Implementing a custom view and a ScrollView?

Here is what I don't understand:

    HorizontalScrollView scroll = new HorizontalScrollView(this);       
    scroll.setLayoutParams(new LayoutParams(getResources().getInteger(R.integer.dim_hand_width), getResources().getInteger(R.integer.dim_hand_height)));

    HandLayout = new LinearLayout(this);
    HandLayout.setOrientation(LinearLayout.HORIZONTAL);
    HandLayout.setBackgroundColor(getResources().getColor(R.color.bg_hand));
    HandLayout.setLayoutParams(new LayoutParams(getResources().getInteger(R.integer.dim_hand_width), getResources().getInteger(R.integer.dim_hand_height)));
    scroll.addView(HandLayout);


    for (int i = 0; i < 8; i++){
        Button b = new Button(this);
        b.setWidth(200);
        HandLayout.addView(b);
     }

This shows the ScrollView with all 8 buttons and it is scrollable.
However, when I replace the last few lines with: 

    for (int i = 0; i < 8; i++){
        HeroCard hc = new HeroCard(this);
        HandLayout.addView(hc);
    }

Then nothing shows. HeroCard is a custom view that just implements the onDraw and the onCreate(Context context) methods (I won't copy the code as it's just that).

My guess is that Button is implementing a function that I'm not and that is why it is not drawing.

Any idea?

Thank you very much!

Use this:

hc.setWidth(200);
hc.setHeight(50);

In: 

for (int i = 0; i < 8; i++){
HeroCard hc = new HeroCard(this);
HandLayout.addView(hc);
}

And check the output.

Seems like you are not setting any params to your HeroCard view, it has no size, try to recover the params with getLayoutParams() and modify the width
