Android從 HttpResponse (或者InputStream) 獲取字符串內容的代碼

將寫內容過程比較好的內容做個記錄，下面的資料是關於Android從 HttpResponse (或者InputStream) 獲取字符串內容的內容，應該對碼農有些好處。
private StringBuilder inputStreamToString(InputStream is) {
String line = "";
StringBuilder total = new StringBuilder();

BufferedReader rd = new BufferedReader(new InputStreamReader(is));

while ((line = rd.readLine()) != null) { 
    total.append(line); 
}

return total;

}

private String inputStreamToString(InputStream is) {
String s = "";
String line = "";

BufferedReader rd = new BufferedReader(new InputStreamReader(is));

while ((line = rd.readLine()) != null) { s += line; }

return s;

}
