Android Studio 计分牌代码进阶版可跳转

好的，以下是进阶版的代码，可以实现计分牌的功能，并且可以跳转到另一个 Activity：

MainActivity.java

public class MainActivity extends AppCompatActivity {
    private int scoreTeamA = 0;
    private int scoreTeamB = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btnAddOneTeamA = findViewById(R.id.btnAddOneTeamA);
        Button btnAddTwoTeamA = findViewById(R.id.btnAddTwoTeamA);
        Button btnAddThreeTeamA = findViewById(R.id.btnAddThreeTeamA);
        Button btnAddOneTeamB = findViewById(R.id.btnAddOneTeamB);
        Button btnAddTwoTeamB = findViewById(R.id.btnAddTwoTeamB);
        Button btnAddThreeTeamB = findViewById(R.id.btnAddThreeTeamB);
        Button btnReset = findViewById(R.id.btnReset);
        Button btnNext = findViewById(R.id.btnNext);

        btnAddOneTeamA.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamA = scoreTeamA + 1;
                displayForTeamA(scoreTeamA);
            }
        });

        btnAddTwoTeamA.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamA = scoreTeamA + 2;
                displayForTeamA(scoreTeamA);
            }
        });

        btnAddThreeTeamA.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamA = scoreTeamA + 3;
                displayForTeamA(scoreTeamA);
            }
        });

        btnAddOneTeamB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamB = scoreTeamB + 1;
                displayForTeamB(scoreTeamB);
            }
        });

        btnAddTwoTeamB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamB = scoreTeamB + 2;
                displayForTeamB(scoreTeamB);
            }
        });

        btnAddThreeTeamB.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamB = scoreTeamB + 3;
                displayForTeamB(scoreTeamB);
            }
        });

        btnReset.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                scoreTeamA = 0;
                scoreTeamB = 0;
                displayForTeamA(scoreTeamA);
                displayForTeamB(scoreTeamB);
            }
        });

        btnNext.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, NextActivity.class);
                intent.putExtra("scoreTeamA", scoreTeamA);
                intent.putExtra("scoreTeamB", scoreTeamB);
                startActivity(intent);
            }
        });
    }

    private void displayForTeamA(int score) {
        TextView scoreView = findViewById(R.id.scoreTeamA);
        scoreView.setText(String.valueOf(score));
    }

    private void displayForTeamB(int score) {
        TextView scoreView = findViewById(R.id.scoreTeamB);
        scoreView.setText(String.valueOf(score));
    }
}

NextActivity.java

public class NextActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_next);

        TextView scoreViewTeamA = findViewById(R.id.scoreTeamANext);
        TextView scoreViewTeamB = findViewById(R.id.scoreTeamBNext);
        Intent intent = getIntent();
        int scoreTeamA = intent.getIntExtra("scoreTeamA", 0);
        int scoreTeamB = intent.getIntExtra("scoreTeamB", 0);
        scoreViewTeamA.setText(String.valueOf(scoreTeamA));
        scoreViewTeamB.setText(String.valueOf(scoreTeamB));
    }
}

在这个版本中，我们新增了一个名为 `NextActivity` 的 Activity，并在 `MainActivity` 中添加了一个名为 `btnNext` 的按钮，点击该按钮可以跳转到 `NextActivity` 中。同时，我们在 `MainActivity` 中将当前的分数传递给了 `NextActivity`，在 `NextActivity` 中将接收到的分数显示出来。

请注意，为了让跳转功能正常运行，你需要在 AndroidManifest.xml 中添加以下代码：

<activity android:name=".NextActivity"></activity>

这样就完成了进阶版的计分牌代码，并且可以跳转到另一个 Activity 中。
