    <p>I believe the code below will do what you want but I can't see a way to do this only in the xml layout. Basically I have added a textChangedListener to two different TextViews that have the two different layout options I believe you are looking for, both inside their own relative layout with the date displaying textview. When the subtitle is set the first of these is used to hold the text, if it requires more than a single line the second TextView is used and in either case the other has its visibility option set to GONE. In my example I use a seperate thread to change the subtitle, hopefully this doesn't confuse things too much.</p> <p>The layout xml is as follows:</p> <pre><code> &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" &gt; &lt;TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:ellipsize="end" android:textAppearance="?android:attr/textAppearanceSearchResultTitle" android:background="#FF009999" android:textIsSelectable="false" android:text="@string/my_title" /&gt; &lt;RelativeLayout android:id="@+id/resizingTextContainer" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/title" &gt; &lt;TextView android:id="@+id/date" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:textAppearance="?android:attr/textAppearanceSearchResultSubtitle" android:textIsSelectable="false" android:textColor="#FFFFFFFF" android:background="#FF000000" /&gt; &lt;TextView android:id="@+id/subtitle1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toLeftOf="@+id/date" android:textAppearance="?android:attr/textAppearanceSearchResultSubtitle" android:textIsSelectable="false" android:textColor="#FFFFFF" android:background="#FF00FF00" /&gt; &lt;TextView android:id="@+id/subtitle2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/date" android:textAppearance="?android:attr/textAppearanceSearchResultSubtitle" android:textIsSelectable="false" android:visibility="gone" android:textColor="#FFFFFF" android:background="#FF00FF00" /&gt; &lt;/RelativeLayout&gt; &lt;Button android:id="@+id/startTestBtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/resizingTextContainer" android:layout_centerHorizontal="true" android:text="Click To Begin" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>And the main activity code with the textview switching logic:</p> <pre><code> package com.example.code.examples.changelayoutwithtextlength; import android.os.Bundle; import android.app.Activity; import android.text.Editable; import android.text.TextWatcher; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button;

DateTextView.setText("29th April 2013"); Button b = (Button)findViewById(R.id.startTestBtn); b.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { v.setEnabled(false); Thread thread = new testSubtitleThread(); thread.start(); } }); TextView tv = (TextView)findViewById(R.id.subtitle1); tv.addTextChangedListener(textChangeDisplayCheck); TextView tv2 = (TextView)findViewById(R.id.subtitle2); tv2.addTextChangedListener(textChangeDisplayCheck);

tv2.setText(newSubtitle); tv2.setVisibility(View.VISIBLE); } else { tv.setVisibility(View.VISIBLE); } tv.addTextChangedListener(textChangeDisplayCheck); tv2.addTextChangedListener(textChangeDisplayCheck); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } public class testSubtitleThread extends Thread { String[] subtitles = new String[] { "a short one", "a really long winded subtitle that will take over more than the allowed space", "tiny", "Really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, long.", ".....", "text just to long to fit on my device"}; private android.os.Handler handler = new android.os.Handler() { @Override public void handleMessage(android.os.Message msg) { if(msg.what &lt; subtitles.length) { TextView tv = (TextView)findViewById(R.id.subtitle1); tv.setText(subtitles[msg.what]); } else { Button b = (Button)findViewById(R.id.startTestBtn); b.setEnabled(true); } } }; @Override public void run() { for(int i = 0; i &lt;= subtitles.length; i++) { handler.sendEmptyMessage(i); try { Thread.sleep(3000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } } </code></pre> <p>I hope this helps.</p>

    1. COSeems to be there as a solution, so I'll accept. Sadly it seems to be a bit of a faff just to get the effect I was going for, so I've instead set `android:maxLines="1"` on the date TextView and set the subtitle to be `android:layout_toLeftOf="@+id/date"` and removed the date's `android:layout_toRightOf="@+id/subtitle"`. This means that the date is always on a single line on the right and padding keeps the subtitle suitable contained in its spot on the left (possibly consuming multiple lines). Thank you anyway for your solution to my question :)

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).
