首先我有两个阵列 JSONObject类型的ArrayList jsonArrayResponse，jsonArraySubResponse
注意：两个数组都具有相同的大小
这是我的代码，用于获取并将位置数据插入数组：
for (int i = 0; i<jsonArrayResponse.size() - 1; i++) {
try {
JSONObject objectDictionary = jsonArrayResponse.get(i);
JSONObject objectSubDictionary = jsonArraySubResponse.get(i);
PlaceObject placeObject = new PlaceObject();
placeObject.setPlace_id(objectDictionary.getString("place_id"));
placeObject.setLat(objectDictionary.getJSONObject("geometry").getJSONObject("location").getDouble("lat"));
placeObject.setLng(objectDictionary.getJSONObject("geometry").getJSONObject("location").getDouble("lng"));
placeObject.setName(objectDictionary.getString("name"));
if (objectDictionary.has("photos")) {
JSONObject photoReferenceObject = objectDictionary.getJSONArray("photos").getJSONObject(0);
if (photoReferenceObject.has("photo_reference")) {
placeObject.setPhotoReference(photoReferenceObject.getString("photo_reference"));
}
}
if (objectSubDictionary.has("vicinity")) {
placeObject.setVicinity(objectSubDictionary.getString("vicinity"));
}
if (objectSubDictionary.has("formatted_address")) {
placeObject.setFormatted_address(objectSubDictionary.getString("formatted_address"));
}
if (objectSubDictionary.has("formatted_phone_number")) {
placeObject.setFormatted_phone_number(objectSubDictionary.getString("formatted_phone_number"));
}
if (objectSubDictionary.has("international_phone_number")) {
placeObject.setInternational_phone_number(objectSubDictionary.getString("international_phone_number"));
}
if (objectSubDictionary.has("url")) {
placeObject.setUrl(objectSubDictionary.getString("url"));
}
if (objectSubDictionary.has("website")) {
placeObject.setWebsite(objectSubDictionary.getString("website"));
}
if (objectSubDictionary.has("reviews")) {
ArrayList<Reviews> reviews = new ArrayList<Reviews>();
for (int j = 0; j<objectSubDictionary.getJSONArray("reviews").length(); j++) {
Reviews reviewObject = new Reviews();
JSONObject review = objectSubDictionary.getJSONArray("reviews").getJSONObject(j);
reviewObject.setAuthor_name(review.getString("author_name"));
if (review.has("rating")) {
reviewObject.setRating(review.getString("rating"));
}
reviewObject.setText(review.getString("text"));
if (review.has("type")) {
reviewObject.setType(review.getString("type"));
}
reviews.add(reviewObject);
}
placeObject.setReviews(reviews);
}
if (objectDictionary.has("opening_hours")) {
ArrayList<String> days = new ArrayList<String>();
for (int z = 0; z<objectDictionary.getJSONObject("opening_hours").getJSONArray("reviews").length(); z++) {
String day = objectDictionary.getJSONObject("opening_hours").getJSONArray("reviews").getString(z);
days.add(day);
}
placeObject.setWeekday_text(days);
}
if (objectDictionary.has("opening_hours")) {
if (objectDictionary.getJSONObject("opening_hours").has("open_now")) {
placeObject.setOpen_now(objectDictionary.getJSONObject("opening_hours").getBoolean("open_now"));
}
}
Float distanceInKilometers = distance(objectDictionary.getJSONObject("geometry").getJSONObject("location").getDouble("lat"), objectDictionary.getJSONObject("geometry").getJSONObject("location").getDouble("lng"), Global.loc.getLatitude(), Global.loc.getLongitude()) / 1000;
placeObject.setDistance(distanceInKilometers.doubleValue());
if (objectDictionary.has("rating")) {
placeObject.setRating(objectDictionary.getDouble("rating"));
}
if (objectDictionary.has("price_level")) {
placeObject.setPrice_level(objectDictionary.getInt("price_level"));
}
placeObjects.add(placeObject);
if (i == jsonArrayResponse.size() - 1) {
this.placeObjectsResopones = placeObjects;
this.placeObjects = placeObjects;
}
} catch (JSONException e) {
e.printStackTrace();
}
}

我的问题是我弄乱了数据，我认为如果数据需要时间来处理它会跳过。如何改进它以确保我获得一个位置对象的所有数据？
答案 0 :(得分：1)
我注意到了
在你的循环中这种情况不会发生
if (i == jsonArrayResponse.size() - 1) {
...
}
因为你的循环不会继续，直到i == jsonArrayResponse.size（） - 1
尝试在循环行中添加=，如此
for (int i = 0; i <= jsonArrayResponse.size() - 1; i++) { ...}
也许这就是缺少数组中最后一个元素的原因
答案 1 :(得分：0)
请提供样本数据。我会尝试使用GSON。
