1、首先，打开微信，进入“我的”页面，在页面下找到“设置”
/iknow-pic.cdn.bcebos.com/6d81800a19d8bc3e8abf576b8c8ba61ea9d345df"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/6d81800a19d8bc3e8abf576b8c8ba61ea9d345df?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="

2、然后进入设置页面中，找到“聊天”，进入聊天设置页面
/iknow-pic.cdn.bcebos.com/b21bb051f8198618acc7be2544ed2e738ad4e68b"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b21bb051f8198618acc7be2544ed2e738ad4e68b?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/b21bb051f8198618acc7be2544ed2e738ad4e68b"/>
3、在聊天的设置中找到聊天背景图，之后就可以看到好几个选项了
/iknow-pic.cdn.bcebos.com/3801213fb80e7bec59755240212eb9389a506be7"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/3801213fb80e7bec59755240212eb9389a506be7?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/3801213fb80e7bec59755240212eb9389a506be7"/>
4、在这些选项中，同差第一个选项中是默认的空白图片和一些纯色图片背景
/iknow-pic.cdn.bcebos.com/279759ee3d6d55fb716e278763224f4a21a4dde3"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/279759ee3d6d55fb716e278763224f4a21a4dde3?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/279759ee3d6d55fb716e278763224f4a21a4dde3"/>
5、在各种纯色图片选项中选择第一个白色图片背景，确定就可以了
/iknow-pic.cdn.bcebos.com/908fa0ec08fa513de77b3b7f336d55fbb3fbd9ba"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/908fa0ec08fa513de77b3b7f336d55fbb3fbd9ba?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/908fa0ec08fa513de77b3b7f336d55fbb3fbd9ba"/>
6、之后会退回到以下页面，在页面中最后一项，将选择的背景图应用到全部好友中，最后按确定就可以了
/iknow-pic.cdn.bcebos.com/bd315c6034a85edfa792ae8247540923dd547570"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/bd315c6034a85edfa792ae8247540923dd547570?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/bd315c6034a85edfa792ae8247540923dd547570"/>
7、然后再返回到聊天背景中查看，页面就会恢复成原始的空白界面
/iknow-pic.cdn.bcebos.com/4b90f603738da977ad17d68abe51f8198618e353"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/4b90f603738da977ad17d68abe51f8198618e353?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/4b90f603738da977ad17d68abe51f8198618e353"/>
