在
onPreExecute()其UI线程而非后台线程中获取值。
private class MyAsync extends AsyncTask<Void, Void, Void> { String firstname,lastname; @Override protected void onPreExecute() { super.onPreExecute(); table_layout.removeAllViews(); PD = new ProgressDialog(MainActivity.this); PD.setTitle("Please Wait.."); PD.setMessage("Loading..."); PD.setCancelable(false); // get values here its UI thread firstname = firstname_et.getText().toString(); lastname = lastname_et.getText().toString(); PD.show(); } @Override protected Void doInBackground(Void... params) {// **String firstname = firstname_et.getText().toString();// String lastname = lastname_et.getText().toString();** // inserting data sqlcon.open(); sqlcon.insertData(firstname, lastname); // BuildTable(); return null; } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); BuildTable(); PD.dismiss(); } }
