OnItemClicked not getting called in ListView

Question

I've read as many examples as i could find and it seems like i am implementing this correctly but the click never registers. My OnItemClicked Listener is not getting called though it seems to be implemented correctly.

public class Playlist extends ListActivity implements OnItemClickListener{
    private int list_layout = R.layout.playlist;
    private Context context;
    private PlaylistAdapter adapter;
    private Cursor cursor = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(list_layout);
        context = this.getApplicationContext();
        adapter = new PlaylistAdapter(context, cursor, FLAGS);
        ListView list_view = getListView();
        list_view.setOnItemClickListener(this);

        ...
    }

    @Override
    public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {
        Toast.makeText(Playlist.this, "click", Toast.LENGTH_LONG).show();
        startSong(position);
    }
}

ListView:

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

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ff525252"
        android:layout_weight="1"

        />

</LinearLayout>

ListView Row:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="50sp"
    android:background="#ffafafaf"
    >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="15sp"
        android:id="@+id/songname"
        android:autoText="false"
        android:textColor="#ff000000"
        android:layout_alignParentTop="true"
        android:maxLines="1"
        android:padding="1sp"
        android:textIsSelectable="false"
        android:clickable="false"/>

   <Button>
        android:layout_width="50sp"
        android:layout_height="50sp"
        android:text="="
        android:id="@+id/options"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />


    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/artistname"
        android:textColor="#ff585858"
        android:textSize="12sp"
        android:layout_below="@+id/songname"
        android:padding="1sp"
        android:minLines="1"
        android:textIsSelectable="false"
        android:clickable="false"/>

</RelativeLayout>

EDIT: Sorry. I did not mean for this to be such a bad question. I will do my best to salvage it.

lv.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1,
                        int arg2, long arg3) {

                    try {

                         //  YOUR STUFF


                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }
            });

Problem in Xml File on Listview

<ListView
     android:id="@+id/list"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_weight="1"
     android:background="#ff525252"
     android:clickable="true" >
</ListView>

Answer 3

Add entire XML code to your question(if you used RelativeLayout or FrameLayout)

and check android:id="@+id/list"

 listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            startSong(arg2);

        }
    });

or try with your getView parameter View/inflate list item onclick listener

     view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {   
                 //do stuff
            }
        });

Answer 4

There are many duplicate questions of this type, but the one that turned out to be relevant to my problem was solved HERE.

"If any row item of list contains focusable or clickable view then OnItemClickListener won't work."

The row item must have a param like android:descendantFocusability="blocksDescendants".

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="50sp"
    android:background="#ffafafaf"
    android:descendantFocusability="blocksDescendants"
