基于 Android Studio 的事件安排，设置闹钟提醒且带有打卡功能的代码

以下是基于 Android Studio 的事件安排，设置闹钟提醒且带有打卡功能的代码：

1. 创建一个新的 Android Studio 项目。

2. 在项目的布局文件中添加一个 TextView，一个 Button 和一个 TimePicker。

3. 在 MainActivity.java 文件中添加以下代码：

public class MainActivity extends AppCompatActivity {

    private TextView mTextView;
    private Button mButton;
    private TimePicker mTimePicker;
    private AlarmManager mAlarmManager;
    private PendingIntent mPendingIntent;

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

        mTextView = findViewById(R.id.text_view);
        mButton = findViewById(R.id.button);
        mTimePicker = findViewById(R.id.time_picker);

        mAlarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        Intent intent = new Intent(this, AlarmReceiver.class);
        mPendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int hour = mTimePicker.getHour();
                int minute = mTimePicker.getMinute();

                Calendar calendar = Calendar.getInstance();
                calendar.setTimeInMillis(System.currentTimeMillis());
                calendar.set(Calendar.HOUR_OF_DAY, hour);
                calendar.set(Calendar.MINUTE, minute);

                mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), mPendingIntent);

                Toast.makeText(MainActivity.this, "Alarm set for " + hour + ":" + minute, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

4. 创建一个 AlarmReceiver 类，用于接收闹钟提醒广播，并添加以下代码：

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm received", Toast.LENGTH_SHORT).show();

        //TODO: Add punch function here
    }
}

5. 在 AlarmReceiver 类中添加打卡功能的代码，例如：

SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("punched", true);
editor.apply();

6. 在 MainActivity.java 中添加读取打卡状态的代码，例如：

SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
boolean punched = sharedPreferences.getBoolean("punched", false);
if (punched) {
    mTextView.setText("You have punched");
} else {
    mTextView.setText("You have not punched");
}

7. 运行应用程序，并设置闹钟提醒。当闹钟响起时，应用程序将显示“Alarm received”，并且打卡状态将更新为“已打卡”。
