从另一个APK加载资源(布局) [英] Load resource (layout) from another apk

问题描述

我想知道是否可以从另一个apk加载布局xml文件.我知道如何访问另一个应用程序资源，但是我不确定如何加载xml(如果可能的话).

I am wondering if it is possible to load a layout xml file from another apk. I know how to get access to another applications resources, but i am unsure how to load an xml if its even possible.

如果我想使用版式充气工具将该版式设置为视图，是否必须解析xml?

Would I have to parse the xml if I wanted to set that layout as a view using layout inflater?

按以下步骤排序...

Sort of like these steps...

1. 使用XmlPullParser.setInput来加载" XML文件
2. 将其转换为AttributeSet
3. 从此AttributeSet创建视图
4. 在活动"中使用setContentView(View)

我猜我在问什么，这有可能吗?就像我说的，我知道如何访问资源.但是我将如何访问xml布局?

I guess what i am asking, is this even possible? Like I said, i know how to access resources. But how would i access the layout xml?

谢谢！

推荐答案

我设法拉出了版面，并将其添加到我的viewflipper中，但是在这里它被加载为空白.

I managed to pull the layouts, and i add it to my viewflipper, however, there it is loaded as blank.

Resources packageResources;
Context packageContext;
try
{   
    packageResources = pm.getResourcesForApplication(packageName);
    packageContext = this.createPackageContext(packageName,  Context.CONTEXT_INCLUDE_CODE + Context.CONTEXT_IGNORE_SECURITY);                
}
catch(NameNotFoundException excep)
{
    // the package does not exist. move on to see if another exists.
}

Class layoutClass;
try
{
   // using reflection to get the layout class inside the R class of the package
   layoutClass = packageContext.getClassLoader().loadClass(packageName + ".R$layout");
}
catch (ClassNotFoundException excep1)
{
   // Less chances that class won't be there.
}

for( Field layoutID : layoutClass.getFields() )
{
   try
   {
       int id = layoutID.getInt(layoutClass);
       XmlResourceParser xmlResourceLayout = packageResources.getLayout(id);

       View v = new View(this, Xml.asAttributeSet(xmlResourceLayout));

       this.viewFlipper.addView(v);                 
    }
    catch (Exception excep)
    {
        continue;
    }
}

我没有任何错误，并且我进行了调试和检查.布局ID是正确的.但是，在我的viewFlipper中，它只是空白.我找不到警告或错误.

I get no errors, and i debugged and checked. The layout IDs are correct. However, in my viewFlipper its just blank. No warnings or errors i can find.
