私はmysqlからのデータを表示するためにこのようなコードを持っています.

それはデータを読むことです

protected String doInBackground(String... params) {
            // updating UI from Background Thread
            runOnUiThread(new Runnable() {
                public void run() {
                       // Building Parameters
                //  int success;
                    try {
                        // Building Parameters
                        List<NameValuePair> params = new ArrayList<NameValuePair>();
                        params.add(new BasicNameValuePair("phone", mPhoneNumber));
                        params.add(new BasicNameValuePair("id_store", id_store));

                        // getting store details by making HTTP request
                        // Note that store details url will use GET request
                        JSONObject json = jsonParser.makeHttpRequest(Constants.url_store_detail, "GET", params);

                        // check your log for json response
                        Log.d("Single Store Details", json.toString());

                        // json success tag

                            // successfully received store details
                            JSONArray storeObj = json.getJSONArray("store"); // JSON Array

                            // get first product object from JSON Array
                            JSONObject store = storeObj.getJSONObject(0);

                            // product with this pid found
                            // Edit Text
                            urledit = (EditText) findViewById(R.id.ETurledit);
                            storenameedit = (EditText) findViewById(R.id.ETusernameedit);
                            storedescedit = (EditText) findViewById(R.id.ETdescedit);
                            edittype=(Spinner)findViewById(R.id.Stypeedit);

                            String url = json.getString(TAG_URL);

                            // display store data in EditText
                            urledit.setText(store.getString(TAG_URL));
                            storenameedit.setText(store.getString(TAG_NAME));
                            storedescedit.setText(store.getString(TAG_DESC));               

                            if(store.getString(TAG_TYPE).equals("1")){
                                String mine = store.getString("Wordpress");
                                ArrayAdapter myadap = (ArrayAdapter)edittype.getAdapter();

                                int spinnerpos = myadap.getPosition(mine);
                                edittype.setSelection(spinnerpos);

                            }else{
                                String mine = store.getString("Prestashop");
                                ArrayAdapter myadap = (ArrayAdapter)edittype.getAdapter();

                                int spinnerpos = myadap.getPosition(mine);

                                edittype.setSelection(spinnerpos);


                            }

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            });

            return null;
        }

しかし、このようなエラーが表示されます

これを解決するには?? JSONObject が JSONArray に変換できないというエラーが表示されるため、誰かが私を助けてくれることを願っています。あなたのアドバイスに感謝します

ログを見て、これを使用してください

JSONObject storeObj = json.getJSONObject("store");

それ以外の

JSONArray storeObj = json.getJSONArray("store");

ストアはJSONオブジェクトであるため

JSONObject json = jsonParser.makeHttpRequest(Constants.url_store_detail, "GET", params);

ご覧のとおり、ここでjsonはJSONObjectです。そしてここ

JSONArray storeObj = json.getJSONArray("store");

からJSONObject取得しようとしていますJSONArray。

したがって、jsonをとしてJSONObject宣言する代わりにJSONArray。

次に、storeObjを削除して、次のようにデータを直接取得します

JSONObject store = json.getJSONObject(0);
