android studio 分数，当前高分和总高分

Question

我正在开发一款游戏，并且我具有中级代码知识。我的游戏一共有 10 个关卡。我立即记录分数并与该级别的高分进行比较，这更多。

我想保留每个级别的高分数据，并将其与所有级别一起收集并打印 TextView。

您将在我尝试使用 Sharedpreferences 的代码中看到。结果：每个级别都将自己的高分写入 TextView。我希望将所有级别的高分总和写入 TextView。

public class Main2Activity extends AppCompatActivity {
    TextView scoreText,failedText,successText,highScoreText,randomArray;
    int score;
    public static int highScore,totalScore,totalScore2;

    @SuppressLint("MissingInflatedId")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        score = 0;

        //totalScore = highScore + totalScore2;
        //totalScore2 = key.getInt("high_score_level2",0);

        //Toast.makeText(this, "Genel Skor : "+ totalScore , Toast.LENGTH_LONG).show();
        Toast.makeText(this, "High : "+ highScore , Toast.LENGTH_LONG).show();

        levelFailed = getResources().getStringArray(R.array.levelFailed);
        levelSuccess = getResources().getStringArray(R.array.levelSuccess);
        highScoreText = (TextView) findViewById(R.id.txtHighScore);
        startTimer();
}

        private void startTimer(){
        start = new CountDownTimer(10000, 1000) {

            @Override
            public void onTick(long millisUntilFinished) {
                timeText = (TextView) findViewById(R.id.textTime);
                timeText.setText("Zaman : " + millisUntilFinished / 1000);
            }

            @Override
            public void onFinish() {
                timeText = (TextView) findViewById(R.id.textTime);
                timeText.setText("Süre Doldu ! ");
                handler.removeCallbacks(runnable);

                for (ImageView image : imageArray) {
                    image.setVisibility(View.INVISIBLE);
                }
                int x = 0;
                if (score < 10){
                    showFailedAlertDialog(R.layout.my_failed_dialog);

                }
                else if (score >= 10){
                    showAlertDialog(R.layout.my_success_dialog);
                    highScore();
                }


            }
        }.start();
    }


@SuppressLint("SetTextI18n")
    public void highScore(){
        SharedPreferences myScore = getSharedPreferences("my_pref",MODE_PRIVATE);

        if (highScore > score) {
            highScoreText.setText("Highscore: " + highScore);

        } else {
            highScore = score;
            highScoreText.setText("Highscore: " + highScore);
            myScore.edit().putInt("high_score_level1", highScore).apply();

            user = FirebaseAuth.getInstance().getCurrentUser();
            //Upload user data
            if (isOnline() && user != null && user.getDisplayName() != null) {
                final DatabaseReference refDirect = FirebaseDatabase.getInstance().getReference();
                refDirect.addListenerForSingleValueEvent(new ValueEventListener() {
                    @Override
                    public void onDataChange(DataSnapshot dataSnapshot) {
                        refDirect.child("Users" + "/" + user.getUid() +   
                        "/name").setValue(user.getDisplayName());
                        refDirect.child("Users" + "/" + user.getUid() + 
                        "/image").setValue(user.getPhotoUrl().toString());
                        refDirect.child("Users" + "/" + user.getUid() + "/highscore").setValue(highScore);


                    }

                    @Override
                    public void onCancelled(DatabaseError databaseError) {
                    }

                });
            }
        }
    }



        public void showAlertDialog(int my_success_dialog){
        builderDialog = new AlertDialog.Builder(this);
        View layoutView = getLayoutInflater().inflate(R.layout.my_success_dialog,null);

        if (mInterstitialAd != null) {
            mInterstitialAd.show(Main2Activity.this);
        } else {
            Log.d("TAG", "The interstitial ad wasn't ready yet.");
        }

        randomArray = (TextView) layoutView .findViewById(R.id.successMessage);
        randomArray.setText("");

        successText = (TextView) layoutView .findViewById(R.id.txtSuccessScore);
        successText.setText("Skor: " + score);

        highScoreText = (TextView) layoutView .findViewById(R.id.txtHighScore);
        highScoreText.setText("Highscore: " + highScore);

        int randomIndex = new Random().nextInt(levelSuccess.length);
        String randomName = levelSuccess[randomIndex];
        randomArray.setText(randomName);

        AppCompatButton dialogButton = layoutView.findViewById(R.id.successAnaMenu);
        AppCompatButton dialogButtonTwo = layoutView.findViewById(R.id.successNextLevel);
        builderDialog.setView(layoutView);
        builderDialog.setCancelable(false);
        alertDialog = builderDialog.create();
        alertDialog.show();

        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                Main2Activity.this.startActivity(intent);
            }
        });

        dialogButtonTwo.setOnClickListener(new View.OnClickListener() {

                Main2Activity.this.startActivity(intent);

}

更新：

SharedPreferences myScore = getSharedPreferences("my_pref",MODE_PRIVATE);
        totalScore = myScore.getInt("high_score_level2",0);
        Toast.makeText(this, "Highscore level2 : "+ totalScore , Toast.LENGTH_LONG).show();
        if (highScore > score) {
            highScoreText.setText("Highscore: " + highScore + totalScore);

        } else {
            highScore = score;
            highScoreText.setText("Highscore: " + highScore + totalscore);
            myScore.edit().putInt("high_score_level1", highScore).apply();

由于数据结构尚未详细说明或检索，因此我提供了一个假设任意键名称的随机示例。请根据您的要求更换。

每当更新分数时，您都需要使用 for 循环计算最高分数。此外，我正在存储高分以供其他用途

final DatabaseReference refDirect = FirebaseDatabase.getInstance().getReference();
refDirect.addListenerForSingleValueEvent(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        String uid = user.getUid();
        refDirect.child("Users").child(uid).child("name").setValue(user.getDisplayName());
        refDirect.child("Users").child(uid).child("image").setValue(user.getPhotoUrl().toString());

        // Assuming you have a list of levels and their respective high scores
        List<LevelScore> levelScores = calculateHighScoresForLevels(dataSnapshot);

        int totalHighScore = 0;

        for (LevelScore levelScore : levelScores) {
            refDirect.child("Users").child(uid).child("highscores")
                .child(levelScore.getLevelId()).setValue(levelScore.getScore());

            totalHighScore += levelScore.getScore(); // Calculate total high score
        }

        refDirect.child("Users").child(uid).child("totalHighScore").setValue(totalHighScore);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {
        // Handle onCancelled if needed
    }
});
