我正在尝试此代码。它允许图像上传为图库部分，但相机部分出错。
错误是：
java.lang.NullPointerException：尝试调用虚方法 'java.lang.Object android.os.Bundle.get（java.lang.String）'为null 对象参考`
代码：
public class MyProfile extends Fragment implements View.OnClickListener {
//This is the unique id which represents the id has been selected
private static final int RESULT_LOAD_IMAGE = 1;
ImageView profilePic;
Button buttonToUpload;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_my_profile, container, false);
buttonToUpload = (Button) rootView.findViewById(R.id.upload_button);
profilePic = (ImageView) rootView.findViewById(R.id.profile);
buttonToUpload.setOnClickListener(this);
// Inflate the layout for this fragment
return rootView;
}
@Override
public void onClick(View v) {
CharSequence choice[] = {"Gallery", "Camera"};
AlertDialog.Builder alertDialog = new AlertDialog.Builder(getActivity());
alertDialog.setTitle("Choose").
setItems(choice, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if(which == 0){
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
//When the user selects a picture the result of which image is selected by the user is given by startActiviytForResult
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}else {
//If User chooses to upload photo through camera
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, RESULT_LOAD_IMAGE);
}
}
});
alertDialog.show();
}
