So you have a FooDialogPreference<\/strong> class which extends DialogPreference<\/strong>, and one of the things you’d like to do to it, is to change the Dialog’s title.<\/p>\n

DialogPreference<\/strong> happens to be a bit of a bitch, you can’t just call getDialog()<\/strong> and start playing with its features before it is shown because the Dialog<\/strong> object is only created when\u00a0DialogPreference.showDialog()<\/strong>is called.<\/p>\n

However, there’s ONE entry point where you can make your magic happen.<\/p>\n

If we look at the code of
\nDialogPreference.showDialog()<\/strong>
\nfrom the geniuses at the Android project, some gentle soul added a call to
\nonPrepareDialogBuilder(mBuilder);<\/strong> which is a method you’re meant to override.<\/p>\n

Override this method, and then with the builder<\/strong> object you’ve received you will be able to call:<\/p>\n

builder.setCustomTitle(myCustomTitleView);<\/strong><\/p>\n

However, there’s a couple of things you need to do:<\/p>\n

    \n
  1. Instantiate your myCustomTitleView<\/strong> object on the implementation of your onBindDialogView<\/strong>, and keep the reference as a private property of your\u00a0FooDialogPreference\u00a0<\/strong>class.<\/p>\n<\/li>\n
  2. \n

    Make sure to detach it from it’s parent ViewGroup<\/strong>, otherwise you will get an IllegalStateException<\/strong> from android.view.ViewGroup.addViewInner()<\/strong> letting you know this view you’re trying to add, cannot have a parent.<\/p>\n<\/li>\n<\/ol>\n

    This is what I had to do:<\/p>\n

    [pastacode lang=”java” manual=”final%20ViewGroup%20parent%20%3D%20(ViewGroup)%20myCustomTitleView.getParent()%3B%0Aparent.removeView(myCustomTitleView)%3B%0Abuilder.setCustomTitle(myCustomTitleView)%3B” message=”” highlight=”” provider=”manual”\/]<\/p>\n

    That’s all folks!<\/p>\n","protected":false},"excerpt":{"rendered":"
