当数据无效时，对话框如何保持停止或禁用

Question

我在对话框中创建一个表单。

我使用验证表单来防止数据为空时

这是我的对话

new AlertDialog.Builder(this)

                .setTitle(R.string.add_title)
                .setView(addView)

                                        new DialogInterface.OnClickListener() {
                                            public void onClick(DialogInterface dialog,
                                                    int whichButton) {

                                                String code = wrapper.getCode();

                                                String tglB = wrapper.getTglB();
                                                String userId = wrapper.getUser();
                                                new ProcessSend().execute(code, alamat, batas, lat, lon, luas, tglA, tglB, userId);
                                                //saveContact(code);
                                            }

                            })

                    .setNegativeButton(R.string.batal,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,

                                    // stop the gps when cancel
                                    lman.removeUpdates(locaListener);
                                }
                            }).show();

                            }
                        })

                .setNegativeButton(R.string.cancel,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                // stop the gps when cancel
                                lman.removeUpdates(locaListener);
                            }
                        }).show();

这是验证

if (wrapper.getCode().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Code belum terisi");return;}
                                else if (wrapper.getAlamat().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Alamat belum terisi");return;}
                                else if (wrapper.getBatas().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Informasi batas belum terisi");return;}
                                else if (wrapper.getLat().equals("Unknown")) {CUtilities.showAlert(MainPetakTetap.this, "Latitude belum terdeteksi");return;}
                                else if (wrapper.getLon().equals("Unknown")) {CUtilities.showAlert(MainPetakTetap.this, "Longitude belum terdeteksi");return;}
                                else if (wrapper.getLuas().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Luas belum terisi");return;}
                                else if (wrapper.getTglA().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Tanggal Awal belum terisi");return;}
                                else if (wrapper.getTglB().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "Tanggal Akhir belum terisi");return;}
                                else if (wrapper.getUser().length()==0) {CUtilities.showAlert(MainPetakTetap.this, "User Id belum terisi");return;}

我尝试使用此代码并验证工作，但对话框已解除。

我尝试在验证中删除return;，但数据直接处理而不进行验证。

我希望保持对话框直到验证数据。怎么做？

请我真的需要帮助

以下是我在保留验证对话框方面所做的工作

table_array=new String[numOfTables+1];
    for(int i=1; i < numOfTables+1; i++)
    {
        table_array[0]="Select";
        table_array[i]=String.valueOf(i);
    }

    // populate spinner
    spinner=new Spinner(context);
    spinner.setAdapter( new   ArrayAdapter(context,android.R.layout.simple_dropdown_item_1line, table_array));

    final AlertDialog d = new AlertDialog.Builder(context)
    .setView(spinner)
    .setTitle("Select table number")
    .setPositiveButton(android.R.string.ok,
            new Dialog.OnClickListener() {
                @Override
                public void onClick(DialogInterface d, int which) {

                }
            })
    .setNegativeButton(android.R.string.cancel, null)
    .create();

    d.setOnShowListener(new DialogInterface.OnShowListener() {

        @Override
        public void onShow(DialogInterface dialog) {

            Button b = d.getButton(AlertDialog.BUTTON_POSITIVE);
            b.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View view) {

                    if(!spinner.getSelectedItem().toString().equals("Select"))
                        {
                               d.dismiss();


                        }
                        else
                            {
                                Toast.makeText(context, "Please select the table number", 0).show();
                            }
                }
            });
        }
    });


    d.show();
