我想在安卓系统中保留警报对话框MutliChoicesItems中选定选项的状态？

boolean[] checkedItems = new boolean[options.length]; // options为选项数组

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("选择选项")
        .setMultiChoiceItems(options, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                checkedItems[which] = isChecked;
            }
        })
        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 保存选中状态的布尔数组
                // TODO: 在这里处理选中状态
            }
        })
        .setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 恢复选项的选中状态
                for (int i = 0; i < checkedItems.length; i++) {
                    checkedItems[i] = false;
                }
            }
        });

AlertDialog dialog = builder.create();
dialog.show();
