Custom android AnalogClock from original AnalogClock class not working

Custom android AnalogClock from original AnalogClock class not working

I want to make a custom AnalogClock class using source code of AnalogClock by android developers that is available in the internet.
I want to make the clock set the time that I want, not the current time. I didn't find a clear example on how to do it so maybe this post will be useful. After copying source code to new file, I get some errors. Below is the original source code of AnalogClock:

!!Error mContext -> change to context
    public AnalogClock(Context context, AttributeSet attrs,
                       int defStyle) {
        super(context, attrs, defStyle);
        Resources r = mContext.getResources();
!!Error com.android.internal.R cannot be resolved. I found a solution to this problem with
mDial = r.getDrawable(Resources.getSystem().getIdentifier("clock_dial","drawable", "android"));
And same for other lines just changing name and either drawable or styleable.
vvvv----But I still have a problem with the below code.
        TypedArray a =
                context.obtainStyledAttributes(
                        attrs, com.android.internal.R.styleable.AnalogClock, defStyle, 0);
^^^^----I don't have idea how to change it and make it work
        mDial = a.getDrawable(com.android.internal.R.styleable.AnalogClock_dial);
        if (mDial == null) {
            mDial = r.getDrawable(com.android.internal.R.drawable.clock_dial);
        }
