使用DexClassLoader加载apk

要加载apk中的资源：

[java] view
plaincopy





protected void loadResources() {

try {

AssetManager assetManager = AssetManager.class.newInstance();

Method addAssetPath = assetManager.getClass().getMethod("addAssetPath", String.class);

addAssetPath.invoke(assetManager, mDexPath);

mAssetManager = assetManager;

} catch (Exception e) {

e.printStackTrace();

}

Resources superRes = super.getResources();

mResources = new Resources(mAssetManager, superRes.getDisplayMetrics(),

superRes.getConfiguration());

mTheme = mResources.newTheme();

mTheme.setTo(super.getTheme());

}

说明：加载的方法是通过反射，通过调用AssetManager中的addAssetPath方法，我们可以将一个apk中的资源加载到Resources中，由于addAssetPath是隐藏api我们无法直接调用，所以只能通过反射，下面是它的声明，通过注释我们可以看出，传递的路径可以是zip文件也可以是一个资源目录，而apk就是一个zip，所以直接将apk的路径传给它，资源就加载到AssetManager中了，然后再通过AssetManager来创建一个新的Resources对象，这个对象就是我们可以使用的apk中的资源了，这样我们的问题就解决了。

[java] view
plaincopy





/**

* Add an additional set of assets to the asset manager. This can be

* either a directory or ZIP file. Not for use by applications. Returns

* the cookie of the added asset, or 0 on failure.

* {@hide}

*/

public final int addAssetPath(String path) {

int res = addAssetPathNative(path);

return res;

}

其次是要实现那两个抽象方法

[java] view
plaincopy





@Override

public AssetManager getAssets() {

return mAssetManager == null ? super.getAssets() : mAssetManager;

}

@Override

public Resources getResources() {

return mResources == null ? super.getResources() : mResources;

}
