Question

I need to see implementation of getText(int resId) method. This method is defined as final in abstract class Context.java and I’ve searched implementation in ContextWrapper.java and ContextThemeWrapper.java but I could’t find any implementation. Can somebody post a ling to this method implementation? I’ve looked on netmite.com for classes implementations. Thanks

It is implementation of getText() in Context.java. Class is abstract but it has implementation of this method.

public final CharSequence getText(int resId) {
    return getResources().getText(resId);
}

Implementation of Resources.getText():

public CharSequence getText(int id) throws NotFoundException {
    CharSequence res = mAssets.getResourceText(id);
    if (res != null) {
        return res;
    }
    throw new NotFoundException("String resource ID #0x"
                                + Integer.toHexString(id));
}

Implementation of AssetManager.getResourceText():

final CharSequence getResourceText(int ident) {
    synchronized (this) {
        TypedValue tmpValue = mValue;
        int block = loadResourceValue(ident, (short) 0, tmpValue, true);
        if (block >= 0) {
            if (tmpValue.type == TypedValue.TYPE_STRING) {
                return mStringBlocks[block].get(tmpValue.data);
            }
            return tmpValue.coerceToString();
        }
    }
    return null;
}

Upd: As mentioned by @zapl loadResourceValue() is native and can be found in android_util_AssetManager.cpp.
