[] = String.split("\\r?\\n");

用标准的I/O类解决,有点大材小用:

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();
