Android : How to get the dirty(changed) properties
<p>How to get the dirty(changed) properties(any controls subclasses of view) amongst a number of properties  on a layout. Does android has a dirty flag to mark if the layout has any field that has a changed content??</p>

<p>Actually, i have a layout that has a few edittexts,spinners,datewidgets.Now doing a save should make request to the server only if the user has modified anything .I wanted to know that how can i check if the user has changed anything in that layout or not.Does android has any flag or something that sets itself when the user modifies any input control?</p>

<p>Hmm..Blckberry Does have isDirty(){boolean net.rim.device.api.ui.Manager.isDirty()}method. </p>
