问题 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

问题 Trying to use LayerDrawable (defined in XML as layer-list) to layer several shape drawables onto one another; to be used as a background for a layout. The Android guide (for LayerList) says: All drawable items are scaled to fit the size of the containing View, by default. Thus, placing your images in a layer list at different positions might increase the size of the View and some images scale as appropriate. To avoid scaling items in the list, use a <bitmap> element inside the <item> element

问题 I've got a ListActivity with a ListView in it. I need to draw a repeating image around the border ("on top of it (I guess after the listview is renderered)) How can I hook in my own drawing code for this? 回答1: You can use a FrameLayout to cause the ListView to overlap with a view that fills the entire screen. In this background view you could tile an image, or write your own custom View with your own drawing method. 回答2: There is no border property in ListView, as far as I know. Instead you

问题 I'm trying to draw a rounded rectangle with a border around it using a class that extends ShapeDrawable (see here) and everything is working except that the shapedrawable seems to be cutting off some of the border because the shape itself doesn't extend outside those bounds. Is there not some way to offset where the shapedrawable starts drawing so that there is some padding between the bounds of the shape itself and the canvas? I have tried both ShapeDrawable.setBounds to larger than the

问题 I have all of my images in the drawable-hdpi folder. And I finished all of my layouts for all screen sizes. But i forgot to put the images in the drawable-mdpi folder and drawable-ldpi folder. If a phone with an mdpi screen density were to download my application would it just use the images in the drawable-hdpi folder?
