skin-loader框架的換膚是通過插件化的形式替換資源文件，實現換膚效果。好處是可以在線更新皮膚換膚

android-skin-loader源碼

Demo樣例

流程

整個框架大概的流程是加載皮膚包，找到被標記的控件，通過自定義的Factory工程過濾掉其他控件，使用皮膚包中的資源文件更新被標記的ui。

使用操作

1、導入android-skin-loader框架包 androidStudio File->new->import Module選擇android-skin-loader 項目右鍵->open Module Setting->app中加載依賴android-skin-loader庫

2、在MyApplication 初始化框架

SkinManager.getInstance().init(this);SkinManager.getInstance().load();

3、需要換膚的activity需要繼承skin-loader中的BaseActivity 需要換膚的控件添加skin:enable=”true”，控件xml添加命名空間xmlns:skin=”http://schemas.android.com/android/skin”

4、準備需要替換的color或drawable同名的資源文件包將其打包，重命名以.skin結尾 本地測試可以使用adb命令將.skin包放在sdcard adb push 文件目錄/test.skin /sdcard

樣例代碼

xml文件，使用databinding，不知道的自行百度

<?xml version='1.0' encoding='utf-8'?><layout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:skin='http://schemas.android.com/android/skin'> <LinearLayout android:layout_width='match_parent' android:layout_height='match_parent' android:orientation='vertical'> <LinearLayout android:layout_width='match_parent' android:layout_height='wrap_content' android:orientation='horizontal'> <Button android: android:layout_width='wrap_content' android:layout_height='wrap_content' android:textColor='@color/text_color' android:background='@color/button_background' skin:enable='true' android:text='默認皮膚'/> <Button android: android:layout_width='wrap_content' android:layout_height='wrap_content' android:layout_marginLeft='20dp' android:textColor='@color/text_color' android:background='@color/button_background' skin:enable='true' android:text='更改皮膚'/> <Button android: android:layout_width='wrap_content' android:layout_height='wrap_content' android:layout_marginLeft='20dp' android:textColor='@color/text_color' android:background='@color/button_background' skin:enable='true' android:text='動態添加布局'/> </LinearLayout> <TextView android:layout_width='match_parent' android:layout_height='wrap_content' android:textColor='@color/text_color' android:text='文字文字文字文字文字文字' skin:enable='true' /> <ImageView android:layout_width='wrap_content' android:layout_height='wrap_content' android:src='http://www.cgvv.com.cn/bcjs/@drawable/skin' skin:enable='true'/> <LinearLayout android: android:layout_width='match_parent' android:layout_height='wrap_content' skin:enable='true' android:orientation='vertical'> </LinearLayout> </LinearLayout></layout>

public class SkinChangeAct extends BaseActivity{ private ActivitySkinchangeBinding binding; //skin包名 private String SKIN_NAME = 'test.skin'; //skin皮膚包的路徑 private String SKIN_DIR = Environment.getExternalStorageDirectory()+ File.separator+SKIN_NAME; @Override public void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); binding = DataBindingUtil.setContentView(this, R.layout.activity_skinchange); //更換皮膚 binding.btnChangeSkin.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { File skin = new File(SKIN_DIR); if(skin == null || !skin.exists()){ Toast.makeText(getApplicationContext(), '請檢查' + SKIN_DIR + '是否存在', Toast.LENGTH_SHORT).show(); return; } SkinManager.getInstance().load(skin.getAbsolutePath(), new ILoaderListener() { @Override public void onStart() { System.out.println('start'); } @Override public void onSuccess() { System.out.println('onSuccess'); } @Override public void onFailed() { System.out.println('onFailed'); } }); } }); //恢復默認皮膚 binding.btnDefault.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { SkinManager.getInstance().restoreDefaultTheme(); } }); //動態加載控件 binding.btnAdd.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { dynamicAddTextView(); } }); } /**動態添加textview*/ private void dynamicAddTextView() { TextView textView = new TextView(this); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); params.addRule(RelativeLayout.CENTER_IN_PARENT); textView.setLayoutParams(params); textView.setTextColor(SkinManager.getInstance().getColor(R.color.text_color)); textView.setText('hellohello'); textView.setTextSize(28); //將動態添加的布局也更換皮膚，否則之前添加的不能更改 List<DynamicAttr> mDanamicAttr = new ArrayList<DynamicAttr>(); mDanamicAttr.add(new DynamicAttr(AttrFactory.TEXT_COLOR,R.color.text_color)); dynamicAddView(textView,mDanamicAttr); binding.addLayout.addView(textView); }}

資源文件color.xml

<?xml version='1.0' encoding='utf-8'?><resources> <color name='colorPrimary'>#3F51B5</color> <color name='colorPrimaryDark'>#303F9F</color> <color name='colorAccent'>#FF4081</color> <color name='text_color'>#ff0000</color> <color name='button_background'>#00ff00</color></resources>

skin皮膚包中的資源文件color.xml

<?xml version='1.0' encoding='utf-8'?><resources> <color name='colorPrimary'>#3F51B5</color> <color name='colorPrimaryDark'>#303F9F</color> <color name='colorAccent'>#FF4081</color> <color name='text_color'>#ffff00</color> <color name='button_background'>#00ffff</color></resources>

對比一下，只是更改了數值，名字相同。

框架迭代，增加功能

android-skin-loader框架是沒有對于src屬性的修改，案例中使用imageView模擬了src的更改。 在AttrFactory中增加對于src的支持

public class AttrFactory { public static final String BACKGROUND = 'background'; public static final String TEXT_COLOR = 'textColor'; public static final String LIST_SELECTOR = 'listSelector'; public static final String DIVIDER = 'divider'; //增加src屬性 public static final String SRC='http://www.cgvv.com.cn/bcjs/src'; public static SkinAttr get(String attrName, int attrValueRefId, String attrValueRefName, String typeName){ SkinAttr mSkinAttr = null; System.out.println('attrName='+attrName); if(BACKGROUND.equals(attrName)){ mSkinAttr = new BackgroundAttr(); }else if(TEXT_COLOR.equals(attrName)){ mSkinAttr = new TextColorAttr(); }else if(LIST_SELECTOR.equals(attrName)){ mSkinAttr = new ListSelectorAttr(); }else if(DIVIDER.equals(attrName)){ mSkinAttr = new DividerAttr(); }else if(SRC.equals(attrName)){ //自定義加載src mSkinAttr =new SrcAttr(); }else{ return null; } mSkinAttr.attrName = attrName; mSkinAttr.attrValueRefId = attrValueRefId; mSkinAttr.attrValueRefName = attrValueRefName; mSkinAttr.attrValueTypeName = typeName; return mSkinAttr; } /** * Check whether the attribute is supported * @param attrName * @return true : supported <br> * false: not supported */ public static boolean isSupportedAttr(String attrName){ if(BACKGROUND.equals(attrName)){ return true; } if(TEXT_COLOR.equals(attrName)){ return true; } if(LIST_SELECTOR.equals(attrName)){ return true; } if(DIVIDER.equals(attrName)){ return true; } //支持src if(SRC.equals(attrName)){ return true; } return false; }}

srcAttr繼承SkinAttr定義加載src

public class SrcAttr extends SkinAttr{ @Override public void apply(View view) { if(view instanceof ImageView){ ImageView imageView = (ImageView) view; if(RES_TYPE_NAME_COLOR.equals(attrValueTypeName)){ imageView.setImageResource(SkinManager.getInstance().getColor(attrValueRefId)); }else if(RES_TYPE_NAME_DRAWABLE.equals(attrValueTypeName)){ Drawable bg = SkinManager.getInstance().getDrawable(attrValueRefId); imageView.setImageDrawable(bg); } } }}

各種控件的支持都可以自己添加。
