How to turn a system out to string?

Question

I want to display a message on the device screen.

The message is in System.out.println("Mensagem ");

how do I turn into a string and print on screen using a textView?

Answer 1

Apart from the option to put the message in a Textview, you can also use a "Toast"

Example

//Toast.makeText(<Context>, <Mensagem>, <Duração>).show();

Toast.makeText(this, "this is my Toast message!!! =)", Toast.LENGTH_SHORT).show();

Application context, if it is in an Activity you can use this, Fragment can use the getActivity().getApplicationContext()

Message is self explanatory, is the text you want to show

Duration is the time the message will be on the screen, there are two constants with fixed times you can use, if you want you can put the time in milliseconds

Toast.LENGTH_SHORT // Equivale a 2 segundos
Toast.LENGTH_LONG // Equivale a 3.5 segundos

See if this helps.

 String mensagem = "Mensagem";

 TextView texto = (TextView)findViewById(R.id.id_do_texto_no_layout);

 texto.setText(mensagem);

To "print" on the android screen, we use a textview in the.xml layout of activity. Vc is trying to put on the android screen a text written "Message", but in string format. The last line texto.setText(mensagem); is basically the same line System.out.println("Mensagem "); but to display on android.
