我正在更新 JSONArray 內的 JSONObject 中的值，當更改值時，會更新所有 JSONArray 中的值。有人知道為什么嗎？ public static void uploadMediaWithThumbnail( final LeagueActivity.UploadingCallback call, final long leagueId, final JSONArray information, final JsonHttpResponseHandler handler) { final AtomicInteger receivedCount = new AtomicInteger(); receivedCount.set(0); call.progressCall(10); getMediaUploadUrl(leagueId, information, new JsonHttpResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, JSONObject response) { try { call.progressCall(20); final JSONArray allData = response.getJSONArray("upload_data"); AsyncHttpClient[] clients = new AsyncHttpClient[allData.length()*2]; JSONArray jarr = information; for (int i = 0; i < allData.length(); i++ ) { final String uploadUrl = allData.getJSONObject(i).getString("content_url"); final String previewUrl = allData.getJSONObject(i).getString("preview_url"); jarr.getJSONObject(i).put("content", uploadUrl); jarr.getJSONObject(i).put("preview", previewUrl); } final JSONArray newInfo = shallowCopy(jarr); Log.d("Log1", newInfo.getJSONObject(1).getString("content")); Log.d("Log2", newInfo.getJSONObject(0).getString("content"));記錄 Log1 和 Log2 時，它們包含相同的鏈接信息是這樣的數(shù)據(jù)[{"type":"video","format":"mp4","preview_format":"jpg"}, {"type":"video","format":"mp4","preview_format":"jpg"}]AllData 是從 REST HTTP 調用接收到的信息，并且與信息具有相同的長度

您想要將信息項添加到 JSONObject 中，然后將該對象添加到 JSONArray 中。
JSONArray jarr = information;
for (int i = 0; i < allData.length(); i++ ) {
final String uploadUrl = allData.getJSONObject(i).getString("content_url");
final String previewUrl = allData.getJSONObject(i).getString("preview_url");
JSONObject object = new JSONObject();
object.put("content", uploadUrl);
object.put("preview", previewUrl);
jarr.put(i, object);
}
在 for 循環(huán)之后，您可以從鍵中獲取值。
或者，如果 jarr 已經有對象......
JSONArray jarr = information;
for (int i = 0; i < allData.length(); i++ ) {
final String uploadUrl = allData.getJSONObject(i).getString("content_url");
final String previewUrl = allData.getJSONObject(i).getString("preview_url");
JSONObject object = new jarr.getJSONObject(i);
object.put("content", uploadUrl);
object.put("preview", previewUrl);
jarr.put(i, object);
}
這沒有經過測試，但應該可以工作。哈哈

嘗試這樣，
JSONArray jsonArray;
try {
//here replace with your data object
jsonArray = new JSONArray(" [{\"type\":\"video\",\"format\":\"mp4\",\"preview_format\":\"jpg\"}, {\"type\":\"video\",\"format\":\"mp4\",\"preview_format\":\"jpg\"}]");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
jsonObject.put("content", "test value " + i);
}
Log.d("Print test", jsonArray.getJSONObject(0).toString());
Log.d("Print test", jsonArray.getJSONObject(1).toString());
} catch (
JSONException e) {
e.printStackTrace();
}
