When should one use android:clickable?

When should we use android:clickable in XML? Should we ever?
Is there any difference between such XML declaration and in-code declaration myButton.setOnClickListener? I have read the documentation, but I could not find out when and why should I ever use this attribute.

PS. I was implementing an ad SDK and found that their developers were using android:clickable with WebView and I was intrigued why did they use it.

Solution

  • As the documentation states, and as far as I know :

    clickable - Defines whether this view reacts to click events. Must be a boolean value, either "true" or "false".

    So for example if you just declare a Webview or View in your layout.xml and try to set an OnClickListener on this views the OnClick event won't be fired unless you specify the attribute : 

      android:clickable=true
