skin-loader-lib（动态加载本地皮肤包进行换肤）开源库

    原理：打apk资源包，采用覆盖（资源名称覆盖）的形式替换主题 ，一套主题对应一个apk资源包
    多主题可以将多个apk资源包放在同一目录下，遍历显示出来由用户选择 （将生成的apk文件改为(.skin)文件)
    BMLauncher项目中将faacy.skin（资源文件）放到了assets中 copy到sdcard中
    不支持 mipmap，需要将 mipmap 中的文件移动到 drawable 中 

使用说明
1.下载Android-Skin-Loader

地址：https://github.com/fengjundev/Android-Skin-Loader

    android-skin-loader-lib 将依赖库导入项目
    android-skin-loader-skin 资源皮肤包 demo （将生成的apk文件改为(.skin)文件)

使用gradle build android-skin-loader-skin工程后即可在skin-package目录下取皮肤包（修改脚本中def skinName = "BlackFantacy.skin"换成自己想要的皮肤名）
2.在Application中进行初始化

public class SkinApplication extends Application {
		public void onCreate() {
			super.onCreate();
			// Must call init first 
			SkinManager.getInstance().init(this);
			SkinManager.getInstance().load();
			}
	}

3.在布局文件中标识需要换肤的View

              ...
		xmlns:skin="http://schemas.android.com/android/skin"
		...
		  <TextView
		     ...
		     skin:enable="true" 
		     ... />

4. 继承BaseActivity或者BaseFragmentActivity作为BaseActivity进行开发，Fragment 继承 BaseFragment 进行开发
5. 从.skin文件中设置皮肤

String SKIN_NAME = "BlackFantacy.skin";
String SKIN_DIR = Environment.getExternalStorageDirectory() + File.separator + SKIN_NAME;
File skin = new File(SKIN_DIR);
SkinManager.getInstance().load(skin.getAbsolutePath(),
				new ILoaderListener() {
					@Override
					public void onStart() {
					}

					@Override
					public void onSuccess() {
					}

					@Override
					public void onFailed() {
					}
				});

6. 重设默认皮肤

SkinManager.getInstance().restoreDefaultTheme();

7. 对代码中创建的View的换肤支持

public interface IDynamicNewView {
	void dynamicAddView(View view, List<DynamicAttr> pDAttrs);
}

动态创建View后，调用dynamicAddView方法注册该View至皮肤映射表即可

private void dynamicAddTitleView() {
		TextView textView = new TextView(getActivity());
		textView.setText("Small Article (动态new的View)");
		RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
		param.addRule(RelativeLayout.CENTER_IN_PARENT);
		textView.setLayoutParams(param);
		textView.setTextColor(getActivity().getResources().getColor(R.color.color_title_bar_text));
		textView.setTextSize(20);
		titleBarLayout.addView(textView);
		
		List<DynamicAttr> mDynamicAttr = new ArrayList<DynamicAttr>();
		mDynamicAttr.add(new DynamicAttr(AttrFactory.TEXT_COLOR, R.color.color_title_bar_text));
		dynamicAddView(textView, mDynamicAttr);
	}

8. 在代码中setImgeView

 mAudioBtn.setImageDrawable(SkinManager.getInstance().getDrawable(R.drawable.ic_local_mode));
titleText.setTextColor(SkinManager.getInstance().getColor(R.color.ic_local_mode));

9. 在android-skin-loader-lib库中扩展属性

添加scr属性 AttrFactory.java

public class AttrFactory {
	public static final String SRC= "src";

	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";
	
	public static SkinAttr get(String attrName, int attrValueRefId, String attrValueRefName, String typeName){
		
		SkinAttr mSkinAttr = null;
		
		if (BACKGROUND.equals(attrName) || SRC.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{
			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 (SRC.equals(attrName)) {
			return true;
		}
		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;
		}
		return false;
	}
}

BackgroundAttr .java

public class BackgroundAttr extends SkinAttr {

	@Override
	public void apply(View view) {
		
		if(RES_TYPE_NAME_COLOR.equals(attrValueTypeName)){
			view.setBackgroundColor(SkinManager.getInstance().getColor(attrValueRefId));
			Log.i("attr", "_________________________________________________________");
			Log.i("attr", "apply as color");
		}else if(RES_TYPE_NAME_DRAWABLE.equals(attrValueTypeName)){
			Drawable bg = SkinManager.getInstance().getDrawable(attrValueRefId);
			if(view instanceof ImageView){
				((ImageView)view).setImageDrawable(bg);
			}else{
				view.setBackground(bg);
			}
			Log.i("attr", "_________________________________________________________");
			Log.i("attr", "apply as drawable");
			Log.i("attr", "bg.toString()  " + bg.toString());

			Log.i("attr", this.attrValueRefName + " 是否可变换状态? : " + bg.isStateful());
		}
	}
}
