The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome.

The android:groupIndicator property takes a state enabled drawable. That is, you can set different image for different states.
ReplyDeleteWhen the group has no children, the corresponding state is 'state_empty'
See these reference links:
http://developer.android.com/reference/android/widget/ExpandableListView.html#attr_android:groupIndicator
http://developer.android.com/reference/android/R.attr.html#state_empty
For state_empty, you can set a different image which is not confusing, or, simply use transparent color to display nothing...
Add this item in your stateful drawable along with others....
<item android:state_empty="true" android:drawable="@android:color/transparent"/>
So, your statelist can be like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_empty="true" android:drawable="@android:color/transparent"/>
<item android:state_expanded="true" android:drawable="@drawable/my_icon_max" />
<item android:drawable="@drawable/my_icon_min" />
</selector>
In case you are using an ExpandableListActivity, you can set the groupindicator in onCreate as follows:
getExpandableListView().setGroupIndicator(getResources().getDrawable(R.drawable.my_group_statelist));
I have tested this to be working.
As mentioned in a different answer, since Android treats an un-expanded list group as empty, the icon is not drawn even if the group has children.

Basically you have to set the default drawable as transparent, move the drawable into your group view as an ImageView and toggle the image in your adapter.
