最近在作一个android player项目，想要默认使用android的internal资源，好比： java

com.android.internal.R.layout.media_controller

可是，直接使用会报编译错误：

com.android.internal.R does not exist android

You cannot import the internal android class, as the internal.R class isn't visible.

可是能够经过其余的方式来访问，以下： git

int mediaControllerId = Resources.getSystem().getIdentifier("media_controller", "layout", "android");

View layout = ((LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(mediaControllerId, this);

同理，能够访问：

mPrevButton = (ImageButton) layout.findViewById(Resources.getSystem().getIdentifier("prev","id", "android"));
mProgress = (ProgressBar) layout.findViewById(Resources.getSystem().getIdentifier("mediacontroller_progress","id", "android"));
mPauseButton = (ImageButton) layout.findViewById(Resources.getSystem().getIdentifier("pause","id", "android"));

getIdentifier的使用方式以下，会返回name对应的id， github

Resources.getSystem().getIdentifier(name, defType, defPackage)

而上述name/defType/defPackage如何获得？能够从源码中得到相应的信息 this
