Activity 已泄露窗口 - 自定义对话框

Question

我正在尝试在 Activity 中显示自定义对话框，但出现此错误。我知道为什么here 和here 会出现此错误，并且也知道它的解决方案。但问题是我在我的代码中找不到问题。我花了很多时间在没有运气的情况下找到错误。 我在按钮单击时调用了以下方法

public void changePassword(View view){
    DialogChangePassword dialogChangePassword = new DialogChangePassword(ActivityMyAccount.this);
    dialogChangePassword.show();
    Window window = dialogChangePassword.getWindow();
    window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
}

我在此处显示对话框，而 Activity 应该存在。我的问题；

1. 我无法在此处关闭对话框，我在 Dialog 类中将其关闭。
2. 我没有完成活动。如果因为活动结束而发生错误，为什么会结束？
3. 如果错误不是因为完成活动，那么为什么会出现此错误？
4. 我有一个NetworkOperation 要在 Dialog 类中执行，它与它有什么关系吗？

这是我的 Dialog 类

public class DialogChangePassword extends Dialog {
    Context context;
    Button confirm, cancel;

    CustomEditText edtOldPwd, edtNewPwd, edtConfirmNewPwd;

    ProgressDialog progressDialog;

    String PASSWORD_INCORRECT_MESSAGE = "Old password is incorrect.";

    public DialogChangePassword(Context context) {
        super(context);
        this.context = context;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.dialog_change_password);

        if(progressDialog != null)
            progressDialog = null;

        progressDialog = new ProgressDialog(context);
        progressDialog.setTitle("Please wait...");
        progressDialog.setMessage("Updating Password.");
        progressDialog.show();


        confirm = (Button) findViewById(R.id.btnChangePassword);
        cancel = (Button) findViewById(R.id.btnCancel);

        edtOldPwd = (CustomEditText) findViewById(R.id.edtOldPassword);
        edtNewPwd = (CustomEditText) findViewById(R.id.edtNewPassword);
        edtConfirmNewPwd = (CustomEditText) findViewById(R.id.edtConfirmNewPassword);

        edtConfirmNewPwd.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {
                if (!edtNewPwd.getText().toString().equals(edtConfirmNewPwd.getText().toString()))
                    edtConfirmNewPwd.setError("Password doesn't match");
            }
        });

        confirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!edtNewPwd.getText().toString().equals(edtConfirmNewPwd.getText().toString())) {
                    Toast.makeText(context, "Password doesn't match",         Toast.LENGTH_SHORT).show();
                    progressDialog.cancel();
                    return;
                }
                HashMap<String, String> params = new HashMap<>();
                params.put("email", Utility.classUser.getEmailId());
                params.put("password", edtOldPwd.getText().toString());
                params.put("newPassword", edtNewPwd.getText().toString());
                new NetworkOperation().execute(params);
            }
        });
        cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }

    private class NetworkOperation extends AsyncTask<HashMap<String,String>, Void, String> {
        @Override
        protected String doInBackground(HashMap<String, String>... params) {
            try {
                ClassAPIRoutes routes = ClassAPIRoutes.initializeRoutes();
                return routes.editUserPassword(params[0]);
            } catch (final IOException e) {
                e.printStackTrace();
                getOwnerActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(context, e.toString(), Toast.LENGTH_SHORT).show();
                    }
                });
                return "error";
            }
        }

        @Override
        protected void onPostExecute(String s) {
            super.onPostExecute(s);
            progressDialog.cancel();
            dismiss();
            if(!s.equals("error")){
                JSONObject jsonObject;
                try {
                    jsonObject = new JSONObject(s);
                    if (jsonObject.get("success").toString().equals("true")) {
                        Toast.makeText(context, "Password successfully changed.", Toast.LENGTH_SHORT).show();
                        dismiss();
                    } else if (jsonObject.get("success").toString().equals("false")) {
                        if (jsonObject.get("message").toString().equals(PASSWORD_INCORRECT_MESSAGE)) {
                            Toast.makeText(context, PASSWORD_INCORRECT_MESSAGE, Toast.LENGTH_SHORT).show();
                            resetFields();
                        }
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                    Toast.makeText(getContext(), s, Toast.LENGTH_SHORT).show();
                }
            }

        }
    }

    private void resetFields(){
        edtOldPwd.setText("");
        edtNewPwd.setText("");
        edtConfirmNewPwd.setText("");
    }

}

我已经从onCreate(...) 中删除了显示进度对话框，并将其放在OnPreExecute(...) 内的Async 类中，它工作正常
