从图层列表中动态删除图层

Question

I would like to remove/hide a layer in a layer-list during runtime. How do I do this?

I built a solution that works, but it feels a bit hackish.

I replace the desired layer with a transparent image:

LayerDrawable layerDrawable = (LayerDrawable) res.getDrawable(R.drawable.ic_layer);
Drawable digit = res.getDrawable(R.drawable.ic_number_empty);
layerDrawable.setDrawableByLayerId(R.id.layer_digit, digit);

Is there a better way to do this?

Answer 1

layerDrawable.findDrawableByLayerId(R.id.layer_digit).setAlpha(0)怎么样？
