try {

                    if (success == 1) 
                    {

                        // products found
                        // Getting Array of Products
                        products = json.getJSONArray(TAG_PRODUCTS);

                        // looping through All Products
                        for (int i = 0; i < products.length(); i++) {
                            JSONObject c = products.getJSONObject(i);

                            // Storing each json item in variable
                            String kode = c.getString(KDKMK);
                            String sks = c.getString(SKSMK);
                            String nil = c.getString(NILMK);
                            String nmmk = c.getString(NMKMK);
                            String totalsks = c.getString(TOTSKS);

                            // creating new HashMap
                            HashMap<String, String> map = new HashMap<String, String>();

                            // adding each child node to HashMap key => value
                            map.put(KDKMK, kode);
                            map.put(SKSMK, sks);
                            map.put(NILMK, nil);
                            map.put(NMKMK, nmmk);
                            map.put(TOTSKS, totalsks );

                            // adding HashList to ArrayList
                            productsList.add(map);



                        }
                    }

                protected void onPostExecute(String file_url) {
                // dismiss the dialog after getting all products
                pDialog.dismiss();
                // updating UI from Background Thread
                runOnUiThread(new Runnable() {
                    public void run() {
                        /**
                         * Updating parsed JSON data into ListView
                         * */
                        ListAdapter adapter = new SimpleAdapter(
                                GetTotal.this, productsList,
                                R.layout.customgrid_khs, new String[] { NMKMK, 
                                        SKSMK, NILMK, TOTSKS  },
                                new int[] { R.id.NMKMK, R.id.SKSMK, R.id.NILMK, R.id.total });
                        // updating listview
                        setListAdapter(adapter);

                        sksmkTv.setText(TOTSKS);
                    }
                });

            }

这是我的代码示例。我的列表视图正常工作，数据库中的数据显示在列表视图中。但我想在main_layout.xml上打印值SKSMK，而不是在listview。

我应该添加什么代码，在android上打印SKSMK值：id =“@ + id / sksmk”

谢谢。

Answer 1

首先，您应该在Activity中处理TextView，如下所示：

private TextView sksmkTv;
sksmkTv = (TextView)findViewById(R.id.sksmk);

然后，使用String Object将SKSMK值保存在“try”代码块中。

最后，在“runOnUiThread”中设置文本

sksmkTv.setText(sksmkValue);

在listview之外调用数据
