目前在 Android Studio 中工作并遇到了一些麻烦。试图让我的 rollScore 按钮不断滚动。此时它“滚动”一次并停止。我尝试过 for 循环和 while 循环，但无法让它允许多个“滚动”。
public class GameScreen extends AppCompatActivity {
private Button rollButton; // Roll button being declared as a variable
private TextView rollScore; // Text view being declared as a variable
private TextView totalSCore; //
private int mCounter = 0;
private int totalRuns = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_screen);
Random randomGenerator = new Random();
final int randomInt = randomGenerator.nextInt(7) + 1;
rollButton = (Button) findViewById(R.id.rollButton);
rollScore = (TextView) findViewById(R.id.rollScore);
totalSCore = (TextView) findViewById(R.id.totalScore);
rollButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
rollScore.setText(Integer.toString(randomInt));
mCounter++;
}
});
}
}
最佳答案
每次点击按钮时，您都必须生成一个新的随机数。
像这样:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_screen);
Random randomGenerator = new Random();
int randomInt;
rollButton = (Button) findViewById(R.id.rollButton);
rollScore = (TextView) findViewById(R.id.rollScore);
totalSCore = (TextView) findViewById(R.id.totalScore);
rollButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
randomInt = randomGenerator.nextInt(7) + 1;
rollScore.setText(Integer.toString(randomInt));
mCounter++;
}
});
}
