Custom ProgressBar

由 这一生的挚爱 提交于 2019-11-26 12:29:18
问题 I am trying to create a ProgresBar that looks like the following: So far, I have created an object which extends ProgressBar, and now I am trying to figure out what my next step is. I know that I need to override onDraw() with some logic that will decide how many squares to color in. This is trivial. What I don\'t know how to do is get these squares in the first place. How can I replace the default drawable, so when I add my custom bar in the layout I can see something like my image? 回答1: try

How to reference style attributes from a drawable?

由 随声附和 提交于 2019-11-26 11:07:32
I want to have 2 selectable themes for my application. In order to do that, I defined some attributes, like this: <attr format="color" name="item_background" /> Then, I created both themes, like this: <style name="ThemeA"> <item name="item_background">#123456</item> </style> <style name="ThemeB"> <item name="item_background">#ABCDEF</item> </style> This method works great, allowing me to create and modify several themes easily. The problem is that it seems that it can be used only in Views, and not in Drawables . For example, referencing a value from a View inside a layout works: <TextView

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

由 拈花ヽ惹草 提交于 2019-11-26 09:24:35
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

Mipmap drawables for icons

由 試著忘記壹切 提交于 2019-11-26 09:15:03
Since Android 4.3 (Jelly Bean) we can now make use of the res/mipmap folders to store "mipmap" images. For example, Chrome for Android stores its icons in these folders instead of the more normal res/drawable folders. How are these mipmap images different from the other familiar drawable images? I see that in my manifest, we use the @mipmap/ qualifier, instead of @drawable/ , which makes sense given the resource folder name: <activity android:name=".MipmapDemp" android:icon="@mipmap/ic_launcher" /> References: The Android 4.3 APIs document has the following to say: Using a mipmap as the source
