我想在问答游戏结束时显示分数。我在两个班上做到了。我的分数代码是:
public class Helper {
/**
* This method selects a end game response based on the players score
* @param numCorrect - number of correct answers
* @param numRounds - number of rounds
*/
public static int getResult(int numCorrect, int numRounds){
//calculate percentage
int hasil = calculatePercentage(numCorrect, numRounds);
return hasil;
}
/**
* Calculate the percentage result based on the number correct and number of questions
*
* @param numCorrect - number of questions right
* @param numRounds - total number of questions
* @return int percentage correct
*/
private static int calculatePercentage(int numCorrect, int numRounds) {
double result = (double)numCorrect/(double)numRounds;
int percentage = (int) result*100;
return percentage;
}
}
和
public class ResultPretest1 extends Activity implements OnClickListener{
TextView txtNilai;
Button tutorial;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_result_pretest1);
GamePlay currentGame = ((BenkyouApplication)getApplication()).getCurrentGame();
int nilai = Helper.getResult(currentGame.getRight(), currentGame.getNumRounds());
txtNilai = (TextView)findViewById(R.id.nilai);
txtNilai.setText(String.valueOf(nilai));
tutorial = (Button) findViewById(R.id.tutorial);
tutorial.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.result, menu);
return true;
}
/*private static int calculatePercentage(final int numCorrect, final int numRounds) {
int score = 0;
score = numCorrect/numRounds*100;
return score;
}*/
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.tutorial :
tutorial.setBackgroundResource(R.drawable.tutorial1);
Intent tulv1 = new Intent(this, TutorialLevel1.class);
startActivity(tulv1);
break;
}
}
/* (non-Javadoc)
* @see android.app.Activity#onKeyDown(int, android.view.KeyEvent)
*
* This method is to override the back button on the phone
* to prevent users from navigating back in to the quiz
*/
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
switch (keyCode)
{
case KeyEvent.KEYCODE_BACK :
return true;
}
return super.onKeyDown(keyCode, event);
}
}
如果您设法正确回答所有问题,则得分为 100,但如果有错误的答案,分数始终显示为 0。如果答案错误,分数不会降低,并且始终为 0。为什么?请帮忙....
