Custom navigation drawer nereaguje na uživatelské podměty – Java – Fórum – Programujte.com

dělám custom drawer., který obsahuje tlačítko a ExpandaleListView, drawer se normálně vysune, když je potřeba, ale tlačítko ani ListView nereagují na podměty. ListView nescroluje.

 drawer.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

ActivityMain

drawerLayout = (DrawerLayout) findViewById(R.id.a_drawer_layout);

		OfferListView = (ExpandableListView) findViewById(R.id.a_main_lv_offer);
		offerAdapter = new LeftPanelOfferAdapter(this, database);
		OfferListView.setAdapter(offerAdapter);

		ImageButton addItem = (ImageButton) findViewById(R.id.a_main_drawer_btn_add);
		addItem.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				Toast.makeText(ActivityMain.this, "Nefunguje", Toast.LENGTH_LONG).show();
				
			}
		});
		
		
		drawerLayout.openDrawer(GravityCompat.START);

Teď jsem zkusil přidat pár listenerů a zdá se, že drawer vůbec neregistruje ani onTouch.
