Passage of parameter Drawable object

Question

I created a method to encapsulate a notification message (Notification.Builder). An excerpt from the code is shown below:

 public void exibirMensagem(String titulo, String texto,Drawable icone)
{
    Notification.Builder mensagem = new Notification.Builder(contexto)
             //TROCAR PARA O ÍCONE PADRÃO DA APLICACAO
            .setSmallIcon(icone);}

It turns out that the method .setSmallIcone does not accept the icon object that was passed by parameter. icone is underlined in vermellho and when I step the mouse course appears the following message:

Cannot resolved method 'setSmallIcon(android.graphics.drawable.Drawable

How can I solve this, ie pass a Drawable as parameter and use in the method setSmallIcon?

Answer 1

According to the documentation, the parameter that must be passed to setSmallICon is a Int instead of a Drawable.

So your code should be like this:

public void exibirMensagem(String titulo, String texto, int icone)
{
    Notification.Builder mensagem = new Notification.Builder(contexto)
         //TROCAR PARA O ÍCONE PADRÃO DA APLICACAO
        .setSmallIcon(icone);
}

How to use the above code?

// FloatingActionButton -> OnClickListener...
exibirMensagem("hello world", "Hello world is so nice, guys!", R.drawable.ic_hello_app);
