POTitanium: Trap android back button
text
Body
copied!<p>I'd like to capture the android back button to force confirmation before exiting the app. My app is a two window/two tab app, based on the skeleton that the titanium cli creates. I've tried all three approaches below. As far as I can tell, the back button is never trapped, the app just closes when the back button is pressed.</p> <p>Titanium 3.2.0 CLI OS X 10.9</p> <pre><code> // below true of all windows: // modal: true, // exitOnClose:true // android:back and androidback have been tried Ti.App.addEventListener('androidback', function(e){ var confirmClear = Titanium.UI.createAlertDialog({ message:'Exit App?', buttonNames: ['Yes','No'] }); confirmClear.show(); confirmClear.addEventListener('click',function(e) { if (e.index === 0) { win1.close(); } }); }); ////////////////////////////////////////////////// win1.addEventListener('androidback', function(e){ var confirmClear = Titanium.UI.createAlertDialog({ message:'Exit App?', buttonNames: ['Yes','No'] }); confirmClear.show(); confirmClear.addEventListener('click',function(e) { if (e.index === 0) { win1.close(); } }); }); ////////////////////////////////////////////////// win2.addEventListener('androidback', function(e){ var confirmClear = Titanium.UI.createAlertDialog({ message:'Exit App?', buttonNames: ['Yes','No'] }); confirmClear.show(); confirmClear.addEventListener('click',function(e) { if (e.index === 0) { win2.close(); } }); }); </code></pre> <p>After reading the suggestions, here's my now working code:</p> <pre><code>tabGroup.addEventListener('androidback', function(e){ var confirmClear = Titanium.UI.createAlertDialog({ message:'Exit App?', buttonNames: ['Yes','No'] }); confirmClear.show(); confirmClear.addEventListener('click',function(e) { if (e.index === 0) { tabGroup.close(); } }); }); </code></pre>
