I'm basicly follow this site: <a href="http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/" rel="nofollow">http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/</a> but somehow my adapter doesn't work right... And do not fill my listView... </p> <p>I create a new object from my main class like: fillLeftMenu lmenu = new fillLeftMenu(menu);</p> <p>I used this line for having started the activity, if it's not wrong:</p> <pre><code>startActivity(new Intent("com.yahya.training.FILLLEFTMENU")); </code></pre> <p>On my AndroidManifest.xml, i added this following lines:</p> <pre><code> &lt;activity android:name=".fillLeftMenu" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="com.yahya.training.FILLLEFTMENU" /&gt; &lt;category android:name="android.intent.category.DEFAULT" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; </code></pre> <p>And the fillLeftMenu class is:</p> <pre><code>public class fillLeftMenu extends ListActivity { private ProgressDialog myProgressDialog = null; private View menu; ImageView findLocation; Spinner cityList; ListView leftList; String [] textIndex; Drawable [] imageIndex; ArrayList&lt;LeftListItems&gt; Left; listAdapter lAdapter; public fillLeftMenu(View Lmenu) { this.menu = Lmenu; } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); findLocation = (ImageView) menu.findViewById(R.id.image_findLocation); leftList = (ListView) menu.findViewById(R.id.list); // add items to listView Left = new ArrayList&lt;LeftListItems&gt;(); textIndex = new String[] {"Bugünün Fırsatları", "Son Dakika Bonusları", "Kadın", "Aile", "Çocuk", "Alışveriş", "Şehirden Kaçış", "Kışa Özel"}; imageIndex = new Drawable[] {leftList.getResources().getDrawable(R.drawable.kucukicon_01),leftList.getResources().getDrawable(R.drawable.kucukicon_02),leftList.getResources().getDrawable(R.drawable.kucukicon_03),leftList.getResources().getDrawable(R.drawable.kucukicon_04),leftList.getResources().getDrawable(R.drawable.kucukicon_05),leftList.getResources().getDrawable(R.drawable.kucukicon_06),leftList.getResources().getDrawable(R.drawable.kucukicon_07),leftList.getResources().getDrawable(R.drawable.kucukicon_08)}; lAdapter = new listAdapter(menu.getContext(), R.layout.list_item, Left); leftList.setAdapter(lAdapter); Runnable viewOrders = new Runnable(){ public void run() { getIndex(); } }; Thread thread = new Thread(null, viewOrders, "MagentoBackground"); thread.start(); myProgressDialog = ProgressDialog.show(fillLeftMenu.this,"Please wait...", "Retrieving data ...", true); leftList.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { } }); } private Runnable returnRes = new Runnable() { public void run() { if(Left != null &amp;&amp; Left.size() &gt; 0){ lAdapter.notifyDataSetChanged(); for(int i=0;i&lt;Left.size();i++) lAdapter.add(Left.get(i)); } myProgressDialog.dismiss(); lAdapter.notifyDataSetChanged(); } }; private void getIndex() { try{ LeftListItems item = new LeftListItems(); for(int i=0; i&lt;textIndex.length; i++) { item.setText(textIndex[i]); item.setImage(imageIndex[i]); Left.add(item); } } catch (Exception e) { Log.e("BACKGROUND_PROC", e.getMessage()); } runOnUiThread(returnRes); } private class listAdapter extends ArrayAdapter&lt;LeftListItems&gt; { private ArrayList&lt;LeftListItems&gt; items; private Context ctx; public listAdapter(Context ctx, int textViewResourceId, ArrayList&lt;LeftListItems&gt; items) { super(ctx, textViewResourceId, items); this.ctx = ctx; this.items = items; } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { // LayoutInflater inflater = LayoutInflater.from(ctx); // v = inflater.inflate(R.layout.list_item, null); LayoutInflater vi = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.list_item, null); } LeftListItems index = items.get(position); if(index != null) { TextView text = (TextView) v.findViewById(R.id.text); ImageView img = (ImageView) v.findViewById(R.id.icon); if(text != null) text.setText(index.getText()); if(img != null) img.setBackgroundDrawable(index.getImage()); } return v; } } } </code></pre>
