使用

添加依赖

  1. 在工程的build.gradle文件中添加:
buildscript {
    repositories {
        maven { url "https://jitpack.io" } // 必须添加
    }
    dependencies {
        ...
        classpath 'com.hujiang.aspectjx:gradle-android-plugin-aspectjx:2.0.10' // 如果不使用AutoPlugin可以不添加
    }
    allprojects {
        maven { url "https://jitpack.io" } // 必须添加
    }
}
  1. 如需使用 AutoPlugin ,在项目 appbuild.gradle 文件中添加:
apply plugin: 'android-aspectjx' 

android {
    ...
}
  1. 在项目 appbuild.gradle 文件中添加:
dependencies {
    // 依赖的反射库
    implementation 'com.github.CoderAlee:Reflex:1.2.0'
    // 核心库
    implementation 'com.github.CoderAlee.PaintedSkin:painted-skin:TAG'
    implementation 'com.github.CoderAlee.PaintedSkin:standard-plugin:TAG'
    // StandardPlugin 与 AutoPlugin 只需添加一个
    annotationProcessor 'com.github.CoderAlee.PaintedSkin:auto-plugin:TAG'
    implementation 'com.github.CoderAlee.PaintedSkin:auto-plugin:TAG'
    //如果项目中的 ConstraintLayout 需要换肤则引入
    implementation 'com.github.CoderAlee.PaintedSkin:constraintlayout-compat:TAG'
    // 需要替换字体库时引入
    implementation 'com.github.CoderAlee.PaintedSkin:typeface-plugin:TAG'
    ...
}

运行配置

PaintedSkin 支持三种换肤模式:
public final class App extends Application {
    static {
        Config.getInstance().setSkinMode(Config.SkinMode.REPLACE_ALL);
    }
}
PaintedSkin 支持调试模式与严格模式:
public final class App extends Application {
    static {
         Config.getInstance().setEnableDebugMode(false);
         Config.getInstance().setEnableStrictMode(false);
    }
}
PaintedSkin 支持性能优先与体验优先:
public final class App extends Application {
    static {
         Config.getInstance().setPerformanceMode(Config.PerformanceMode.PERFORMANCE_PRIORITY);
          Config.getInstance().setPerformanceMode(Config.PerformanceMode.EXPERIENCE_FIRST);
    }
}

插件使用

StandardPlugin 使用:
public final class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        WindowManager.getInstance().init(this,new OptionFactory());
    }
}
final class OptionFactory implements IOptionFactory {
    @Override
    public int defaultTheme() {
        return 0;
    }

    @Override
    public IThemeSkinOption requireOption(int theme) {
        switch (theme) {
            case 1:
                return new NightOption();
            default:
                return null;
        }
    }
}
AutoPlugin 不再需要开发人员调用初始化代码,只需要在实现了 IOptionFactory 接口的实现类上添加注解 @Skin 即可:
@Skin
public final class OptionFactory implements IOptionFactory {
    @Override
    public int defaultTheme() {
        return 0;
    }

    @Override
    public IThemeSkinOption requireOption(int theme) {
        switch (theme) {
            case 1:
                return new NightOption();
            default:
                return null;
        }
    }
}

主题配置

class NightOption implements IThemeSkinOption {

    @Override
    public LinkedHashSet<String> getStandardSkinPackPath() {
        LinkedHashSet<String> pathSet = new LinkedHashSet<>();
        pathSet.add("/sdcard/night.skin");
        return pathSet;
    }
}

换肤

ThemeSkinService.getInstance().switchThemeSkin(int theme);

皮肤包构建

  1. 新建 Android application 工程。

  2. 皮肤工程包名不能和宿主应用包名相同。

  3. 将需要换肤的资源放置于res对应目录下

    • 如果想要替换 Button 文字颜色,在 apk 的 res/values/colors.xml 的目录下有如下资源:

      <color name="textColor">#FFFFFFFF</color>

      在皮肤包对应 res/values/colors.xml 的目录下有如下资源:

      <color name="textColor">#FF000000</color>
    • 如果想要替换 Button 背景图片,在 apk 中有 res/mipmap/bg_button.png ,在皮肤包中 res/mipmap/bg_button.png

  4. 在皮肤包工程的 build.gradle 文件中添加:

    applicationVariants.all { variant ->
        variant.outputs.all { output ->
            outputFileName = "xxx.skin"
        }
    }

动态创建View换肤

核心接口 WindowManager.getInstance().getWindowProxy(getContext()).addEnabledThemeSkinView(View,SkinElement);

TextView textView = new TextView(getContext());
textView.setTextColor(getResources().getColor(R.color.textColor));
textView.setText("动态创建View参与换肤");
WindowManager.getInstance().getWindowProxy(getContext()).addEnabledThemeSkinView(textView, new SkinElement("textColor", R.color.textColor));
layout.addView(textView);

进阶用法

拦截View创建过程

ThemeSkinService.getInstance().getCreateViewInterceptor().add(new LayoutInflater.Factory2() {
    @Nullable
    @Override
    public View onCreateView(@Nullable View parent, @NonNull String name, @NonNull Context context, @NonNull AttributeSet attrs) {
        return onCreateView(name, context, attrs);
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull String name, @NonNull Context context, @NonNull AttributeSet attrs) {
        if (TextUtils.equals(name,"TextView")){
            return new Button(context, attrs);
        }
        return null;
    }
});

通过拦截 View 的创建过程其实可以实现很多骚操作,比如上面这段代码就可以将全局的 TextView 替换成 Button 。这比在 XML 中一个一个修改要快捷方便的多。其中 Google 就是通过这种方式将 Button 替换为 AppCompatButton 。 AppCompatDelegate 也是同样的技术方案。

自定义 View 、三方库 View 换肤

当自定义View或使用的三方库View中有自定义属性需要换肤时:

  1. 实现IThemeSkinExecutorBuilder 接口,用于解析支持换肤属性并创建对应属性的换肤执行器。可以参考框架内自带的DefaultExecutorBuilder:
@RestrictTo(RestrictTo.Scope.LIBRARY)
public final class DefaultExecutorBuilder implements IThemeSkinExecutorBuilder {
    /**
    * 换肤支持的属性 背景
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_BACKGROUND = "background";
    /**
    * 换肤支持的属性 前景色
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_FOREGROUND = "foreground";
    /**
    * 换肤支持的属性 字体颜色
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_TEXT_COLOR = "textColor";
    /**
    * 换肤支持的属性 暗示字体颜色
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_TEXT_COLOR_HINT = "textColorHint";
    /**
    * 换肤支持的属性 选中时高亮背景颜色
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_TEXT_COLOR_HIGH_LIGHT = "textColorHighlight";
    /**
    * 换肤支持的属性 链接的颜色
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_TEXT_COLOR_LINK = "textColorLink";
    /**
    * 换肤支持的属性 进度条背景
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_PROGRESS_DRAWABLE = "progressDrawable";
    /**
    * 换肤支持的属性 ListView分割线
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_LIST_VIEW_DIVIDER = "divider";
    /**
    * 换肤支持的属性 填充内容
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_SRC = "src";
    /**
    * 换肤支持的属性 按钮背景
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public static final String ATTRIBUTE_BUTTON = "button";
    private static final Map<Integer, String> SUPPORT_ATTR = new HashMap<>();

    static {
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_background, ATTRIBUTE_BACKGROUND);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_foreground, ATTRIBUTE_FOREGROUND);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_textColor, ATTRIBUTE_TEXT_COLOR);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_textColorHint, ATTRIBUTE_TEXT_COLOR_HINT);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_textColorHighlight, ATTRIBUTE_TEXT_COLOR_HIGH_LIGHT);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_textColorLink, ATTRIBUTE_TEXT_COLOR_LINK);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_progressDrawable, ATTRIBUTE_PROGRESS_DRAWABLE);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_divider, ATTRIBUTE_LIST_VIEW_DIVIDER);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_src, ATTRIBUTE_SRC);
        SUPPORT_ATTR.put(R.styleable.BasicSupportAttr_android_button, ATTRIBUTE_BUTTON);
    }

    /**
    * 解析支持换肤的属性
    *
    * @param context      {@link Context}
    * @param attributeSet {@link AttributeSet}
    * @return {@link SkinElement}
    */
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    @Override
    public Set<SkinElement> parse(@NonNull Context context, @NonNull AttributeSet attributeSet) {
        TypedArray typedArray = context.obtainStyledAttributes(attributeSet, R.styleable.BasicSupportAttr);
        if (null == typedArray) {
            return null;
        }
        Set<SkinElement> elementSet = new HashSet<>();
        try {
            for (Integer key : SUPPORT_ATTR.keySet()) {
                try {
                    if (typedArray.hasValue(key)) {
                        elementSet.add(new SkinElement(SUPPORT_ATTR.get(key), typedArray.getResourceId(key, -1)));
                    }
                } catch (Throwable ignored) {
                }
            }
        } catch (Throwable ignored) {
        } finally {
            typedArray.recycle();
        }
        return elementSet;
    }

    /**
    * 需要换肤执行器
    *
    * @param view    需要换肤的View
    * @param element 需要执行的元素
    * @return {@link ISkinExecutor}
    */
    @Override
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public ISkinExecutor requireSkinExecutor(@NonNull View view, @NonNull SkinElement element) {
        return BasicViewSkinExecutorFactory.requireSkinExecutor(view, element);
    }

    /**
    * 是否支持属性
    *
    * @param view     View
    * @param attrName 属性名称
    * @return true: 支持
    */
    @Override
    @RestrictTo(RestrictTo.Scope.LIBRARY)
    public boolean isSupportAttr(@NonNull View view, @NonNull String attrName) {
        return SUPPORT_ATTR.containsValue(attrName);
    }
}
  1. 继承BaseSkinExecutor 提供对应属性的换肤执行器:
public class ViewSkinExecutor<T extends View> extends BaseSkinExecutor<T> {

    public ViewSkinExecutor(@NonNull SkinElement fullElement) {
        super(fullElement);
    }

    @Override
    protected void applyColor(@NonNull T view, @NonNull ColorStateList colorStateList, @NonNull String attrName) {
        switch (attrName) {
            case ATTRIBUTE_BACKGROUND:
            case ATTRIBUTE_FOREGROUND:
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                    applyDrawable(view, new ColorStateListDrawable(colorStateList), attrName);
                } else {
                    applyColor(view, colorStateList.getDefaultColor(), attrName);
                }
                break;
            default:
                break;
        }
    }

    @Override
    protected void applyColor(@NonNull T view, int color, @NonNull String attrName) {
        switch (attrName) {
            case ATTRIBUTE_BACKGROUND:
                view.setBackgroundColor(color);
                break;
            case ATTRIBUTE_FOREGROUND:
                applyDrawable(view, new ColorDrawable(color), attrName);
                break;
            default:
                break;
        }
    }

    @Override
    protected void applyDrawable(@NonNull T view, @NonNull Drawable drawable, @NonNull String attrName) {
        switch (attrName) {
            case ATTRIBUTE_BACKGROUND:
                view.setBackground(drawable);
                break;
            case ATTRIBUTE_FOREGROUND:
                view.setForeground(drawable);
                break;
            default:
                break;
        }
    }
}
  1. 将自定义的ThemeSkinExecutorBuilder添加到框架中:
ThemeSkinService.getInstance().addThemeSkinExecutorBuilder(xxx);

ConstraintLayout 换肤兼容包使用

public final class App extends Application {
    static {
        ConstraintLayoutCompat.init();
    }
}

TypefacePlugin 使用

public final class App extends Application {
    static {
        TypefacePlugin.init();
    }

    @Override
    public void onCreate() {
        super.onCreate();
       TypefacePlugin.getInstance().setEnable(true).switchTypeface(Typeface);
    }
}

混淆配置

项目需要混淆编译时,请在 proguard-rules.pro 中添加如下规则

-keep class org.alee.reflex.** { *; }
-keep class org.alee.component.skin.** { *; }
