    <p>I am adding items to a ListView dynamically and i have the Problem that new Entries only get displayed when i touch the screen of the phone.</p> <p>I am using this code to add a new item:</p> <pre><code>public TimerTask tt = new TimerTask() { @Override public void run() { LoadChatData bdl = new LoadChatData(new OnTaskComplete() { @Override public void onTaskCompleted(ArrayList&lt;ChatListItem&gt; item, int id) { currid = id; for (ChatListItem i : item) { dataarr.add(i); } chatList.notifyDataSetChanged(); } }); bdl.execute(XXX); } }; </code></pre> <p>chatList is the adapter and dataarr the Data which the adapter holds. The entries gets added but only when i touch the phone screen they get shown.</p> <p>My custom Adapter looks like this:</p> <pre><code>import java.util.ArrayList; import android.content.Context; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.RelativeLayout; import android.widget.TextView; public class ChatList extends BaseAdapter { java.util.List&lt;ChatListItem&gt; data = null; Context context; int layoutResourceId; public String me = null; public void setId(String aid){ this.me = aid; } public ChatList(Context context, int layoutResourceId, ArrayList&lt;ChatListItem&gt; data) { this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; ChatHolder holder = null; ChatListItem entry = data.get(position); if (row == null) { LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); row = inflater.inflate(layoutResourceId, parent, false); holder = new ChatHolder(); holder.txtText = (TextView) row.findViewById(R.id.txtText); holder.txtUser = (TextView) row.findViewById(R.id.txtUser); holder.txtVersion = (TextView) row.findViewById(R.id.txtVersion); holder.txtZeit = (TextView) row.findViewById(R.id.txtZeit); holder.background = (RelativeLayout) row.findViewById(R.id.backgroundlayout); row.setTag(holder); } else { holder = (ChatHolder) row.getTag(); } int status = Integer.parseInt(entry.status); /* * android:paddingBottom="5dp" android:paddingLeft="5dp" * android:paddingRight="15dp" android:paddingTop="5dp" */ if (entry.uid.equals(me)) { holder.background.setPadding(20, 5, 30, 5); holder.background.setBackgroundResource(R.drawable.chatitem_me); } else { holder.background.setPadding(30, 5, 20, 5); holder.background.setBackgroundResource(R.drawable.chatitem); } holder.txtUser.setTextColor(0xFF000000); holder.txtText.setTextColor(0xFF000000); Log.d("Info", "status is : " + status); if (status == 1) { holder.txtUser.setTextColor(0xFF005CE6); } else if (status == 2) { holder.txtUser.setTextColor(0xFFD67600); } else if (status == 3) { holder.txtUser.setTextColor(0xFF000000); } else if (status == 4) { holder.txtUser.setTextColor(0xFFDB0000); holder.txtText.setTextColor(0xFF660000); } else if (status == 5) { holder.txtUser.setTextColor(0xFF009933); holder.txtText.setTextColor(0xFF003300); } holder.txtText.setText(entry.text); holder.txtUser.setText(entry.user); holder.txtVersion.setText(entry.v); holder.txtZeit.setText(entry.time); return row; } static class ChatHolder { RelativeLayout background; TextView txtText; TextView txtUser; TextView txtVersion; TextView txtZeit; } @Override public int getCount() { return data.size(); } @Override public ChatListItem getItem(int arg0) { return data.get(arg0); } @Override public long getItemId(int arg0) { // TODO Auto-generated method stub return 0; } } </code></pre>

Guidance
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.

SQuiL has stopped working due to an internal error.

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