我正在做一个需要将数据从android发送到数据库的应用程序。我正在使用JSONParser。但是当我启动应用程序时遇到问题,它不会将数据发送到服务器。我得到了“String name = inputName.getText()。toString();”的错误。这是它:
protected String doInBackground(String... args) {
String name = inputName.getText().toString();
String date = inputDate.getText().toString();
String time = inputTime.getText().toString();
String latitude = inputLatitude.getText().toString();
String longitude = inputLongitude.getText().toString();
String contacts = inputContacts.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", name));
params.add(new BasicNameValuePair("date", date));
params.add(new BasicNameValuePair("time", time));
params.add(new BasicNameValuePair("latitude", latitude));
params.add(new BasicNameValuePair("longitude", longitude));
params.add(new BasicNameValuePair("contacts", contacts));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}

正如错误告诉您的那样,您无法在后台线程上调用getText()
。相反,将您的六个getText()
调用移动到AsyncTask
的构造函数中,或者可能移动到onPreExecute()
回调中,以便在主应用程序线程上进行getText()
调用。 / p>
