无法关闭 Activity 内的 progressDialog

Question

抱歉，我知道这个问题已经被问过好几次并且有很多答案，但是 none 解决了我的问题。我正在调用 Web 服务并显示对话框，它工作正常。但我无法关闭 progressDialog。虽然同样的方法在 fragment 中起作用，但这次我在 Activity 中使用它。请指出我哪里出错了。

    public void signupServiceResponse(String phNum,String password){
    progressDialog = createProgressDialog(this, false);
    //progressDialog.show();
    final ContentServiceCall request = ServiceGenerator.createService(ContentServiceCall.class, "Empty");
    final Call<UserServiceResponse> call = request.signUp(Constants.WS_VERSION,Constants.LOCAL_EN,Constants.PLATFORM, phNum,password);

    call.enqueue(new Callback<UserServiceResponse>() {
        @Override
        public void onResponse(Call<UserServiceResponse> call, final Response<UserServiceResponse> response) {
            if(response!=null && response.isSuccessful())
            {
                if(response.body()!=null && response.body().getResponse()!=null)
                {
                    if(response.body().getResponse().getResponseCode()== Constants.RESPONSE_CODE_SUCCESS) {

                        if(response.body().getUser() != null && response.body().getUserSubscription()!= null && response.body().getUserSubscription() !=null) {

                            userEntity = response.body().getUser();
                            userProfileEntity = response.body().getUserProfile();
                            userSubscriptionEntity = response.body().getUserSubscription();
                            //insert in user table
                            int tableCode = 1; //table code 1 for user table
                            dbHelper.insertUserRegistration(userEntity, userProfileEntity, userSubscriptionEntity, tableCode);
                            dbHelper.close();
                            progressDialog.dismiss();
                            Intent i = new Intent(RegistrationActivity.this, ActivateAccountActivity.class);
                            startActivity(i);
                        }

                    } else if((response.body().getResponse().getResponseCode()== Constants.USERAlREADYEXIST_RESPONSE_CODE_SUCCESS)) {
                        // in case user data is cleared or app is reinstalled
                        boolean userCount = dbHelper.getUserCount();
                        if (userCount) {
                            Intent i = new Intent(RegistrationActivity.this, MainActivity.class);
                            startActivity(i);

                        } else if(!userCount){
                            // if user exist and data is cleared
                            userEntity = response.body().getUser();
                            userProfileEntity = response.body().getUserProfile();
                            userSubscriptionEntity = response.body().getUserSubscription();
                            int tableCode = 1;
                            dbHelper.insertUserRegistration(userEntity, userProfileEntity, userSubscriptionEntity, tableCode);
                            dbHelper.close();
                        }

                    } else if((response.body().getResponse().getResponseCode()== Constants.RESPONSE_CODE_PASSWORD_INCORRECT)){
                        Toast.makeText(RegistrationActivity.this,"Password incorrect",Toast.LENGTH_LONG).show();
                        btnForgetPassword.setVisibility(View.VISIBLE);
                        progressDialog.dismiss();
                    }

                    else {
                    }
                }
                else {
                    // leave it
                }
            }
            else
            {
                // Display proper message
                //Toast.makeText(getActivity(),getString(R.string.error_webservice_response),Toast.LENGTH_LONG).show();
            }
            progressDialog.dismiss();
        }

        @Override
        public void onFailure(Call<UserServiceResponse> call, Throwable t) {

            Log.e("Fail", "Failure");
            Log.e("ERROR", t.getMessage());
                progressDialog.dismiss();
              Toast.makeText(RegistrationActivity.this,getString(R.string.error_internet_connectivity),Toast.LENGTH_LONG).show();
        }
    });
}

public ProgressDialog createProgressDialog(Context mContext, Boolean cancelable) {
    final ProgressDialog dialog = new ProgressDialog(mContext);
    try {
        dialog.show();
    } catch (WindowManager.BadTokenException e) {

    }
    dialog.setCancelable(cancelable);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    dialog.setContentView(R.layout.dialog);

    return dialog;
}

Answer 1

你必须这样检查/写。

if(progressDialog!=null && progressDialog.isshowing){

   progressDialog.dismiss();

}

我正在使用并且它正在工作。

Answer 2

将您的 dialog 设为全局变量并在 onCreate() 中对其进行初始化（如果您在 Activity 中）。

dialog = new ProgressDialog(mContext);

添加这个方法。

public ProgressDialog dismiss() {
    if(dialog != null) {
        dialog.dismiss();
    }
}

最后，不要调用 progressDialog.dismiss()，只需调用 dismiss()。
