java - 安卓猜数字游戏？如何在用户正确时更改随机数？

Question

我正在尝试更改应用程序启动时生成的随机数并要求用户提供新的输入？如您所见，当前代码显示，如果用户猜对了数字，他将不得不重新启动应用程序。我不想这样做，而是想在客户正确时继续更改随机数。

public class MainActivity extends Activity {

int randomNumber;
int number;

public void randomNumberGenerator (View view){
    EditText userInput = (EditText)findViewById(R.id.userRandomText);
    do {
        number = Integer.parseInt(userInput.getText().toString());

        if (number == randomNumber) {
            Toast.makeText(getApplicationContext(), "Your number " + number + "is equal to generated number. CONGRATULATION !! Try Again: ", Toast.LENGTH_SHORT).show();
        } else if (number < randomNumber) {
            Toast.makeText(getApplicationContext(), "Your number " + number + "is lower than generated random number", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(getApplicationContext(), "Your number " + number + "is greater than generated random number", Toast.LENGTH_SHORT).show();
        }
          };

  @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_activity_udemy);
    //Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    //setSupportActionBar(toolbar);

    Random randomGenerator = new Random();
    randomNumber = randomGenerator.nextInt(20);
    System.out.print(randomNumber);

Answer 1

将这些行移动到 generateRandomNumber

Random randomGenerator = new Random();
randomNumber = randomGenerator.nextInt(20);
System.out.print(randomNumber);

然后你可以在用户猜对的时候再次添加这个

randomNumber = randomGenerator.nextInt(20);

所以你的代码看起来像这样

Random randomGenerator = new Random();
randomNumber = randomGenerator.nextInt(20);
System.out.print(randomNumber);
do {
    number = Integer.parseInt(userInput.getText().toString());
    if (number == randomNumber) {
        Toast.makeText(getApplicationContext(), "Your number " + number + "is equal to generated number. CONGRATULATION !! Try Again: ", Toast.LENGTH_SHORT).show();
        randomNumber = randomGenerator.nextInt(20);
    } else if (number < randomNumber) {
        Toast.makeText(getApplicationContext(), "Your number " + number + "is lower than generated random number", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(getApplicationContext(), "Your number " + number + "is greater than generated random number", Toast.LENGTH_SHORT).show();
    }
}
