java的

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

Uri photoUri = Uri.fromFile(getOutputPhotoFile());

intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);

intent.putExtra("android.intent.extras.CAMERA_FACING", 1);

startActivityForResult(intent, CAMERA_PHOTO_REQUEST_CODE);

其他/替代解决方案

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);

} catch (RuntimeException e) {

Log.e(TAG, "Camera failed to open: " + e.toString());

}

}

}

return cam;

}

在AndroidManifest.xml文件中添加这些权限
