問題が発生しました。私の非同期タスクはうまくやっています。しかし、私のOnPostExecuteで、私はこれを手に入れました：
if (error = true) {
loginErrorMsg.setText("Incorrect username/password");
} else {
loginErrorMsg.setText("");
}
彼がまだ表示している場合error == falseでも：ユーザー名/パスワードが正しくありません...
class LoginUser extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Loading");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
email = inputEmail.getText().toString();
password = inputPassword.getText().toString();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
UserFunctions userFunction = new UserFunctions();
Log.d("Button", "Login");
JSONObject json = userFunction.loginUser(email, password);
// check for login response
try {
if (json.getString(KEY_SUCCESS) != null) {
String res = json.getString(KEY_SUCCESS);
if(Integer.parseInt(res) == 1){
// user successfully logged in
// Store user details in SQLite Database
DatabaseHandler db = new DatabaseHandler(getApplicationContext());
JSONObject json_user = json.getJSONObject("user");
// Clear all previous data in database
userFunction.logoutUser(getApplicationContext());
db.addUser(json_user.getString(KEY_NAME), json_user.getString(KEY_EMAIL), json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT));

// Close all views before launching Dashboard
