I need help on SetBackgroundResource, how do I apply this to a button that is in MainActivity (main_bt_padra) but I want the result in a TextView (ct_tv_gl_topo) that is in another Activity.
main_bt_padrao.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View view) {
ct_tv_gl_topo.setBackgroundResource( R.drawable.cotacao_azul_ganho_liquido_topo );
You are in MainActivity
main_bt_padrao
You are on CotacaoActivty
ct_tv_gl_topo
