android.widget.LinearLayout cannot be cast to android.widget.TextView (android-studio)

Question

Im Trying To paste data(from an Intent) on a customized ListView ,and then I get this error,but when I did it with an uncustomized ListView it worked properly. I understood that the problem occurs when I change :

ListAdapter theAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,timegone);

to:

 ListAdapter theAdapter=new ArrayAdapter<String>(this,R.layout.row_layout,timegone);

But I dont get why it doesnt work!

Here below I added the row_layout.xml file which Causes the app crash.

Thats how it works :

public class Shifts extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

  setContentView(R.layout.shifts);
    Intent MyIntent=getIntent();
    String timepass=MyIntent.getExtras().getString("time");

    ListView thelist=(ListView)findViewById(R.id.MyListView);
   String[] timegone=timepass.split(":");
    ListAdapter theAdapter=new ArrayAdapter<String>(this,**android.R.layout.simple_list_item_1**,timegone);

    thelist.setAdapter(theAdapter);


    }

}

And thats how it doesnt work :

public class Shifts extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

  setContentView(R.layout.shifts);
    Intent MyIntent=getIntent();
    String timepass=MyIntent.getExtras().getString("time");

    ListView thelist=(ListView)findViewById(R.id.MyListView);
   String[] timegone=timepass.split(":");
    ListAdapter theAdapter=new ArrayAdapter<String>(this,**R.layout.row_layout**,timegone);

    thelist.setAdapter(theAdapter);


    }
}

This is the row_layout.xml that im using in the adapter

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainScreen"
android:id="@+id/ly"

>
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/tv1"
    android:textSize="30sp"
    android:textStyle="bold"
    android:padding="15dp"/>

     </LinearLayout>

What should I do in order to fix this ? Thank you!

You need to create custom adapter if you want custom layout of list row..

here you can see the example.
