Country list dialog window is having much space in left & right.

When you click the `ccp` to select country , a dialog appears that would has country lists , Right ?
Then if we check the same with small size devices , the country name list are not properly aligned and positioned as well. there is an overlap between two item if it was in small screen device.

首先在小屏幕 Android 设备上复现通过 ccp 打开的国家选择对话框，然后定位对话框和国家列表的实现。将项目的对齐方式和间距与报告的重叠问题进行比较；完成的标准是国家名称在小屏幕上正确定位，没有多余的侧边空间或重叠。
