Android: How to Make A Drawable Selector

由 ▼魔方 西西 提交于 2019-11-27 09:01:22
I feel like this is kind of a silly question, but here I go anyways. I have an image button, and I want to be able to change it's image everytime it is clicked. The API seems to say that the best way to go about doing this is to create xml resource in the drawable folder that contains a selector and values. However when I go to make a new android xml resource, there's no option for drawables. What am I missing? As far as I know, the Android XML editor doesn't allow you to create XML drawables. You have to go to the source tab (labeled: filename.xml) and paste in the text manually. It should

I have this problem, see the trace stack: E/AndroidRuntime(2410): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #5: <bitmap> requires a valid src attribute My xml file looks like: <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <bitmap android:src="@drawable/btn_1"/> </item> </layer-list> btn_1 is another xml file in drawable resources When i'm using an image(*.png) instead of xml drawable it's ok. Can I use a drawable resource as src to bitmap? Just in case here is my btn_1.xml file. It doesn't work even if btn_1 file have no items.

问题 What is the best way to set background for some view? For example 2 variants of backround: background with gradient, rounded corners and border background with just one color and rounded corners So which of variants would be better, nine-patch or drawable xml resource? 回答1: My guess is, NinePatch would be slightly faster in most cases. Here's what I found. GradientDrawable (the one used for rects in xml) uses this code to call through to Canvas which in turn uses native call leading to

由 删除回忆录丶 提交于 2019-11-26 23:23:41
I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center. Does anyone know how to get it right? the stroke needs to be the bottom line/border. I am using the shape as a background to a TextView. Please, never mind why I need it. <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <shape android:shape="rectangle" > <solid android:color="#1bd4f6" /> </shape> </item> <item> <shape android:shape="line" > <padding android

Understanding Android&#39;s <layer-list>

问题 I don\'t understand how the layer-lists work. I read the official documentation with some examples but it does not work for me like expected. I want four squares which should be padded with 1dp, but nothing is like expected. Here is a screenshot scaled by 500%: (The wrong colors do not matter) As you can see the size is completely wrong and the paddings are missing. I tried to set real values like width/height and right/left/top/buttom to be sure that android get the point what I want. Here
