- 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。。
解决方案
用这个语句:
String lines[] = String.split("\r?\n");
解决方案二:
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();
