Android开发之拍照功能实现（附源码）

SurfaceView预览Camera，拍照demo),详见博客:http://blog.csdn.net/yanzi1225627/article/details/33028041

android调用camera时，可以自己写一个activity，赋上相关参数，打开前camera就可以了；需要申请的permission，在AndroidManifest.xml中添加：主要功能，打开前camera private Camera openFrontFacingCameraGingerbread() { int cameraCount = 0; Camera cam = null; Camera.CameraInfo cameraInfo = new Camera.CameraInfo(); cameraCount = Camera.getNumberOfCameras(); for (int camIdx = 0; camIdx < cameraCount; camIdx++) { Camera.getCameraInfo(camIdx, cameraInfo); if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) { try { cam = Camera.open(camIdx); mCurrentCamIndex = camIdx; } catch (RuntimeException e) { Log.e(TAG, "Camera failed to open: " + e.getLocalizedMessage()); } } } return cam; } 根据打开时的横竖屏方向来调整preview角度 //根据横竖屏自动调节preview方向，Starting from API level 14, this method can be called when preview is active. private static void setCameraDisplayOrientation(Activity activity,int cameraId, Camera camera) { Camera.CameraInfo info = new Camera.CameraInfo(); Camera.getCameraInfo(cameraId, info); int rotation = activity.getWindowManager().getDefaultDisplay().getRotation(); //degrees the angle that the picture will be rotated clockwise. Valid values are 0, 90, 180, and 270. //The starting position is 0 (landscape). int degrees = 0; switch (rotation) { case Surface.ROTATION_0: degrees = 0; break; case Surface.ROTATION_90: degrees = 90; break; case Surface.ROTATION_180: degrees = 180; break; case Surface.ROTATION_270: degrees = 270; break; } int result; if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) { result = (info.orientation + degrees) % 360; result = (360 - result) % 360; // compensate the mirror } else { // back-facing result = (info.orientation - degrees + 360) % 360; } camera.setDisplayOrientation(result); }
