Android Gradle: can't find symbol variable

由 狂风中的少年 提交于 2019-12-07 06:34:57
问题 I have a error when building with gradle that says, error: cannot find symbol variable [image_name] . I'm using ContextCompat.getDrawable(getActivity(), R.drawable.[image_name]) I have been googling all over until I found this method to get a drawable without using a deprecated method or setting my min sdk to 21. But now, gradle says it can't find a symbol variable. I have my image in the drawable folder. If you need anything, comment please. EDIT: res: drawable (images under here) drawable

Unexpected LayerDrawable behavior when drawing layers containing InsetDrawable's

由 最后都变了- 提交于 2019-12-07 05:57:02
问题 I am trying to build a LayerDrawable in xml where upper layers will occasionally completely obscure lower layers. To make the lower layers smaller, I am using an InsetDrawable to wrap another drawable to make it smaller than the full size of the view. I find unexpectedly, however, that any layers placed on top of the layer containing the inset also has the inset applied to it. I can't find documentation supporting this behavior, and am confused why this would be the case. In the example below

问题 I am trying to use an image as background in my android app. If the image doesn't fit the screen I want the image to be centered horizontally and topped vertically.

Drawable selector not working in Jelly Bean

由 久未见 提交于 2019-12-06 18:26:12
问题 I have a drawable selector as a background for each item in a ListView to highlight the selected row. Eveything works fine in Ice Cream Sandwich, but doesn't seem to work in Jelly Bean. Can't find any documentation saying what changes could have caused it to stop working and what I need to do to fix it. By not working, I mean when I click on a row in the ListView the item's background color isn't turning the @color/blue color, but it does in ICS. This is the selector code I'm using (listing

setColorFilter is not working sometimes on android drawable

由 99封情书 提交于 2019-12-06 14:24:30
I am trying to apply color filter on drawable depending on selected primary color in preferences by user. This is the piece of code I am using. getResources().getDrawable(R.drawable.ic_batman_1) .setColorFilter(ColorHelper.getPrimaryColor(), PorterDuff.Mode.OVERLAY); Problem is that, sometimes, this piece of code does not change the color filter of drawable. I have placed this code in my activity (main activity) onCreate and onResume method. So as soon as app launches, I want this color filter to be applied on that drawable but sometimes it is not happening. I also noticed that this problem is
