Here is fragment :

package space.levan.myclass.fragment;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

/**

 */
public class LessonFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
                         @Nullable Bundle savedInstanceState) {
    TextView text = new TextView(container.getContext());
    text.setText("(╯°Д°)╯︵┴┴");
    text.setGravity(Gravity.CENTER);

    return text;
    }
}

Answer 1

You just need to add a ListView in the LessonFragment.

Follow these steps:

1. Create a layout file with a listview.

2. Inflate this layout in onCreateView method of LessonFragment and find this listview.

3. now, set an adapter for this listview, with the data you want.(hoping you know how to set an adapter)

   And now you have a listview in each tab.

    public class LessonFragment extends Fragment { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Bundle args = getArguments(); } @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View rootView = inflater.inflate( R.layout.fragment_lesson, container, false); mListView = (ListView) rootView.findViewById(R.id.listview); //create an adapter //set the above adapter to the listview return rootView; } }
