26.HarmonyOS App(JAVA)列表对话框

列表对话框的单选模式：

 //单选模式
//        listDialog.setSingleSelectItems(new String[]{"第1个选项","第2个选项"},1);//单选
//        listDialog.setOnSingleSelectListener(new IDialog.ClickedListener() {
//            @Override
//            public void onClick(IDialog iDialog, int i) {
//                showToast(context,"单击了第"+(i+1)+"个选项");
//            }
//        });

多选模式：

 //多选模式listDialog.setMultiSelectItems(new String[]{"第1个选项","第2个选项"},new boolean[]{false,false});//多选listDialog.setOnMultiSelectListener(new IDialog.CheckBoxClickedListener() {@Overridepublic void onClick(IDialog iDialog, int i, boolean b) {showToast(context,"单击了第"+(i+1)+"个选项");}});
