前言
???????在項(xiàng)目研發(fā)中，相信大家都遇到過給用戶增加頭像照片的需求。
???????隨著手機(jī)版本的不斷更新，android 8、android 9、android 10、android 12、android 13、鴻蒙系統(tǒng)等等；遇到這個功能需求，大家肯定會想，“這還不好寫？ 之前就已經(jīng)寫過了?！?/code> 把老項(xiàng)目跑了一遍之后發(fā)現(xiàn)無法運(yùn)行。要不大多數(shù)就會出現(xiàn)奔潰的情況！
???????這也就遇到常見的 高版本適配情況，以及針對不同版本該如何處理？
???????碰到這種情況也不要慌張，博主將為大家推出兩篇熱乎連載篇。從兩個不同開發(fā)場景下，來給大家分享兩篇文章，來更加詳細(xì)的了解該如何去實(shí)現(xiàn)？【特此來記錄】
???????本篇將為大家詳細(xì)講解如何調(diào)用攝像頭拍照 & 選擇相冊，并裁剪圖片。
效果
實(shí)測android 8、android 9、android 11、android 13、鴻蒙系統(tǒng)均有效；
手機(jī)機(jī)型分別為OPPO、華為、VIVO手機(jī)。
對于效果演示，將單獨(dú)拿出兩個來舉例：
- VIVO android 13
- 華為 鴻蒙系統(tǒng)2.0.1
| vivo | 華為 |
|---|---|
 |
 |
功能
- 動態(tài)申請拍照，讀，寫權(quán)限
- 自定義彈出框
- 調(diào)用系統(tǒng)相機(jī)拍照
3.1 調(diào)用系統(tǒng)相機(jī)申請拍照權(quán)限回調(diào)
3.2 拍照完成回調(diào) - 自動獲取sdk權(quán)限
4.1 訪問相冊完成回調(diào)
