android中调用手机拍照和系统图库选择

真正能用 c# 摄像头 控制 截屏 拍照 等 代码 ，本人亲测可以用，不会报错。基本的功能都有

ionic 通过项目需求拍照，从照片库中选择照片，预览照片，全部写好，代码拿来直接用就可以。

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.R

本人亲测，可以直接运行，完全免费，非常适合学习的好例子，自己写的，欢迎下载

点击网页上的元素调用Android相机拍照或选择图片,并将图片显示在元素上

封装了一个DLL，源码在项目工程里，调用非常简单方便 msxt = new mSheXiangTou(pictureBox1); List temp = null; if ((temp = msxt.GetVideoDevicesNameList) != null) { foreach (string str in temp) { comboBox1.Items.Add(str); } comboBox1.SelectedIndex = 0; } Open.Click += new EventHandler(Open_Click); Close.Click += new EventHandler(msxt.Close_Click); LuXiang.Click += new EventHandler(msxt.LuXiang_Click); Stop.Click += new EventHandler(msxt.TingZhi_Click); PaiZhao.Click += new EventHandler(msxt.PaiZhao_Click); FormClosing += new FormClosingEventHandler(msxt.Form_FormClosing);
