我正在尝试使用AsyncTask，但是我的doInBackground和onPostExecute方法都给我同样的错误提示Method does not override method from its superclass。我的代码是：
public class SigninActivity extends AsyncTask{
private TextView status, result;
private Context context;
private int flag = 0;
public SigninActivity(Context context, TextView status, TextView result, int flag) {
this.context = context;
this.statusField = status;
this.roleField = result;
this.flag = flag;
}
protected void onPreExecute() {
}
@Override
protected String doInBackground(String... arg0) {
//Code
}
@Override
protected void onPostExecute(String result) {
//Code
}
您应该使用三个参数<X，Y，Z>创建AsyncTask。在这里了解更多详情
private class MyAsyncTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... params) {
// your code
}
@Override
protected void onPostExecute(String result) {
//your code
}
@Override
protected void onPreExecute() {
//your code
}
@Override
protected void onProgressUpdate(String... text) {
// your code
}
}
