CSV缺失值

Question

我正在使用openCSV来读取csv文件，以便为我的Android应用程序充气我的自动完成功能。尽管来自csv的大多数值都已成功读取并且自动完成全文查看，但其中一些值缺失了。＆＃34;例如，程序无法读取csv值＆＃34; Los Angeles，CA＆＃34;，LAX 。

阅读CSV：

  public void readCSV() throws IOException {
      InputStream is = this.getAssets().open("airport-codes.csv");
      InputStreamReader ifr = new InputStreamReader(is, "UTF-8");

      CSVReader reader = new CSVReader (ifr);
      ArrayList<String> srd = new ArrayList<>();

      while ((reader.readNext()) != null)
      {
          nextLine = reader.readNext();
          Log.i("ArrivalTest", nextLine[0] + "- " + nextLine[1]);
          srd.add(nextLine[0] + " - " + nextLine[1]);

      }
      reader.close();
      autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.originCityAutoComp1);
      adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, srd);
      autoCompleteTextView.setAdapter(adapter);
 }

机场codes.csv：

...

"Lorient, France ",LRT
"Los Angeles, CA ",LAX    // Los Angles LAX is in csv file.
"Los Cabos, Mexico ",SJD
...

logcat的：

...
Longview, TX - GGG
Lonorore, Vanuatu - LNE
Lord Howe Island, NS, Australia - LDH
Lorient, France - LRT
Los Cabos, Mexico - SJD      // Los Angles LAX is missing.
Losuia, Papua New Guinea - LSA
Lourdes/Tarbes, France - LDE
...

Answer 1

你的while循环正在从CSV文件中剔除每个奇数编号的数据行并将其丢弃：）

请改为尝试：

while ((nextLine = reader.readNext()) != null) 
{
   Log.i("ArrivalTest", nextLine[0] + "- " + nextLine[1]);
   srd.add(nextLine[0] + " - " + nextLine[1]);
}
