我尝试了很多方法,但他们都一直说该文件不存在,但确实存在。它位于java
文件夹中,但是当它尝试读取它时失败。我已经取出了 JSON 代码,并将其存储到 Cloudboost 中,当我对其进行硬编码时,它可以工作,但是对于超过 1000 个问题和答案,我无法做到这一点......
这是更新的代码:
public String loadJSON() {
String json = null;
try {
InputStream is = this.getAssets().open("QA.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
public void addToTable() throws CloudException, FileNotFoundException, IOException, ParseException {
CloudObject table = new CloudObject("QuestionsAndAnswers");
ArrayList<String> question = new ArrayList<String>();
ArrayList<String> answer = new ArrayList<String>();
ArrayList<Double> earnings = new ArrayList<Double>();
JSONParser jsonParser = new JSONParser();
Object obj = jsonParser.parse( new FileReader( loadJSON() ) );
JSONArray jsonArray = (JSONArray) obj;
for (int i = 0 ; i < jsonArray.size() ; i++) {
JSONObject jsonObject = (JSONObject) jsonArray.get(i);
question.add( (String) jsonObject.get("Question") );
answer.add( (String) jsonObject.get("Answer") );
if ( jsonObject.get("Earnings") != null ) {
earnings.add( (Double) jsonObject.get("Earnings") );
}
}
question.add("Hello" + "?");
answer.add("Hi");
earnings.add(100.00);
question.add("What's up" + "?");
answer.add("Nothing.");
earnings.add(50.00);
for (int i = 0 ; i < question.size() ; i++) {
table.set("question", question.get(i));
table.set("answer", answer.get(i));
table.set("earnings", earnings.get(i));
table.save(new CloudObjectCallback() {
@Override
public void done(CloudObject x, CloudException e) {
if (e != null) {
// Error
Log.i("TABLE ERROR:", e.getMessage());
}
if (x != null) {
// CloudObject
}
}
});
}
}
这是我用来获取的错误:
