================================================ ### 为什么需要Folivora 对于android开发者来说，在layout文件中引用drawable来设置`View`的背景或者`ImageView`的`src`是很常见的事情，需要我们在drawable文件夹下写好xml文件就可以应用了，但是有许多drawable文件可能只被使用了一次，也有可能我们只是为了实现一个简单的圆角背景的功能。越来越多的drawable文件导致开发和维护成本的增加，有没有什么方法可以直接在layout文件中去创建drawable呢，Folivora为你提供了这样的功能。 ### Folivora能做什么 Folivora可以为你的View设置一个背景或者ImageView的src,当前支持的drawable类型有 * shape (GradientDrawable) * selector (StateListDrawable) * ripple (RippleDrawable) * layerlist (LayerListDrawable) * levellist (LevelListDrawable) * inset (InsetDrawable) * clip (ClipDrawable) * scale (ScaleDrawable) * animation (AnimationDrawable) * 自定义的Drawable **(新增)** ### 使用方法 - **STEP1** : 添加Gradle依赖，在项目的build.gradle中加入 ```groovy dependencies { implementation 'cn.cricin:folivora:0.1.0' } ``` - **STEP2** : 在layout.xml中加入自定义的属性, 告诉Folivora如何创建drawable，Folivora提供的内置drawable属性前缀如下 * shape -> shape * selectror -> selector * layer-list -> layer * level-list -> level * clip -> clip * scale -> scale * inset -> inset * ripple -> ripple * animation -> anim 例如所有的shape属性设置的前缀都是shape, 如`shapeSolidColor`, `shapeCornerRadius`等, 在设置了`drawableType` 之后，敲出指定的前缀，IDE会自动的给出所有该drawableType可用的属性 > shape 我们来试着在xml中书写Folivora为我们提供的属性来实现上图中第一个的圆角shape效果 ```xml ``` 我们在看一下其他几种drawable的用法： > layerlist ```xml ``` > levellist ```xml ``` > selector ```xml ``` 在0.0.7版本中，Folivora加入了对创建复杂state的selector支持，使用app:selectorItemXStates指定需要的state flags，使用app:selectorItemXDrawable指定对应states的drawable(X可以是0，1，2，3，4)，现在可以用新的方式实现上面的drawable。 ```xml ``` 注：两种selector写法最好不要混用，推荐使用新的selector写法，这种方式的selector顺序是严格按照item定义的顺序添加进selector的，唯一的限制是只能定义5个states和drawables，不过对于一般的selector应该够用了 > ripple ```xml ``` 使用ripple的确是酷炫多了，但是ripple效果是5.0之后引入的，那5.0之前的设备怎么办呢，Folivora为你提供了`RippleFallback`接口，用来创建一个替换`RippleDrawable`的`Drawable`实例，让我们试着用一个selector来代替ripple: ```java Folivora.setRippleFallback(new Folivora.RippleFallback()){ @Override public Drawable onFallback(ColorStateList ripple, Drawable content, Drawable mask, Context ctx){ StateListDrawable sld = new StateListDrawable(); sld.addState(new int[]{android.R.attr.state_pressed}, new ColorDrawable(ripple.getDefaultColor())); sld.addState(new int[0], content); return sld; } } ``` > clip ```xml ``` > inset ```xml ``` > scale ```xml ``` > animation ```xml ``` 注: 如果你在layout文件中用Folivora为系统控件添加drawable，如`View`和`TextView`等，许多 IDE (Android Studio, IntelliJ) 会把这些Folivora提供的属性标注为错误，但是实际上是正确的。可以在这个View或者根ViewGroup上加上`tools:ignore="MissingPrefix"`来避免报错。为了使用 `ignore`属性，可以加上`xmlns:tools=" http://schemas.android.com/tools"`。关于这个问题，可以查看： https://code.google.com/p/android/issues/detail?id=65176. - **STEP3** : 在Activity中启用Folivora, 有两种方法： 1. ```java public class MainActivity extends Activity { @Override protected void attachBaseContext(Context newBase) { super.attachBaseContext(Folivora.wrap(newBase)); } } ``` 2. ```java public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Folivora.installViewFactory(this); setContentView(R.layout.your_layout_xml_name); } } ``` ### 使用嵌套的shape Folivora现在支持在drawable中嵌套shape了，除了animation以外，所有的drawable的子drawable除了可以使用`@drawable/xxx`和颜色之外，新增了shape/shape1/shape2/shape3/shape4这5个值，参考定义shape的例子，替换相应的前缀即可, 我们来定义嵌套了shape的selector试一试 ```xml ``` 效果是这样的 ### 使用自定义Drawable 从0.0.4版本开始，Folivora除了支持自带的drawable以外，还支持使用自定的drawable类型了，让你使用自定义drawable就和使用自定义view一样轻松。这里我们以自定义一个绘制纸风车的`WindmillDrawable`为例，来让Folivora为我们提供支持： 1. 首先我们和自定义`View`一样，为`WindmillDrawable`提供自定义的属性： ```xml ``` 可以看到，自定义属性这部分和普通的`View`自定义属性是一样的。name和自定义drawable的类名相同就行了，Folivora就可以在layout文件中为这些drawable的自定义属性提供属性的自动提示了 2. 创建自定义的`WindmillDrawable`，继承自`Drawable`, 提供一个`public WindmillDrawable(Context ctx, AttributeSet attrs)`的构造方法，在这个构造方法里就可以获取自定义的属性, 代码如下： ```java public WindmillDrawable(Context ctx, AttributeSet attrs) { TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.WindmillDrawable); int count = a.getIndexCount(); for (int i = 0; i < count; i++) { int index = a.getIndex(i); switch (index) { case R.styleable.WindmillDrawable_wdSize: mSize = a.getDimensionPixelSize(index, mSize); break; case R.styleable.WindmillDrawable_wdColor0: mColors[0] = a.getColor(index, mColors[0]); break; case R.styleable.WindmillDrawable_wdColor1: mColors[1] = a.getColor(index, mColors[1]); break; ... default://no-op unexpected attr index break; } } a.recycle(); } ``` 这部分代码其实和自定义`View`的属性获取没有什么区别，主要就是给drawable添加一个构造方法，具体绘制代码就不贴了，如果想要查看具体细节，可以点击[这里](https://github.com/Cricin/Folivora/blob/master/sample/src/main/java/cn/cricin/folivora/sample/drawable/WindmillDrawable.java)查看源码 3. 在layout文件中使用自定义drawable，Folivora提供了`drawableName`属性，使用该属性指定需要使用的drawable： ```xml ``` 运行之后的效果： 到这里，Folivora就会为该`View`设置我们指定的drawable了，有人可能就会问了，drawable名字这么长，写起来会不会太复杂了，不用担心，当你敲出drawableName的时候，Folivora会为你自动提示可用的drawable名字的，并且该drawable的自定义属性也会有自动提示。 > 如果我的自定义drawable没有上面指定的构造方法，并且我没办法直接修改该drawable的源码来添加这个构造方法该怎么办呢？ Folivora考虑到了这一点，有些drawable的源码我们没法修改，但是它总会有向外提供设置属性的方法吧？所以，我们提供了一个`DrawableFactory`接口，假设`WindmillDrawable`只有一个无参的构造方法，但是提供了设置各种属性的方法，我们需要让Folivora支持`WindmillDrawable`，可以这样做： ```java Folivora.addDrawableFactory(new Folivora.DrawableFactory() { @Override public Drawable newDrawable(Context context, AttributeSet attrs) { TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.WindmillDrawable); WindmillDrawable d = new WindmillDrawable(); d.setColor0(a.getColor(R.styleable.WindmillDrawable_wdColor0, Color.BLACK)); d.setRotateDegrees(a.getInt(R.styleable.WindmillDrawable_wdRotateDegrees, 0)); ... a.recycle(); return d; } @Override public Class drawableClass() { return WindmillDrawable.class; } }); ``` > 自定义Drawable请注意，如果你的drawable需要获取其他drawable，建议使用`Folivora.getDrawable(Context ctx, TypedArray a, AttributeSet attrs, int attrIndex)`方法获取，这样可以支持获取内嵌的`shape`，当然如果你不需要支持内嵌的`shape`，可以不用这样做。 ### 使用Drawable缓存 在之前的版本中，Folivora会根据view tag中的属性创建drawable，每次都会创建一个新的drawable实例，很浪费资源，现在Folivora支持了drawable的缓存功能(LruCache，大小为128), 使用缓存非常简单，只需要添加`app:drawableId`属性，为drawable指定一个id(string类型，不是android的id类型)即可。Folivora在为view设置drawable的时候，如果drawable在缓存中，会直接从缓存中取。这就带来了一个便利，如果在一个layout文件中，一个drawable被多次使用，只需要在第一次使用的地方编写drawable定义就行了，其他的地方可以直接使用drawableId引用该drawable。 ```xml ``` 建议为需要复用的drawable和经常使用的layout文件中的drawable设置`drawableId`, 以提升性能。 ### 下载示例APK [点击下载](https://raw.githubusercontent.com/Cricin/Folivora/master/sample.apk) ### 编辑layout文件时的预览 > 预览效果

implementation 'cn.cricin:folivora:0.1.0' } ``` - **STEP2** : write down the attribute provided by folivora, tell folivora how to create drawable, prefix of drawables folivora builtin supported are: * shape -> shape * selectror -> selector * layer-list -> layer * level-list -> level * clip -> clip * scale -> scale * inset -> inset * ripple -> ripple * animation -> anim for example, all attributes prefix of a GradientDrawable is shape, like `shapeSolidColor`, `shapeCornerRadius`, IDE will gives you all available attributes after you write down `drawableType` and typed the drawable prefix. > shape let's try to write down some code to introduce how folivora works with the first view above ```xml ``` here are some other supported drawable usages: > layerlist ```xml ``` > levellist ```xml ``` > selector ```xml ``` since 0.0.7，Folivora added support about complicated state selector，use `app:selectorItemXStates` to set state flags，and use `app:selectorItemXDrawable` set corresponding drawable to the states(X can be 0，1，2，3，4)，now we can use the new way to describe drawable above。 ```xml ``` Note：it is recommended to not mixed two selector definitions，just use the new way is better，which is ordered when add in selector by item index, constraint is only support 5 items for now, which is enough for usual selectors. > ripple ```xml ``` much cooler after used ripple drawable, but ripple effect is introduced in lollipop, if the device platform version is lower than lolipop, folivora provided a `RippleFallback` for you, you can provide a substitude drawable if ripple is unavailable, let's try a create a `selector` instead of `ripple`: ```java Folivora.setRippleFallback(new RippleFallback()){ @Override public Drawable onFallback(ColorStateList ripple, Drawable content, Drawable mask, Context ctx){ StateListDrawable sld = new StateListDrawable(); sld.addState(new int[]{android.R.attr.state_pressed}, new ColorDrawable(ripple.getDefaultColor())); sld.addState(new int[0], content); return sld; } } ``` > clip ```xml ``` > inset ```xml ``` > scale ```xml ``` > animation ```xml ``` _Note: Popular IDE's (Android Studio, IntelliJ) will likely mark this as an error despite being correct. You may want to add `tools:ignore="MissingPrefix"` to either the View itself or its parent ViewGroup to avoid this. You'll need to add the tools namespace to have access to this "ignore" attribute. `xmlns:tools=" http://schemas.android.com/tools"`. See https://code.google.com/p/android/issues/detail?id=65176._ - **STEP3** : enable folivora in your app, there are two ways: ```java public class MainActivity extends Activity { @Override protected void attachBaseContext(Context newBase) { super.attachBaseContext(Folivora.wrap(newBase)); } } ``` or ```java public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Folivra.installViewFactory(this); setContentView(R.layout.your_layout_xml_name); } } ``` #### Use nested shape Folivora now support nest shape in drawable, except `animation`, all drawable's child drawable can use `@drawable/xxx`, a color, or one of shape/shape1/shape2/shape3/shape4, you can use this prefix combine with the shape attrs, let's define two round corner shape nested in selector: ```xml ``` effect is: ### Use custom drawable since 0.0.4，Folivora support use custom drawable, makes it easyly to use custom drawables just like custom views，for example, let's write a `WindmillDrawable` which draws a paper windmill： 1. first, write down some attrs we needed for `WindmillDrawable`, just like the way of custom view: ```xml ``` Note: declare-styleable name must equals with the drawable's simple class name, so folivora will support code completion about the custom attrs. 2. Create a `WindmillDrawable`，extends `Drawable`, provide a `public WindmillDrawable(Context ctx, AttributeSet attrs)` constructor，you can retrieve custom attrs here, like this： ```java public WindmillDrawable(Context ctx, AttributeSet attrs) { TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.WindmillDrawable); int count = a.getIndexCount(); for (int i = 0; i < count; i++) { int index = a.getIndex(i); switch (index) { case R.styleable.WindmillDrawable_wdSize: mSize = a.getDimensionPixelSize(index, mSize); break; case R.styleable.WindmillDrawable_wdColor0: mColors[0] = a.getColor(index, mColors[0]); break; case R.styleable.WindmillDrawable_wdColor1: mColors[1] = a.getColor(index, mColors[1]); break; ... default://no-op unexpected attr index break; } } a.recycle(); } ``` this is samilar to costom `View`，the main purpose is to add a constructor that takes a `Context` and `AttributeSet` as parameter, other code is emitted here, for more details，[click](https://github.com/Cricin/Folivora/blob/master/sample/src/main/java/cn/cricin/folivora/sample/drawable/WindmillDrawable.java) to view source code 3. use `WindmillDrawable` in your layout files，Folivora provided a `drawableName` attr，you can declare the drawable name here： ```xml ``` at runtime, the drawable is created by folivora and get worked： you may ask, the drawable's name is to long to remember, it's difficult to write down，don't worry at it，folivora will gives the candidate of custom drawables if you typed down drawableName attr, attrs about the specific drawable is also will have code completion support. > Support of custom drawables do not have the constructor which recieves `Context` and `AttributeSet` as parameter Folivora take concerned it, source code of some drawables is not permited to modify, so，we provided a `DrawableFactory` interface，assume `WindmillDrawable` only have a constructor takes no parameter，but provided some methods to modify it, to support `WindmillDrawable`，we can do this： ```java Folivora.addDrawableFactory(new Folivora.DrawableFactory() { @Override public Drawable newDrawable(Context context, AttributeSet attrs) { TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.WindmillDrawable); WindmillDrawable d = new WindmillDrawable(); d.setColor0(a.getColor(R.styleable.WindmillDrawable_wdColor0, Color.BLACK)); d.setRotateDegrees(a.getInt(R.styleable.WindmillDrawable_wdRotateDegrees, 0)); ... a.recycle(); return d; } @Override public Class drawableClass() { return WindmillDrawable.class; } }); ``` > If you are using custom drawable，and your drawable contains other drawables, it is recommended to use `Folivora.getDrawable(Context ctx, TypedArray a, AttributeSet attrs, int attrIndex)` to get a drawable, this method will take care about nested shape creation, also you can do not follow this tip if you do not need nested shape support。 ### Drawable caches In previous releases，Folivora will create drawables according to attrs from view tag, a new instance is created for per view, which is waste resources, now Folivora supported drawable caching(LruCache，max = 128), usage is very simple，just add `app:drawableId` attr，set a id(string type，not android's id type) to drawable is ok。Folivora will lookup cache to find a cached drawable, which means，if in a layout.xml，a drawable should be referenced multi places, define it at first occurrence, then at other place, use the same `drawableId` to reference this drawable. ```xml ``` It is recommended to set `drawableId` to drawable which is reusable or inside a frequently used layout files, which makes a better performance. ### Download Sample APK [Click to download](https://raw.githubusercontent.com/Cricin/Folivora/master/sample.apk) ### Design
