TextView tInforme;
EditText tValor;
Button btDescobrir;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_exercicio1);

    tInforme = (TextView) findViewById(R.id.tInforme);
    tValor = (EditText) findViewById(R.id.tValor);

        public void setbtDescobrir(View v) {
            String guessStr = tValor.getText().toString();
            int theGuess = Integer.parseInt(guessStr);

        }}

Answer 1

Use the the operation % it returns you the rest of a division. In case divided by 2 %2and if the result is 0 it means that it is even, if it is not odd

String guessStr = tValor.getText().toString();
   int theGuess = Integer.parseInt(guessStr);
   int valor = theGuess%2;
   if(valor == 0){
      //imprima é par
   }
   else if(valor == 1){
    // imprima é impar
   }
