如果在Java中未选中复选框，如何禁用正负按钮？

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();

Answer 1

Try Using setEnabled() and setClickable method for buttons.

here is the doc

Answer 2

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.

Answer 3

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
