系统相机拍照剪辑问题

调用系统相机

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

// 加载路径

Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"temp.jpg"));

// 指定存储路径，这样就可以保存原图了

 intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);

startActivityForResult(intent, Constant.CAMERA);

因为设置了输出路径，onActivityResult的data就获取不到数据了。
重写onActivityResult

if(requestCode == Constant.CAMERA){

        	File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg");

        	startPhotoZoom(Uri.fromFile(picture));

}

public void startPhotoZoom(Uri uri) {

		 

		 Intent intent = new Intent("com.android.camera.action.CROP");

		 intent.setDataAndType(uri, "image/*");

		 intent.putExtra("crop", "true");

		 // aspectX aspectY 是宽高的比例

		 intent.putExtra("aspectX", 1);

		 intent.putExtra("aspectY", 1);

		 // outputX, outputY 是裁剪图片宽高

		 intent.putExtra("outputX", 640);

		 intent.putExtra("outputY", 640);

		 intent.putExtra("output", Uri.fromFile(CameraFile)); //保存路径

		 intent.putExtra("outputFormat", "JPEG");// 返回格式

		 intent.putExtra("return-data", true);

		 startActivityForResult(intent, Constant.IMG_RESULTS);

	 }

重写onActivityResult，添加了

if(requestCode == Constant.IMG_RESULTS){

        	

        	try {

                // 获取输入流

                is = new FileInputStream(CameraFile);

                // 把流解析成bitmap

                Bitmap bitmap = BitmapFactory.decodeStream(is);

                // 设置图片

                img.setImageBitmap(bitmap);

            } catch (FileNotFoundException e) {

                e.printStackTrace();

            } finally {

                // 关闭流

                try {

                    is.close();

                } catch (IOException e) {

                    e.printStackTrace();

                }

            }

        }
