Question

我已经实现了PopupWindow登录，当我按下Login按钮时，我正在使用setError函数验证用户名和密码的edittext。但是App崩溃，异常＆＃34; android.view.WindowManager $ BadTokenException：无法添加窗口＆＃34;

任何解决方案？

Activity activity;
PopupWindow popupLogin;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    activity = this;

}


   @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            switch (item.getItemId()) {
                case R.id.menu_login:
                    if (popupLogin == null || !popupLogin.isShowing())
                        showLogin();

                    return true;

                default:
                    return super.onOptionsItemSelected(item);
            }
        }


    private void showLogin() {
            LayoutInflater inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View popupView = inflater.inflate(R.layout.dialog_login,
                    null);

            popupLogin = new PopupWindow(
                    popupView, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
            Display display = activity.getWindowManager().getDefaultDisplay();
            popupLogin.setFocusable(true);
            popupLogin.update();
            Point size = new Point();
            display.getSize(size);


            Rect rectangle = new Rect();
            Window window = activity.getWindow();
            window.getDecorView().getWindowVisibleDisplayFrame(rectangle);
            int topbar = rectangle.top + toolbar.getHeight();
            edtBroker = (EditText) popupView.findViewById(R.id.edit_broker_code);
            edtUname = (EditText) popupView.findViewById(R.id.edit_username);
            edtPwd = (EditText) popupView.findViewById(R.id.edit_pwd);
            // popupLogin.setAnimationStyle(R.style.PopupWindowAnimation);
            popupView.findViewById(R.id.btn_cancel).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    popupLogin.dismiss();

                }
            });
            popupView.findViewById(R.id.btn_login).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {


                    if (validate()) {
                        popupLogin.dismiss();
                        doLogin(edtBroker.getText().toString().trim(), edtUname.getText().toString().trim(), edtPwd.getText().toString().trim());
                    }
                }
            });

            popupLogin.showAtLocation(toolbar, Gravity.NO_GRAVITY, 0, topbar);


        }


 private boolean validate() {

        if (TextUtils.isEmpty(edtBroker.getText().toString())) {
            edtBroker.setError(getString(R.string.plz_broker_code));//getting exception here
            edtBroker.requestFocus();
            return false;
        }
        if (TextUtils.isEmpty(edtUname.getText().toString())) {
            edtUname.setError(getString(R.string.plz_enter_username));
            edtUname.requestFocus();
            return false;
        }
        if (TextUtils.isEmpty(edtPwd.getText().toString())) {
            edtPwd.setError(getString(R.string.plz_enter_password));
            edtPwd.requestFocus();
            return false;
        }
        if (!NetworkStatus.getConnectivityStatus(activity)) {
            CommonUtility.showAlertToast(activity, getString(R.string.check_internet), "");
            return false;
        }

        return true;
    }

Answer 1

我认为您在活动中使用了applicationContext()。

而不是getApplicationContext()，只需使用ActivityName.this。

我认为它会解决您的问题。
