I'm working on a flutter project and I want to import a dart file in my main file but I don't know how to do it.
I import my dart file first import 'package:splash/Categories.dart';
and I initialized it like that final Category _category = Category();
but I have this error Try using 'as prefix' for one of the import directives, or hiding the name from all but one of the imports
Please how can I fix it. Thank you in advance
This happens when the same class is in two different files. So if you want to use a specific class in specific file we need to use aliases.
Example:
import 'package:splash/Categories.dart';
import 'package:something/Something.dart' as name;
Use classname in Something.dart as name.class_name

I currently have a imported color class from another Android Library:
import com.google.ar.sceneform.rendering.Color;
but I need to import another color class:
import android.graphics.Color;
but after typing this import, it gives me the error:
so I have to end up removing the second import and use it manually like this:
mBtnColor.setColorFilter(android.graphics.Color.parseColor(color));
is there a way I can import both classes? or maybe use the second import without typing android.graphics.Color?
Create two classes: one inherits the first Color and does nothing and is called AndroidGraphicsColor and the other one inherits the appropriate class and is called AndroidSceneFormRenderingColor. Then use them.
I created an application that uses the Room, ViewModel approach. I created subfolders to organize my code as shown in the photo:
How do I make my Main Activity recognize the code created in the subfolders? I tried invalidate caches/restart already and tried many times to rebuild the project.
There was an issue when I created my folders. I used New->Folder->Java Folder when the right process should be New->Package
You have to write an import statement for the classes to be recognized:
import com.example.laundry.data.ViewModel.CustomerViewModel
I think there are various ways to solve this problem.
Process 1.
For your Adapter import this
import com.example.laundry.adapter.CustomerListAdapter;
For your ViewModel import this
import com.example.laundry.data.ViewModel.CustomerViewModel;
Process 2
If you write down your adapter/model class name it will show some popup. From there you can select.
just like when I tried to import InfiniteScrollAdapter I got these options
Process 3
Please check if you have already import that adapter/model class with the different package names. Just delete that line and import again with alt+ enter
I want to replace the dependency of com.nineoldandroids library from my project and replace it with an android native library.
I am trying to make a project based on this http://www.tutecentral.com/android-swipe-listview/ .
However, I don't need to have support for android versions less than v11. Therefore there is no need to use this library. But I cannot find what to use in its place, while not making changes to the code itself.
The project import the classes
import com.nineoldandroids.animation.Animator;
import com.nineoldandroids.animation.AnimatorListenerAdapter;
import com.nineoldandroids.animation.ValueAnimator;
import com.nineoldandroids.view.ViewHelper;
import static com.nineoldandroids.view.ViewHelper.setAlpha;
import static com.nineoldandroids.view.ViewHelper.setTranslationX;
import static com.nineoldandroids.view.ViewPropertyAnimator.animate;
Thank you.
I had the same issue, wanted to get rid of nineoldandroids library.
As per #Selvin comment this is what you need to do:
1.) Remove all Imports
2.) Animation and ValueAnimator are available as part of the android.animation package
3.) ViewHelper doesn't really do anything that is not already available as part of each view's method.
For example:
ViewHelper.setScaleX -> view.setScaleX
ViewHelper.setY -> view.setY
ViewHelper.setAlpha -> view.setAlpha
Hope it helps.
How remove unnecessary import from package eclipse for android.
When i add some method after removing it the import statements not getting remove.
Is there a way to remove from entire application...
Instead of removing one by one.
You can use ctr + shift + o for removing unnecessary import of your class.
It is not just for removing but also used for importing the class that is not yet imported to your class.
The only way by which you import all defined packages that means
CTRL+SHIFT+O
I'm currently working on an android project, using greenDAO as ORM, and I need to make multiple requests on different tables of my database. But when I try to import multiple Properties (useful for the .where() queries) I got this error :
The import psa_gt.dao.quizz_categoriesDao.Properties collides with another import statement
My import :
import package.dao.quizz_questionsDao.Properties;
import package.dao.quizz_categoriesDao.Properties;
My queries (the second returns this error : "Quizz_categories_id_quizz cannot be resolved or is not a field") :
List<quizz_questions> list_questions = daoquestions.queryBuilder().where(Properties.Quizz_questions_id_quizz.eq(value)).list();
List<quizz_categories> list_categories = daocategories.queryBuilder().where(Properties.Quizz_categories_id_quizz.eq(value)).list();
Hope you can help me with that.
(Sorry for my bad English but there is no French support for greenDAO.)
Properties used in the code is ambiguous since compiler doesn't know whether to resolve it to package dao.quizz_questionsDao or dao.quizz_categoriesDao
Solution:
Remove the imports.
And in code use fully qualified class name. i.e.
List list_questions = daoquestions.queryBuilder().where(dao.quizz_questionsDao.Properties.Quizz_questions_id_quizz.eq(value)).list(); List list_categories = daocategories.queryBuilder().where(dao.quizz_categoriesDao.Properties.Quizz_categories_id_quizz.eq(value)).list();
