android篮球计分器两个界面两个代码

好的，下面是一个简单的 Android 篮球计分器应用程序的两个界面和代码实现：

1. 主界面

主界面包括两个篮球场地图，每个地图都有一个计分板和一个时间计时器。每个计分板应该显示两个队伍的分数、个人犯规和队伍犯规。时间计时器应该有开始、停止和重置按钮。此外，还应该有一个撤销按钮，以撤销上一次得分或犯规操作。

主界面的代码实现如下：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private TextView tvTeam1Name, tvTeam2Name, tvTeam1Score, tvTeam2Score, tvTeam1PersonalFoul, tvTeam2PersonalFoul, tvTeam1TeamFoul, tvTeam2TeamFoul, tvTime;
    private Button btnStart, btnStop, btnReset, btnUndo;
    private ImageView ivCourt1, ivCourt2;

    private int team1Score = 0, team2Score = 0;
    private int team1PersonalFoul = 0, team2PersonalFoul = 0;
    private int team1TeamFoul = 0, team2TeamFoul = 0;
    private boolean isTimerStarted = false;
    private boolean isTimerPaused = false;
    private CountDownTimer countDownTimer;
    private long timeLeftInMillis = 0;

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

        tvTeam1Name = findViewById(R.id.tv_team1_name);
        tvTeam2Name = findViewById(R.id.tv_team2_name);
        tvTeam1Score = findViewById(R.id.tv_team1_score);
        tvTeam2Score = findViewById(R.id.tv_team2_score);
        tvTeam1PersonalFoul = findViewById(R.id.tv_team1_personal_foul);
        tvTeam2PersonalFoul = findViewById(R.id.tv_team2_personal_foul);
        tvTeam1TeamFoul = findViewById(R.id.tv_team1_team_foul);
        tvTeam2TeamFoul = findViewById(R.id.tv_team2_team_foul);
        tvTime = findViewById(R.id.tv_time);
        btnStart = findViewById(R.id.btn_start);
        btnStop = findViewById(R.id.btn_stop);
        btnReset = findViewById(R.id.btn_reset);
        btnUndo = findViewById(R.id.btn_undo);
        ivCourt1 = findViewById(R.id.iv_court1);
        ivCourt2 = findViewById(R.id.iv_court2);

        btnStart.setOnClickListener(this);
        btnStop.setOnClickListener(this);
        btnReset.setOnClickListener(this);
        btnUndo.setOnClickListener(this);

        // 初始化计时器
        timeLeftInMillis = 60000;
        updateCountDownText();

        // 初始化撤销按钮状态
        btnUndo.setEnabled(false);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_start:
                startTimer();
                break;
            case R.id.btn_stop:
                pauseTimer();
                break;
            case R.id.btn_reset:
                resetTimer();
                break;
            case R.id.btn_undo:
                undoLastAction();
                break;
        }
    }

    // 开始计时器
    private void startTimer() {
        if (!isTimerStarted) {
            countDownTimer = new CountDownTimer(timeLeftInMillis, 1000) {
                @Override
                public void onTick(long millisUntilFinished) {
                    timeLeftInMillis = millisUntilFinished;
                    updateCountDownText();
                }

                @Override
                public void onFinish() {
                    isTimerStarted = false;
                    isTimerPaused = false;
                    btnStart.setEnabled(true);
                    btnStop.setEnabled(false);
                    btnReset.setEnabled(true);
                    btnUndo.setEnabled(false);
                    timeLeftInMillis = 0;
                    updateCountDownText();
                    Toast.makeText(MainActivity.this, "比赛结束！", Toast.LENGTH_SHORT).show();
                }
            }.start();

            isTimerStarted = true;
            isTimerPaused = false;
            btnStart.setEnabled(false);
            btnStop.setEnabled(true);
            btnReset.setEnabled(false);
            btnUndo.setEnabled(true);
        } else if (isTimerPaused) {
            countDownTimer.resume();
            isTimerPaused = false;
            btnStart.setEnabled(false);
            btnStop.setEnabled(true);
            btnReset.setEnabled(false);
            btnUndo.setEnabled(true);
        }
    }

    // 暂停计时器
    private void pauseTimer() {
        if (isTimerStarted && !isTimerPaused) {
            countDownTimer.pause();
            isTimerPaused = true;
            btnStart.setEnabled(true);
            btnStop.setEnabled(false);
            btnReset.setEnabled(true);
            btnUndo.setEnabled(true);
        }
    }

    // 重置计时器
    private void resetTimer() {
        if (isTimerStarted || isTimerPaused) {
            countDownTimer.cancel();
            isTimerStarted = false;
            isTimerPaused = false;
            btnStart.setEnabled(true);
            btnStop.setEnabled(false);
            btnReset.setEnabled(false);
            btnUndo.setEnabled(false);
            timeLeftInMillis = 60000;
            updateCountDownText();
        }
    }

    // 撤销上一次得分或犯规操作
    private void undoLastAction() {
        // TODO: 撤销上一次得分或犯规操作的代码
    }

    // 更新倒计时文本
    private void updateCountDownText() {
        int minutes = (int) (timeLeftInMillis / 1000) / 60;
        int seconds = (int) (timeLeftInMillis / 1000) % 60;
        String timeLeftFormatted = String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds);
        tvTime.setText(timeLeftFormatted);
    }
}

2. 设置界面

设置界面包括设置球队名称、队长、颜色和背景图像等选项。此外，还应该有一个计时器设置选项，允许用户设置每个节次的持续时间和休息时间。

设置界面的代码实现如下：

public class SettingsActivity extends AppCompatActivity implements View.OnClickListener {

    private EditText etTeam1Name, etTeam2Name, etTeam1Captain, etTeam2Captain, etTeam1Color, etTeam2Color;
    private ImageView ivTeam1Background, ivTeam2Background;
    private Button btnSave;

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

        etTeam1Name = findViewById(R.id.et_team1_name);
        etTeam2Name = findViewById(R.id.et_team2_name);
        etTeam1Captain = findViewById(R.id.et_team1_captain);
        etTeam2Captain = findViewById(R.id.et_team2_captain);
        etTeam1Color = findViewById(R.id.et_team1_color);
        etTeam2Color = findViewById(R.id.et_team2_color);
        ivTeam1Background = findViewById(R.id.iv_team1_background);
        ivTeam2Background = findViewById(R.id.iv_team2_background);
        btnSave = findViewById(R.id.btn_save);

        btnSave.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_save:
                saveSettings();
                break;
        }
    }

    // 保存设置
    private void saveSettings() {
        String team1Name = etTeam1Name.getText().toString();
        String team2Name = etTeam2Name.getText().toString();
        String team1Captain = etTeam1Captain.getText().toString();
        String team2Captain = etTeam2Captain.getText().toString();
        String team1Color = etTeam1Color.getText().toString();
        String team2Color = etTeam2Color.getText().toString();

        // TODO: 保存设置的代码
    }
}

以上是一个简单的 Android 篮球计分器应用程序的两个界面和代码实现，你可以根据自己的需求进行更改和优化。
