我无法将Bitmap设置为我在其中一个布局中的ParseImageView。我也无法将Bitmap作为ParseFile保存到ParseDB，我相信这是因为在OnActivityResult（）上没有正确返回数据;
在用户选择图片并裁剪/保存后，是否有人知道我是否正确检索位图数据？
public class UserActivity extends Fragment implements OnClickListener {
Context context;
public ParseImageView ivProfilePic;
private TextView tvUserName, tvBio, tvTagLine;

Bundle savedInstanceState) {

// We have different layouts, and in one of them this
// fragment's containing frame doesn't exist. The fragment
// may still be created from its saved state, but there is
// no reason to try to create its view hierarchy because it
// won't be displayed. Note this is not needed -- we could
// just run the code below, where we would create and return
// the view hierarchy; it would just never be used.
return null;
}
// Inflate the layout for this fragment

保存位图以解析为文件上传...
将文件字节或位图的字节输入byteArray并将数据包装在POST的主体中进行解析。
然后，使用名称＆amp;来自解析文件上载的响应中包含的URL，以将指针/关系作为另一个类中的元素。当您想要将位图加载到视图时，可以使用与URL的关系来提供处理照片加载的某个框架。
示例：
final Uri uri = Uri.parse(arg);
final BitmapFactory.Options options = new BitmapFactory.Options();
Runnable myrun = new Runnable() {
public void run() {
options.inJustDecodeBounds = true;
try {
BitmapFactory.decodeStream(
getContentResolver().openInputStream(uri),null,options);
