Android應(yīng)用圖標(biāo)上的小紅點(diǎn)Badge實(shí)踐代碼

現(xiàn)在Android中有許多的應(yīng)用仿蘋(píng)果的在應(yīng)用圖標(biāo)上顯示小紅點(diǎn)。當(dāng)然有著一些手機(jī)ROM對(duì)小紅點(diǎn)的支持，比如小米，三星等。google的api是沒(méi)有提供這項(xiàng)工能的,這項(xiàng)功能一般都是廠商自己定制的,所以讓開(kāi)發(fā)者著實(shí)頭痛,我也是弄了2天,不是所有的機(jī)型都可以.以后再一點(diǎn)點(diǎn)完善吧.希望對(duì)讀文章的人,或也在受此困惑的人有點(diǎn)幫助!

效果圖:(DODO那個(gè)是我的應(yīng)用,小米miui8測(cè)試)

直接上代碼吧,代碼中有注釋:

總結(jié):

小米,三星,索尼,htc,朵唯.手中有的手機(jī)基本小紅點(diǎn)功能都是沒(méi)有問(wèn)題的.

oppo:廠商不提供此功能,只對(duì)于市面上排名前5的商用聊天提供,還說(shuō)對(duì)企業(yè)內(nèi)部的im會(huì)提供此功能,不過(guò)必須要集成oppo證書(shū).

華為:與oppo說(shuō)法一樣,但是按上面代碼測(cè)試,華為的部分機(jī)型是可以實(shí)現(xiàn)的.榮耀6和6p沒(méi)有效果.

vivo:部分手機(jī)有效果,vivo xplay5 x7 沒(méi)有效果.

至于錘子,魅族,金立等,網(wǎng)上說(shuō)是不支持此功能的,,因?yàn)闆](méi)有測(cè)試機(jī),并沒(méi)有驗(yàn)證.

樂(lè)視:有自帶效果(沒(méi)有詢(xún)問(wèn)客服,就不給人添亂了!)
