    <p>As long as an <code>EditText</code> with <code>ListView</code> is difficult to figure out, I tried another solution : A <code>ListView</code> with <code>TextViews</code> and when you click on one, I catch the focused <code>TextView</code> with a listener (a <code>OnItemClickListener</code> on the parent <code>ListView</code>) and I open an <code>AlertDialog</code>.</p> <p><strong>ISSUE</strong> : When I press the OK button on the <code>AlertDialog</code>, I want the focused <code>TextView</code> to get the text value of the alert dialog's <code>EditText</code>, but it doesn't work, he keeps the same text value. On activity : </p> <pre><code> listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; a, View v, int pos, long id){ InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0); id ++; t = new TextView(activity); t = (TextView) v; AlertDialog.Builder alert = new AlertDialog.Builder(activity); alert.setTitle("Title"); alert.setMessage("Message"); // Set an EditText view to get user input final EditText input = new EditText(activity); input.setText(t.getText()); alert.setView(input); alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { //Changer la valeur dans la base et dans la liste InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.toggleSoftInput(InputMethodManager.HIDE_NOT_ALWAYS,0); t.setText(input.getText()); System.out.println("input avant : " + t.getText()); } }); alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { // Canceled. } }); alert.show(); } }); </code></pre> <p>I think this code is enough for you to know what's wrong in my code. Just to let you know :</p> <ul> <li><code>ListView</code> and <em>t</em> (<code>TextView</code>) are declared as private variables on the activity class</li> <li>there is an <code>Adapter</code> class that builds automatically the <code>TextView</code> list</li> <li>if I change the value of an <code>EditText</code> on the <code>ListView</code> listener, it works, but in the dialog alert listener, it doesn't.</li> </ul> <p>Ask if you want more info.</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.
