How to set a custom adapter in case of multiple textviews per listview present in a fragment

Question

I have a listview in a fragment. I want to set those multiple textviews. So how should i set the custom adapter. I am new at android and need some help.

public class Tab1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.tab_1, container, false);

        ListView listView = (ListView)v.findViewById(R.id.listOfTasks);

//need to pass 2 string arrays.
//string[] s1;
//string[] s2; 

 ListAdapter taskAdapter = new TaskCustomAdapter(  //here.....  );
        listView.setAdapter(taskAdapter);

        listView.setOnItemClickListener(
                new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                        String task = String.valueOf(parent.getItemAtPosition(position));
                        Toast.makeText(getActivity(),task,Toast.LENGTH_SHORT).show();
                    }
                }
        );

        return v;
    }

}

this is my list view with multiples textfields.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="60dp">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="Large Text"
            android:id="@+id/task_title"
            android:layout_gravity="left|center_vertical"
            android:layout_marginLeft="20dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="Large Text"
            android:id="@+id/task_subtitle"
            android:layout_gravity="center" />


    </FrameLayout>

</LinearLayout>

And my present adapter is :

public class TaskCustomAdapter extends ArrayAdapter<String>{

    public TaskCustomAdapter(Context context,String[] tasks) {
        super(context,R.layout.taskfragment,tasks);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent){

        LayoutInflater task_inflater = LayoutInflater.from(getContext());
        View customView = task_inflater.inflate(R.layout.taskfragment,parent,false);

        String task = getItem(position);
        TextView title = (TextView)customView.findViewById(R.id.task_title);
        title.setText(task);

        return customView;
    }
}

thanks!

i m not able to pass both the string arrays to my adapter. I have searched for the same problem which is solved when i pass them from an activity but not solved when i pass them from a fragment .@ρяσѕρєяK — aman003, Jul 19 '16 at 13:22

You're on the right track! You've almost done it yourself. Just initialize all the components (TextViews or whatever) here, as you did with the one TextView already:

TextView title = (TextView)customView.findViewById(R.id.task_title);
TextView subtitle = (TextView)customView.findViewById(R.id.task_subtitle);
//etc for every one
title.setText(task);
subtitle.setText("whatever");

Simply use them like you normally would. Do consider using the ViewHolder pattern for this kind of thing, read more about it on the linked question.

EDIT:

Another thing you asked, how to pass 2 arrays, simply change the constructor like so:

private String[] subtitles; //or whatever

public TaskCustomAdapter(Context context,String[] tasks, String[] subs) {
    super(context,R.layout.taskfragment,tasks);
    subtitles = subs;
}

And now simply call the constructor with the additional parameter like:

ListAdapter taskAdapter = new TaskCustomAdapter(getActivity(), s1, s2);

Where s1 and s2 are the string arrays you want to pass. You can now use the second textView something like this:

subtitle.setText(subtitles[position]);

But how do i send these two strings[] s1 and s2 ? Adapter can have only 2 arguments which are the activity and one string only.. Please tell me how to pass both the strings to my adapter?? — aman003, Jul 19 '16 at 13:13
That's easy man, just add another array to the constructor argument and assign a local variable to that value. I'll edit my answer. @aman003 — Vucko, Jul 19 '16 at 13:56

Below code put in activity oncreate::: 

//List view reference
    ListView lv=(ListView) findViewById(R.id.listView);
//Creating the custom adapter and passing the string array data
     MainListViewCustomAdapter adapter = new MainListViewCustomAdapter(this,titleList,subtitlelist)
//Setting the adapter to listview
       lv.setAdapter(adapter);
