【Android代码片段04】调用前置摄像头

onCreate方法中

if(null == myCamera) {// 打开前置摄像头int cameraCount = 0;  @SuppressWarnings("unused")Camera.CameraInfo cameraInfo = new Camera.CameraInfo();  cameraCount = Camera.getNumberOfCameras(); // get cameras number  for ( int camIdx = 0; camIdx < cameraCount;camIdx++ ) {  Camera.getCameraInfo( camIdx, cameraInfo ); // get camerainfo  if ( cameraInfo.facing ==Camera.CameraInfo.CAMERA_FACING_FRONT )                                   { //代表摄像头的方位，目前有定义值两个分别为CAMERA_FACING_FRONT前置和CAMERA_FACING_BACK后置  try {              myCamera = Camera.open( camIdx );  } catch (RuntimeException e) {  e.printStackTrace();  break;}}  }

按钮的点击事件中：

  myCamera.unlock();if (null == mediarecorder) {mediarecorder = new MediaRecorder();// 创建mediarecorder对象 }       mediarecorder.setCamera(myCamera);// 设置录制视频源为Camera(相机) mediarecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

​或将上述代码都放在按钮的点击事件中。
