You are setting the listeners incorrect. In order for the listeners to work you would have to click the ListView row once to actually set the listeners for the Buttons and TextView. The correct way would be to set the listeners in the getView method when you layout the views.

First delete the code you have in the onListItemClick callback and then modify the adapter. I've rewritten your adapter to a more efficient version(although more improvements could be made). As the code is big you can find the new adapter here https://gist.github.com/3463215 . See if this is what you want.

The R.layout.video layout file:

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

<LinearLayout  android:layout_width="match_parent"
    android:layout_height="wrap_content" >
<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="One" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
     android:text="Two" />

<Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="three" />

<Button
    android:id="@+id/button4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Four" />

<Button
    android:id="@+id/button5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Five" />

</LinearLayout>

<VideoView
    android:id="@+id/videoView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

</LinearLayout>

you are doing wrong in defining click listener in onItemCLik method

just set a CLick Listener for TextView and Button in getView method of base adapter ....... i,e Remove all the click listener from OnItemClikc method

public View getView(final int position, View convertView, ViewGroup parent) {
    tf=Typeface.createFromAsset(context.getAssets(),"BFantezy.ttf"); 
    LayoutInflater inflater = context.getLayoutInflater();
    View rowView = inflater.inflate(R.layout.row, null, true);
    TextView textView = (TextView) rowView.findViewById(R.id.row_label);
    textView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            // do what ever do want to ie open activity 
            //must use postion to get that item  
        }
    });
    Button bt1=(Button) rowView.findViewById(R.id.button1); 
    bt1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent();    
            intent.setClass(ListButton.this, My_videos.class); 
            //this will send the respective  string to intent class ; 
            intent.putExtra("video", classes[position].toString);

        }
    });
return rowView;  }}
