【问题描述】：
我正在制作一个类似于徽标测验的游戏。我有问题活动和关卡活动，所以当用户正确回答时，他们得分 1。然后我想把分数放在关卡活动中，这样用户就可以解锁下一个关卡，但我不希望用户离开问题活动，直到现在我才找到这种方法：
Intent resultIntent = new Intent(this, NextActivity.class);
resultIntent.putExtra("score", score);
startActivity(resultIntent);
但是，使用此方法，用户会转到关卡活动。
我将留下我的代码以供参考：
public class Big extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_big);
init();
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true); }
public boolean onOptionsItemSelected(MenuItem item){
Intent myIntent = new Intent(getApplicationContext(), Level1.class);
startActivityForResult(myIntent, 0);
return true;
}
private Button buttonSaveMem1;
private EditText escrive;
private TextView respuest;
private String [] answers;
int score=0;
int HighScore;
private String saveScore = "HighScore";
private int currentQuestion;
public void init()
{
answers = new String[]{"Big"};
buttonSaveMem1 = (Button)findViewById(R.id.button1);
respuest = (TextView) findViewById(R.id.textView2);
escrive = (EditText) findViewById(R.id.editText1);
buttonSaveMem1.setOnClickListener(buttonSaveMem1OnClickListener);
LoadPreferences();
}
Button.OnClickListener buttonSaveMem1OnClickListener
= new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
checkAnswer();
// TODO Auto-generated method stub
SavePreferences();
LoadPreferences();
}};
public boolean isCorrect(String answer)
{
return (answer.equalsIgnoreCase(answers[currentQuestion]));
}
public void checkAnswer() {
String answer = escrive.getText().toString();
if(isCorrect(answer)) {
update();
respuest.setText("You're right!" + " The Answer is " + answer + " your score is:" + score +" " +
"HighScore: " + HighScore);
score =1;
}
else {
respuest.setText("Sorry, The answer is not right!");
}
}
private void update() {
if (score > HighScore)
{ HighScore = score; }
}
private void SavePreferences(){
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("MEM1", respuest.getText().toString());
sharedPreferences.edit().putInt(saveScore, HighScore).commit();
editor.commit();
}
private void LoadPreferences(){
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
String strSavedMem1 = sharedPreferences.getString("MEM1", "");
HighScore = sharedPreferences.getInt(saveScore, 0);
respuest.setText(strSavedMem1);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是关卡活动：
public class Level extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level);
Button salir = (Button) findViewById(R.id.button3);
salir.setOnClickListener( new View.OnClickListener() {
@Override public void onClick(View v) {
startActivity(new Intent(Level.this, MainActivity.class)); }
}
)
;
Button leve2 = (Button) findViewById(R.id.button1);
leve2.setOnClickListener( new View.OnClickListener() {
@Override public void onClick(View v) {
startActivity(new Intent(Level.this, Level2.class)); }
}
)
; }
Button leve1 = (Button) findViewById(R.id.button1);
leve1.setOnClickListener( new View.OnClickListener() {
@Override public void onClick(View v) {
startActivity(new Intent(Level.this, Level1.class)); }
}
)
;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.level, menu);
return true;
}
}
感谢您的帮助！
【问题讨论】：
-
看起来您已经在使用 SharedPreferences 来保存用户的高分，为什么不使用它们来存储在问题上获得的分数，然后在用户返回级别活动时获取该分数?

耶稣...请格式化您的代码。
