解决oppo、vivo手机从相册选择图片获取图片地址问题

打开相册

                    if (position == 0) {//打开相册Intent intent = new Intent();intent.addCategory(Intent.CATEGORY_OPENABLE);intent.setType("image/*");if (Build.VERSION.SDK_INT < 19) {intent.setAction(Intent.ACTION_GET_CONTENT);} else {intent.setAction(Intent.ACTION_OPEN_DOCUMENT);}startActivityForResult(intent, REQUEST_CODE_PICK);} else if (position == 1) {//打开相机Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//下面这句指定调用相机拍照后的照片存储的路径intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new                         File(Environment.getExternalStorageDirectory().getPath()+"/"+"table.jpg")));startActivityForResult(intent, REQUEST_CODE_CAMERA);}

选择图片后的回调

//相机相册的回调@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (requestCode == REQUEST_CODE_PICK && resultCode == RESULT_OK) {String path = GetPathFromUri.getPath(UploadSkillCertifyActivity.this, data.getData());//imgPath就是压缩后的图片String imgPath = BitmapUtil.compressImageUpload(path);} else if (requestCode == REQUEST_CODE_CAMERA && resultCode == RESULT_OK) {String cameraPath = Environment.getExternalStorageDirectory().getPath()+"/"+"table.jpg";//imgPath就是压缩后的图片String imgPath = BitmapUtil.compressImageUpload(path);}}
