我的活動無法將數據從Mysql顯示到Edittext。無法將數據從Mysql傳遞到EditText
當我選擇在我的項目
在我的logcat一個數據，它只是錯誤，我可以接收單數據，但不能進入我的EDITTEXT。
這裏是我的源：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.createperson);
firstname = (EditText) findViewById(R.id.editcreatefirstname);
middlename = (EditText) findViewById(R.id.editmiddlename);
lastname = (EditText) findViewById(R.id.editlastname);
alias = (EditText) findViewById(R.id.editaliasname);
gender = (EditText) findViewById(R.id.editgender);
city = (EditText) findViewById(R.id.editcity);
date = (EditText) findViewById(R.id.editdate);
month = (EditText) findViewById(R.id.editmonth);
year = (EditText) findViewById(R.id.edityear);
noID = getIntent().getStringExtra(TAG_PID);
new LoadAllProducts().execute();
}
class LoadAllProducts extends AsyncTask<String, String, String>{
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(SingleView.this);
pDialog.setMessage("Loading products. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
@Override
protected String doInBackground(String...param) {
try {
List<NameValuePair>params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("ID_Person", noID));
String url_product_detials = "http://10.0.2.2/getDetails.php?ID_Person="+noID;
JSONObject json = jParser.makeHttpRequest(
url_product_detials, "GET", params);
Log.d("Single Person Details", json.toString());
JSONArray productObj = json
.getJSONArray(TAG_PRODUCT);
for (int i = 0; i < productObj.length(); i++) {
JSONObject person = productObj.getJSONObject(i);
String first = person.getString("First_Name_Person");
String middle = person.getString("Middle_Name_Person");
String last = person.getString("Last_Name_Person");
String al = person.getString("Alias_Person");
String gen = person.getString("Gender_Person");
String cty = person.getString("City_Birth_Person");
String dte = person.getString("Date_Birth_Person");
String mth = person.getString("Month_Birth_Person");
String yr = person.getString("Year_Birth_Person");
firstname.setText(first);
middlename.setText(middle);
lastname.setText(last);
alias.setText(al);
gender.setText(gen);
city.setText(cty);
date.setText(dte);
month.setText(mth);
year.setText(yr);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog once got all details
pDialog.dismiss();
}
}
}
這裏是我的logcat錯誤

請人幫助我..
您正在從後臺線程（'doInBackground'方法）更新UI。你應該這樣做'onPostExecute' –
@juraganerka你好你解決了這個問題 – meda
