android 桌面角標(biāo)能力

小米

測(cè)試結(jié)果：支持角標(biāo)能力，最大值為9（官方數(shù)據(jù)）， （實(shí)測(cè)可以到note4 顯示為9999...mix2s 顯示為99999....）

條件：需要向狀態(tài)欄發(fā)送一條通知，進(jìn)入APP則角標(biāo)消失，抹除通知?jiǎng)t角標(biāo)也消失 ，在端內(nèi)時(shí)不顯示

首先打開(kāi)應(yīng)用通知設(shè)置頁(yè)面，在”設(shè)置-通知管理“里點(diǎn)擊應(yīng)用，查看”顯示桌面圖標(biāo)角標(biāo)“開(kāi)關(guān)是否開(kāi)啟。大部分應(yīng)用默認(rèn)是關(guān)閉狀態(tài)。

測(cè)試結(jié)果：支持角標(biāo)能力

條件 EMUI4.1 及以上及以上手機(jī) 打開(kāi)通知和角標(biāo) 選擇顯示為數(shù)字角標(biāo)

最多顯示99 超過(guò)99顯示為99+

官網(wǎng)資料需要添加 華為權(quán)限 （實(shí)測(cè)不加也能顯示） 代碼需要try處理 避免無(wú)角標(biāo)能力導(dǎo)致崩潰

結(jié)論：需要向VIVO申請(qǐng)接入“桌面圖標(biāo)角標(biāo)”，但是官方?jīng)]放開(kāi)

三星

結(jié)論：（網(wǎng)上資料）三星S9+ 以上 需和通知的方式結(jié)合才能顯示角標(biāo)，

三星 Galaxy S6 ：可直接設(shè)置。設(shè)置為0 則角標(biāo)消失

顯示數(shù)量上限不限 ，暫無(wú)其他三星手機(jī)進(jìn)行測(cè)試。

魅族

結(jié)論：官方不支持

總結(jié)

華為 小米 三星 部分原生系統(tǒng) 可以支持。 oppo vivo 魅族 暫時(shí)不支持

代碼編寫(xiě)

小米角標(biāo)代碼

這里簡(jiǎn)單備注一下，小米在進(jìn)入app內(nèi)的時(shí)候，角標(biāo)消息會(huì)清除。所以在處理小米的時(shí)候，在應(yīng)用在后臺(tái)的時(shí)候 應(yīng)該再次將角標(biāo)顯示出來(lái)。

通知的加入（TPNS）

端內(nèi)使用的是TPNS,也就是原來(lái)的信鴿，這部分代碼不具備通用性。如果你也使用的是TPNS可以進(jìn)行參考。

通知的增加和刪減

經(jīng)測(cè)試，小米在收到通知的時(shí)候，在tpns下角標(biāo)會(huì)自動(dòng)增加1，通知抹除的時(shí)候 會(huì)自動(dòng)扣除1。

華為（榮耀）在通知到來(lái)時(shí)，角標(biāo)不會(huì)增加，但是通知?jiǎng)h除的時(shí)候則會(huì)減去1.如果 在通知?jiǎng)h除的時(shí)候 進(jìn)行角標(biāo)設(shè)置。則可能會(huì)發(fā)生，刪除一個(gè)扣2個(gè)的可能性。則這里進(jìn)行一個(gè)延遲操作?；究梢越鉀Q這個(gè)問(wèn)題。如果有其他好的方法請(qǐng)留言。

代碼相關(guān)

TPNS里面消息的接收在XGPushBaseReceiver 類里，繼承XGPushBaseReceiver，

onNotificationShowedResult --消息到來(lái)展現(xiàn)

onNotificationClickedResult --消息劃掉或者點(diǎn)擊回調(diào)
