資源簡介

而本博文將通過實例實現自定義Camera的功效。具體功能如下： 1.實現自定義Camera拍照； 2.實現前后置攝像頭的切換； 3.實現Camera拍照后圖片縮小顯示以及正常預覽； 4.實現Camera拍照后圖片保存； 在具體實現代碼之前，我們先來了解一下Android api對實現自定義Camera的介紹。 根據api的介紹，對于Camera應用可以簡單總結以下幾個步驟。 1.檢查Camera是否存在，并在AndroidManifest.xml中賦予相關的權限； 2.創建一個繼承于SurfaceView并實現SurfaceHolder接口的Camera Preview類； 3.在2的基礎上新建一個Camera Preview布局文件； 4.設置一個拍照的監聽事件，例如單擊按鈕事件等； 5.實現拍照，并保存拍照后的圖片到設備； 6.釋放Camera，以方便其他應用可以使用。
