How to disable positive and negative button if the checkbox is unchecked in java?

Question

I'm trying to do alert message by disable ok and cancel button if the checkbox is unchecked.

reconfirm.java:

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(reconfirm.this);
                LayoutInflater layoutInflater 
                 = (LayoutInflater)getBaseContext()
                  .getSystemService(LAYOUT_INFLATER_SERVICE);  
                View popupView = layoutInflater.inflate(R.layout.popup, null);


                alertDialogBuilder.setView(popupView);

                CheckBox check= (CheckBox)findViewById(R.id.checkBox1);  

            if (check.isChecked() ) {

                    AlertDialog dialog = null;
                    ((AlertDialog)dialog).getButton(DialogInterface.BUTTON_POSITIVE).setVisibility(View.INVISIBLE);
                }




                alertDialogBuilder.setPositiveButton("OK",new DialogInterface.OnClickListener() {
                      public void onClick(DialogInterface dialog, int id) {

                          Intent intObj = new Intent(getApplicationContext(),
                                agree.class);
                        startActivity(intObj);
                      }
                  });


                alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int id) {


                     Intent intObj = new Intent(getApplicationContext(),
                                IntentExampleActivity.class);
                            startActivity(intObj);


                  }

                  });

                AlertDialog alertDialog = alertDialogBuilder.create();

                // show it
                alertDialog.show();

@deniz When I clicked on checkbox "I agre...." the OK and CANCEL will enable. Before that the buttons disable. — user3714182, Aug 22 '14 at 10:06

Try following code snippets. Hope you get some idea from this :)

if (check.isChecked()) {
 alertDialogBuilder.getButton(Dialog.BUTTON_POSITIVE).setEnabled(false);
 alertDialogBuilder.getButton(Dialog.BUTTON_NEGATIVE).setEnabled(false);
}

where dialog is object of AlertDialog.

what is the different between using AlertDialog alertDialog = alertDialogBuilder.create(); with final AlertDialog dialog = builder.create();? – user3714182 Aug 25 '14 at 04:17
@user3714182 I have updated my answer.My intention was to tell that it is object of AlertDialog.I have just answered with reference to your code.Did it worked for u? – Harshal Benake Aug 25 '14 at 06:14

This is answered already here--How to disable / enable dialog negative positive buttons?

after dialog.show use below code

if(your_condition_true) dialog.getButton(AlertDialog.BUTTON1).setEnabled(false); //BUTTON1 is positive button
