SurfaceView局部拍照-

该库大部分参考 IsseiAoki 的 SimpleCropView https://github.com/IsseiAoki/SimpleCropView
实现了在相机的预览界面指定一个区域的大小，形状和位置，只拍摄该指定区域里的图像
支持 API Level 10 and above.

使用方法：

在工程和 module 里的 build.gradle 分别添加

allprojects {        repositories {            ...            maven { url 'https://jitpack.io' }        }    }dependencies {            compile 'com.github.CGmaybe10:FocusSurfaceView:v1.0.1'    }

<com.cymaybe.foucsurfaceview.FocusSurfaceView        android:id="@+id/preview_sv"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="@android:color/transparent"        android:visibility="visible"        app:focus_crop_height="267dp"        app:focus_crop_width="200dp"        app:focus_frame_can_change="true"        app:focus_frame_color="@android:color/holo_green_dark"        app:focus_frame_stroke_weight="1dp"        app:focus_guide_color="@android:color/holo_green_dark"        app:focus_guide_show_mode="not_show"        app:focus_guide_stroke_weight="1dp"        app:focus_handle_color="@android:color/holo_green_dark"        app:focus_handle_show_mode="not_show"        app:focus_handle_size="14dp"        app:focus_min_frame_size="50dp"        app:focus_mode="circle"        app:focus_overlay_color="#66000000"        app:focus_touch_padding="8dp"/>

private FocusSurfaceView previewSFV = (FocusSurfaceView) findViewById(R.id.preview_sv);mCamera.autoFocus(new Camera.AutoFocusCallback() {            @Override            public void onAutoFocus(boolean success, Camera camera) {                                 mCamera.takePicture(new Camera.ShutterCallback() {                        @Override                        public void onShutter() {                        }                    }, null, null, new Camera.PictureCallback() {                        @Override                        public void onPictureTaken(byte[] data, Camera camera) {                            Bitmap cropBitmap = previewSFV.getPicture(data);                                               }                    });                }            }        });
