    <p>I have parsed an xml and used them in a listview. But there is a problem. I will write two class here. One of them is <strong>HaberAdapter.java</strong> that my custom adapter class.</p> <pre><code>package haberler; import java.util.Currency; import com.applogist.kusadasibelediyesi.R; import com.nostra13.universalimageloader.core.ImageLoader; import com.nostra13.universalimageloader.core.ImageLoaderConfiguration; import android.content.Context; import android.text.Html; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.webkit.WebView.FindListener; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; import android.widget.Toast; public class HaberAdapter extends BaseAdapter implements OnItemClickListener { HaberRSS haberrss = null; private ImageLoader imageloader; Context context; private LayoutInflater inflater = null; public HaberAdapter(Context context,HaberRSS haberrss) { this.context = context; this.haberrss = haberrss; inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); imageloader = ImageLoader.getInstance(); imageloader.init(ImageLoaderConfiguration.createDefault(context)); } @Override public int getCount() { return haberrss.getItems().size(); } @Override public HaberlerItems getItem(int position) { return haberrss.getItems().get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View vi = convertView; if(convertView == null) vi = inflater.inflate(R.layout.haber_rss_item, null); HaberlerItems currentItem = (HaberlerItems)getItem(position); TextView lblTitle = (TextView) vi.findViewById(R.id.lblTitle); TextView lblDescription = (TextView) vi.findViewById(R.id.lblDescription); ImageView imgHaber = (ImageView) vi.findViewById(R.id.imgHaber); lblTitle.setText(currentItem.getTitle()); lblDescription.setText(currentItem.getDescription()); imageloader.displayImage(currentItem.getImageUrl(), imgHaber); return vi; } @Override public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { Toast.makeText(context, String.valueOf(position), Toast.LENGTH_SHORT).show(); } </code></pre> <p>}</p> <p>Items are that I get from </p> <pre><code> public class HaberlerItems { private String title; private String description; private String shortDesc; private String dateAdded; private List&lt;HaberlerImage&gt; imageList; private String imageUrl; public String getImageUrl() { return imageUrl; } public void setImageUrl(String imageUrl) { this.imageUrl = imageUrl; } public List&lt;HaberlerImage&gt; getImageList() { return imageList; } public void setImageList(List&lt;HaberlerImage&gt; imageList) { this.imageList = imageList; } public HaberlerItems() { setTitle(null); setDescription(null); setShortDesc(null); setDateAdded(null); } public void setTitle(String title) { this.title = title; } public String getTitle() { return title; } public void setDescription(String description) { this.description= description; } public String getDescription() { return description; } public String getShortDesc() { return shortDesc; } public void setShortDesc(String shortDesc) { this.shortDesc = shortDesc; } public String getDateAdded() { return dateAdded; } public void setDateAdded(String dateAdded) { this.dateAdded = dateAdded; } </code></pre> <p>}</p> <p>when i execute the app nothing is displaying on listview. In the other words displaying is an empty listview. I cant find the problem. </p> <p>An also <strong>haber_rss_item.xml</strong> is ;</p> <pre><code> &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" &gt; &lt;LinearLayout android:id="@+id/lnMain" android:layout_width="match_parent" android:layout_height="100dip" android:layout_marginBottom="5dip" android:layout_marginLeft="5dip" android:layout_marginRight="5dip" android:layout_marginTop="5dip" android:orientation="vertical" &gt; &lt;LinearLayout android:id="@+id/lnUst" android:layout_width="match_parent" android:layout_height="20dip" android:layout_marginLeft="5dip" android:layout_marginRight="5dip" android:gravity="left|center" &gt; &lt;TextView android:id="@+id/lblTitle" android:layout_width="match_parent" android:layout_height="wrap_content" android:lines="1" android:maxLines="1" android:text="" android:textColor="@color/blue" android:textSize="14sp" &gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/lnAlt" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginBottom="5dip" android:layout_marginLeft="5dip" android:layout_marginRight="5dip" android:gravity="center" android:weightSum="10" &gt; &lt;LinearLayout android:id="@+id/lnImage" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="3" &gt; &lt;ImageView android:id="@+id/imgHaber" android:layout_width="match_parent" android:layout_height="match_parent" android:scaleType="fitXY" &gt; &lt;/ImageView&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/lnDescription" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="6" &gt; &lt;TextView android:id="@+id/lblDescription" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="2dip" android:layout_marginRight="2dip" android:maxLines="5" android:text="" android:textColor="@color/black" android:textSize="12sp" &gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/lnOk" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" &gt; &lt;ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" &gt; &lt;/ImageView&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
