在警报对话框生成器中禁用肯定按钮

Question

我已经创建了一个警报对话框构建器，其中正在显示一个表单的对话，我的积极按钮名称是提交，我希望按钮被禁用，除非表单中的所有字段都被填满。下面是我的代码，任何人可以帮助我在这方面的工作。谢谢

        alertDialogBuilder.setPositiveButton("SAVE", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    nameInput1 = data_txt1.getText().toString();
                    nameInput2 = data_txt2.getText().toString();
                    nameInput3 = data_txt3.getText().toString();
                    nameInput4 = data_txt4.getText().toString();
                    nameInput5 = data_txt5.getText().toString();

                    nameInput6 = auto_txt1.getText().toString();
                    nameInput7 = auto_txt2.getText().toString();
                    nameInput8 = auto_txt3.getText().toString();
                    nameInput9 = auto_txt4.getText().toString();
                    nameInput10 = auto_txt5.getText().toString();
                    nameInput11 = auto_txt6.getText().toString();
                    nameInput12 = auto_txt7.getText().toString();
                    nameInput13 = auto_txt8.getText().toString();
                    nameInput14 = auto_txt9.getText().toString();

                    nameInput15 = data_txt6.getText().toString();
                    nameInput16 = data_txt7.getText().toString();



                        Call<Void> completeQuestionnaireCall = spreadsheetWebService.completeQuestionnaire(nameInput1, nameInput2, nameInput3, nameInput4, nameInput5, nameInput6, nameInput7, nameInput8, nameInput9, nameInput10, nameInput11, nameInput12, nameInput13, nameInput14, nameInput15, nameInput16);
                        completeQuestionnaireCall.enqueue(callCallback);
                        dialog.dismiss();

                    }



                }
            });

    alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();

        }
    });

    alertDialogBuilder.show();
}

您还可以通过以下操作：

new AlertDialog.Builder(this)
    .setMessage("This may take a while")
    .setPositiveButton("OK", new android.content.DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
         ((AlertDialog)dialog).getButton(which).setVisibility(View.INVISIBLE);
         // the rest of your stuff
    }
})
    .show();
