調(diào)用的方法：

  myDialog = new MyDialog(activity);
                            myDialog.setTitle("提示");
                            myDialog.setMessage("您輸入的關(guān)鍵字未查詢到信息，請重新輸入");
                            myDialog.setYesOnclickListener("確定", new MyDialog.onYesOnclickListener() {
                                @Override
                                public void onYesClick() {
                                    myDialog.dismiss();
                                }
                            });
                            myDialog.show();

這是一個調(diào)用只含有確認(rèn)鍵的方法，通過mydialog中傳的str來進(jìn)行判斷，gone或者vs:

   if (noStr != null) {
            no.setVisibility(View.VISIBLE);
            view.setVisibility(View.VISIBLE);
            no.setText(noStr);
        } else {
            no.setVisibility(View.GONE);
            view.setVisibility(View.GONE);
        }

調(diào)用倆個按鍵：

    myDialog = new MyDialog(activity);
                    myDialog.setTitle("指紋關(guān)閉確認(rèn)");
                    myDialog.setMessage("確認(rèn)關(guān)閉指紋登陸？");
                    myDialog.setYesOnclickListener("確定", new MyDialog.onYesOnclickListener() {
                        @Override
                        public void onYesClick() {
                            SharedPreferenceUtil.setInfoToShared("Z", "N");
                            myDialog.dismiss();
                        }
                    });
                    myDialog.setNoOnclickListener("取消", new MyDialog.onNoOnclickListener() {
                        @Override
                        public void onNoClick() {
                            cbFingerprint.setChecked(true);
                            myDialog.dismiss();
                        }
                    });
                    myDialog.show();
