1.首先打开手机，找到手机上的主题商店，如图所示。

2.进入到主题商店后，在主页上找到左下角的主题，点击选择主题。
/iknow-pic.cdn.bcebos.com/3c6d55fbb2fb43162c29a6c32da4462309f7d351"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/3c6d55fbb2fb43162c29a6c32da4462309f7d351?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="

3.然后在上方找到排行，点击排行进入到新页面。

4.此时我们可以看到这里分了新品榜、付费榜、免费榜，这里我们选择免费榜为例。

5.在免费榜里找到喜欢的主题后，点击下方的下载，将主题下载到我们手机。
