Android ListView onItemClickListener заблокирован ProgressBar

У меня был мой onItemClickListener, который работал над моим списком ListView внутри моего DrawerLayout. Но я добавил ProgressBar, который отображается раньше всего, тогда он установлен в View.GONE. Тем не менее, я больше не могу выбирать и элементы из своего списка.

list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:descendantFocusability="blocksDescendants" >

<TextView
    android:id="@+id/label"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#000000"
    android:focusable="false"
    android:paddingBottom="25dp"
    android:textColor="#ffffff"
    android:textSize="20sp" >
</TextView>

</RelativeLayout>

main_activity.xml:

<android.support.v4.widget.DrawerLayout       xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<FrameLayout
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</FrameLayout>

<ListView
    android:id="@+id/drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="left"
    android:background="#000"
    android:choiceMode="singleChoice" />

<ProgressBar
    android:id="@+id/device_progress"
    style="?android:attr/progressBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:indeterminateDrawable="@drawable/progress"
    android:visibility="gone" />

</android.support.v4.widget.DrawerLayout>

Код Java:

    super.onCreate(savedInstanceState);
    Log.d(TAG, "Executing onCreate().");
    setContentView(R.layout.activity_devices);

    progress.setVisibility(View.VISIBLE);
    manager = MainScreenActivity.getDeviceManager();
    manager = MainScreenActivity.getDeviceManager();
    drawerInfo = manager.getDrawerInfo();
    mDrawerList = (ListView) findViewById(R.id.drawer);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    adapter = new ArrayAdapter<String>(this,
            R.layout.drawer_list_item, R.id.label, drawerInfo);
    mDrawerList.setAdapter(adapter);
    mDrawerLayout
            .setDrawerListener(new DrawerLayout.SimpleDrawerListener() {
                @Override
                public void onDrawerClosed(View drawerView) {
                    super.onDrawerClosed(drawerView);
                    Log.d(TAG, "onDrawerClosed() executed!");
                }

                @Override

                    Log.d(TAG, "onDrawerOpened() executed!");
                    refreshDrawer();
                }
            });
    mDrawerList.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                final int pos, long id) {
            Log.d(TAG, "CLICKED " + pos);
            selectDevice(pos);
        }
    });
}
