Android – Unable to resolve the symbol of Fragments

 android:id="@+id/list"
 android:layout_weight="1"
 android:layout_width="0dp"
 android:layout_height="match_parent" />

package com.example.myapp5;

import android.app.Fragment;

import android.app.Fragment;
import android.os.Bundle;
import android.view.View;

public class ArticleListFragment extends Fragment {

 @Override
 public void onCreate(Bundle savedInstanceState) {


 }

}

When I try to declare the fragment in XML, why do I get this error?

 android:id="@+id/list"
 android:layout_weight="1"
 android:layout_width="0dp"
 android:layout_height="match_parent" />

“Unable to resolve symbol: ArticleListFragment”??

Code file name ArticleListFragment.java

package com.example.myapp5;

import android.app.Fragment;

import android.app.Fragment;
import android.os.Bundle;
import android.view.View;

public class ArticleListFragment extends Fragment {

 @Override
 public void onCreate(Bundle savedInstanceState) {


 }

}

I don’t know if this fully answers your question, but it sounds like it’s not set up correctly. I have included an example which should illustrate the File Explorer when running Android Studio What it should look like (it still looks similar to this in Eclipse).

Now, you need to make sure that everything in android:name is here, but for your package.< /p>
