我正在尝试创建一个测验游戏，该游戏将在活动结束时显示用户的分数。我有50个问题，但每次用户播放时只会显示10个问题。我遇到了麻烦，因为无法保存用户的分数。
以下是我的 java 代码，假设Q1.java和Q2.java是我的 java 类。 Whoami.java是用户开始测验的代码，score.java是显示分数的位置。请帮帮我们！提前谢谢！
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_question1);
TextView q1 = (TextView) findViewById(R.id.q1);
q1.setText("I am an amphibian who has undergone metamorphosis. I have slippery skin, and spend most of my time in or near water. I breathe with lungs now, but when I was a tadpole I had gills.");
}
@Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
int cnt = 0;
final Animation animScale = AnimationUtils.loadAnimation(this, R.animator.anim_scale);
final Animation animAlpha = AnimationUtils.loadAnimation(this, R.animator.anim_alphas);
Button btn1 = (Button) findViewById(R.id.btnopt1_a);
Button btn2 = (Button) findViewById(R.id.btnopt1_b);
Button btn3 = (Button) findViewById(R.id.btnopt1_c);
ImageView img1 = (ImageView) findViewById(R.id.imageView1);
ImageView img2 = (ImageView) findViewById(R.id.imageView2);
ImageView img3 = (ImageView) findViewById(R.id.imageView3);
img1.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animScale);
}});
img2.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animAlpha);
}});
img3.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animAlpha);
}});
if(btn1.isClickable())
{
img1.startAnimation(animScale);
cnt++;
Intent i = new Intent(this,Q2.class);
i.putExtra("score",cnt);
startActivity(i);
}
else if (btn2.isClickable())
{
img2.startAnimation(animAlpha);
}
else if (btn3.isClickable())
{
img3.startAnimation(animAlpha);
}
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
那么这是我的另一个名字Q2.java
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_question2);
TextView q2 = (TextView) findViewById(R.id.q2);
q2.setText("I am a bird that has wings, but does not fly. I spend most of my time in the water. I am known to live in colder regions like Antarctica.");
}
@Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
int cnt = 0;
final Animation animScale = AnimationUtils.loadAnimation(this, R.animator.anim_scale);
final Animation animAlpha = AnimationUtils.loadAnimation(this, R.animator.anim_alphas);
Button btn1 = (Button) findViewById(R.id.btnopt2_a);
Button btn2 = (Button) findViewById(R.id.btnopt2_b);
Button btn3 = (Button) findViewById(R.id.btnopt2_c);
ImageView img1 = (ImageView) findViewById(R.id.imageView1);
ImageView img2 = (ImageView) findViewById(R.id.imageView2);
ImageView img3 = (ImageView) findViewById(R.id.imageView3);
img1.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animScale);
}});
img2.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animAlpha);
}});
img3.setOnClickListener(new ImageView.OnClickListener()
{
@Override
public void onClick(View arg0) {
arg0.startAnimation(animAlpha);
}});
if(btn1.isClickable())
{
img1.startAnimation(animScale);
cnt++;
Intent i = new Intent(this,Q3.class);
i.putExtra("score",cnt);
startActivity(i);
}
else if (btn2.isClickable())
{
img2.startAnimation(animAlpha);
}
else if (btn3.isClickable())
{
img3.startAnimation(animAlpha);
}
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
这是我的Score.java
@Override
public void onCreate(Bundle savedInstanceState)
{
try
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_score);
Intent intent = getIntent();
int score = intent.getIntExtra("score",0);
Button btnok = (Button)findViewById(R.id.btnok);
btnok.setOnClickListener(this);
TextView txtscore = (TextView) findViewById(R.id.txtscore);
txtscore.setText("Your score is : " + score +"/10");
}
catch(Exception e)
{
try {
throw e;
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch (arg0.getId())
{
case R.id.btnok:
Intent i = new Intent (this,MainMenu.class);
startActivity(i);
default:
break;
}
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
最后是我的Whoami.java类
public class Whoami extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_whoami);
Button bplay =(Button) findViewById(R.id.bplay);
bplay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Random random = new Random();
switch(random.nextInt(50))

答案 0 :(得分：0)
创建一个QuestionActivity类和xml布局。 通过
将问题作为字符串传递给活动intentInstance.putExtra("question", yourRandomQuestion);
使用
从QuestionActivity类中获取传递的值Intent intent = getIntent();
String question = intent.getStringExtra("question");
然后将问题放入TextView。
希望它有所帮助：）
