是否可以从数据库中检索数据(TAG_NAME)并将其另存为字符串?
private static final String TAG_NAME = "name";
protected String doInBackground(String... args) {
int success;
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("phonenum", phonenum));
JSONObject json = jsonParser.makeHttpRequest(
url_product_details, "GET", params);
Log.d("Single Product Details", json.toString());
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
JSONArray productObj = json
.getJSONArray(TAG_PRODUCT); // JSON Array
JSONObject product = productObj.getJSONObject(0);
我只能将数据显示为textview,但我想将数据保存为字符串。
// product with this pid found
txtwelcome = (TextView) findViewById(R.id.txtname);
// display product data in EditText
txtwelcome.setText(product.getString(TAG_NAME));
我尝试使用它将其保存为字符串,但它不起作用。
username = product.getString(TAG_NAME);
