    <p>I have ListView that has some kind of events on it. Events are sorted by day, and I would like to have header with date on it for every day, and then events listen below.</p> <p>Here is how I populate that list:</p> <pre><code>ArrayList&lt;TwoText&gt; crs = new ArrayList&lt;TwoText&gt;(); crs.add(new TwoText("This will be header", event.getDate())); for (Event event : events) { crs.add(new TwoText(event.getStartString() + "-" + event.getEndString(), event.getSubject())); } arrayAdapter = new TwoTextArrayAdapter(this, R.layout.my_list_item, crs); lv1.setAdapter(arrayAdapter); </code></pre> <p>and this is how my class TwoText looks:</p> <pre><code>public class TwoText { public String classID; public String state; public TwoText(String classID, String state) { this.classID = classID; this.state = state; } } </code></pre> <p>and this is how my TwoTextArrayAdapter class looks:</p> <pre><code>import java.util.ArrayList; import android.app.Activity; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.TextView; public class TwoTextArrayAdapter extends ArrayAdapter&lt;TwoText&gt; { private ArrayList&lt;TwoText&gt; classes; private Activity con; TextView seperator; public TwoTextArrayAdapter(Activity context, int textViewResourceId, ArrayList&lt;TwoText&gt; classes) { super(context, textViewResourceId, classes); this.con = context; this.classes = classes; } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.my_list_item, null); } TwoText user = classes.get(position); if (user != null) { TextView content1 = (TextView) v.findViewById(R.id.list_content1); TextView content2 = (TextView) v.findViewById(R.id.list_content2); if (content1 != null) { content1.setText(user.classID); } if(content2 != null) { content2.setText(user.state); } } return v; } } </code></pre> <p>and this is my_list_item.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" &gt; &lt;TextView style="?android:attr/listSeparatorTextViewStyle" android:id="@+id/separator" android:text="Header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="#757678" android:textColor="#f5c227" /&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" &gt; &lt;TextView android:id="@+id/list_content1" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_margin="5dip" android:clickable="false" android:gravity="center" android:longClickable="false" android:paddingBottom="1dip" android:paddingTop="1dip" android:text="sample" android:textColor="#ff7f1d" android:textSize="17dip" android:textStyle="bold" /&gt; &lt;TextView android:id="@+id/list_content2" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_margin="5dip" android:clickable="false" android:gravity="center" android:linksClickable="false" android:longClickable="false" android:paddingBottom="1dip" android:paddingTop="1dip" android:text="sample" android:textColor="#6d6d6d" android:textSize="17dip" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre> <p>what I do at the moment is that I am adding header just as regular list object, but Id like it to be as header and in my case have a date on it.</p> <p>I have this code in my xml for header:</p> <pre><code>&lt;TextView style="?android:attr/listSeparatorTextViewStyle" android:id="@+id/separator" android:text="Header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="#757678" android:textColor="#f5c227" /&gt; </code></pre> <p>and I tried hiding it when it is unneccessary and showing it when neccessary but I just messed up rest of my code. I tried few more tutorials but they also had same effect.</p> <p>Could anyone guide me on how to do that easy way?</p>

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.

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