使用方法
 

UploadPicture uploadPicture = new UploadPicture();
uploadPicture.setUploadCallBack(uploadCallBack);
//弹出选择图片
uploadPicture.uploadPictue(REQUEST_UPLOAD_BY_PICTURE);
//或者裁剪
uploadPicture.uploadPictueByCrop(REQUEST_UPLOAD_BY_PICTURE, 裁剪后保存的文件,裁剪框X, 裁剪框Y, 输出图片宽度, 输出图片高度);

在activity中的onActivityResult中加上
uploadPicture.onActivityResult(requestCode, resultCode, data);

最后在回调中获得文件路径
UploadCallBack uploadCallBack = new UploadCallBack() {
	@Override
	public void callback(final int requestCode, final String filePath) {
	}
}
