    <p>In the application I'm doing, I'm trying to make it do something different depending on the text so I have a code which supposedly retrieves the texto of the row I clicked and then with an if else it tells the program to do something different depending on the code.</p> <pre><code>@Override protected void onListItemClick(ListView l, View v, int position, long id) { int selectionRowID = (int) this.getSelectedItemId(); String selectedFileString = this.directoryEntries.get(selectionRowID); if (selectedFileString.equals(".")) { this.browseToSD(); } else if(selectedFileString.equals("..")) { this.upOneLevel(); } else { File clickedFile = null; clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID)); if(clickedFile != null) this.browseTo(clickedFile); } } </code></pre> <p>But it doesn't work, this: "selectedFileString.equals(".")" is always TRUE so it always does browseToSD, but sometimes the text is ".." and most of the times it's something completely different so the app doesn't do what it's suppose to do. I tried to change the code to this:</p> <pre><code>@Override protected void onListItemClick(ListView l, View v, int position, long id) { ListView lv = getListView(); ListAdapter list_adapter = lv.getAdapter(); TextView var_x = (TextView) list_adapter.getView(0,null,null); if (var_x.equals(".")) { this.browseToSD(); } else if(var_x.equals("..")) { this.upOneLevel(); } else { File clickedFile = null; clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID)); if(clickedFile != null) this.browseTo(clickedFile); } } </code></pre> <p>But this doesn't work either, "var_x.equals(".")" and "var_x.equals("..")" are always false. I'm really new to programming with Java and Android so I don't have a clue why it doesn't work, any ideas?</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.
