皮肤切换

  皮肤切换

思路：皮肤切换要两个包：皮肤包   和apk（主包）
当在设置中点击切换时  就会读取 皮肤包内容，从而更换资源的Context对象，并利用了观察者模式 切换所有的activity。从而实现皮肤切换。 

/**

* 如果设置控件皮肤  那么调用此方法

* 

* @param context 当前资源上下文对象  context

* @param name   当前控件的id名

* @param resType 当前切换皮肤的控件的切换类型，color 还是drawble

* @param view  当前切换皮肤的控件

* @param viewType 当前切换的是背景还是文字   0 :背景      1：文字

*/

public  static  void   setElementSkin(Context context ,View view ,String name,String resType,int viewType){

int i=0;

//当前引用资源包名(主包名)

String skinPackage = context.getPackageName();

if(skinPackage!=null){

//主包名

String xctPackageName =SkinManagerObservable.getInstance().getmContext().getPackageName();

//String xctPackageName = this.getPackageName();

//引用主包资源

if(skinPackage.equals(xctPackageName)){

Resources resources = context.getResources();

i  = resources.getIdentifier(name, resType, context.getPackageName());

setSkin(view,resType,viewType,i,resources);

}else {

//引用资源包

Resources resources = context.getResources();

i = resources.getIdentifier(name, resType, context.getPackageName());

if(i!=0){

setSkin(view,resType,viewType,i,resources);

}else {//如果资源包没有找到资源  的情况,从主包资源找

Resources mainPackageRes = SkinManagerObservable.getInstance().getmContext().getResources();

int id = mainPackageRes.getIdentifier(name, resType, SkinManagerObservable.getInstance().getmContext().getPackageName());

/**

}else {

throw new IllegalArgumentException("控件"+view.toString()+"不能设置textcolor 属性");

}

}

}else if("drawable".equals(resType)){

view.setBackgroundDrawable(resources.getDrawable(id));

}

}

/**

* 获取控件的id (区别于切换皮肤)

* 如果是初始化控件 调用此方法

* @param name

* @param resType

* @return

*/

public static   int getElementID(String name,String resType){

Resources mainPackageRes = SkinManagerObservable.getInstance().getmContext().getResources();

Resources skinPackageRes = SkinManagerObservable.getInstance().getrContext().getResources();

int id = 0;

if("id".equals(resType)||"layout".equals(resType)||"string".equals(resType)||"style".equals(resType)){

id = mainPackageRes.getIdentifier(name, resType, SkinManagerObservable.getInstance().getmContext().getPackageName());

}else /*("drawable".equals(resType) || "color".equals(resType) || "string".equals(resType))*/{

id = skinPackageRes.getIdentifier(name, resType, SkinManagerObservable.getInstance().getrContext().getPackageName());

if(id==0){

id = mainPackageRes.getIdentifier(name, resType, SkinManagerObservable.getInstance().getmContext().getPackageName());

}

}

return id;

}



注：activity中的控件获取时将不再使用R.id.xxx或者 R.layout.xxx之类。而采用根据id名称来获取id. (见上面方法)
如：
        setContentView(getElementID("xct_lthj_quotrefreshrate_portrait", "layout");
        buy_price_parent = (LinearLayout) findViewById(getElementID("xct_lthj_mt_entrust_buy_rela_price_parent", "id");
        getElementID("xct_lthj_color_font_red", "color");
        getElementID("xct_lthj_draw_lview_bg", "drawable");

android中调起评分控件

Uri uri = Uri.parse("market://details?id="+getPackageName());  
Intent intent = new Intent(Intent.ACTION_VIEW,uri);  
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
startActivity(intent);
