android调用照相机拍照获取照片并…

1.调用系统的照相机程序
Intent intent = newIntent(MediaStore.ACTION_IMAGE_CAPTURE);
 startActivityForResult(intent,TAKE_PHOTO_WITH_DATA);

2.在onActivityResult中处理返回的data
final Bitmap photo = data.getParcelableExtra("data");
如果不需要做剪切处理就可以直接使用图片了，比如输出到ImageView上
imageView.setImageBitmap(photo);
如果需要做剪切处理，就继续向下执行

3.做剪切处理
    

Intent intent = newIntent("com.Android.camera.action.CROP");
        intent.setType("image
