Android：无法应用 AsyncTask 的 execute() 方法。 为什么？

Question

The code:

attemptLogin.execute(editName.getText().toString(),editPassword.getText(),"");

There is an error on the above line.

The code for AsyncTask is as follows:

private class AttemptLogin extends AsyncTask<String, String, JSONObject> {

@override

There is an error on the override too.

Answer 1

Replace @override with @Override .

Also replace attemptLogin.execute(editName.getText().toString(),editPassword.getText(),""); with attemptLogin.execute(editName.getText().toString(),editPassword.getText().toString(), obj);

Note: In the third parameter, the obj should be of type "JSONObject". Please do send it as a parameter. Replace "" by JSONObject instance.
