Android 久坐提醒：使用 NotificationCompat.Builder 设置振动提醒

长时间坐着对健康有害，因此拥有一个提醒我们定期起身活动的应用程序非常有用。本文将指导您使用 Android 的 NotificationCompat.Builder 类创建一个简单的久坐提醒应用程序，该应用程序会发出带有自定义振动模式的通知。

代码示例

以下是完整的代码：javaimport android.app.Activity;import android.app.NotificationChannel;import android.app.NotificationManager;import android.content.Context;import android.os.Build;import android.os.Bundle;import android.os.Handler;import android.view.View;import android.widget.Button;

import androidx.core.app.NotificationCompat;

public class jiuzuo extends Activity { private static final long REMINDER_INTERVAL = 60 * 60 * 1000; // 1小时 private static final int NOTIFICATION_ID = 1; private static final String CHANNEL_ID = 'sit_reminder_channel'; private Handler handler; private Runnable reminderRunnable;

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

    Button startButton = findViewById(R.id.start_button);        Button stopButton = findViewById(R.id.stop_button);

    handler = new Handler();        reminderRunnable = new Runnable() {            @Override            public void run() {                showReminder();                handler.postDelayed(this, REMINDER_INTERVAL);            }        };

    startButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                startReminder();            }        });

    stopButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                stopReminder();            }        });    }

private void startReminder() {        handler.postDelayed(reminderRunnable, REMINDER_INTERVAL);    }

private void stopReminder() {        handler.removeCallbacks(reminderRunnable);    }

private void showReminder() {        createNotificationChannel();

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)                .setSmallIcon(R.drawable.ic_notification)                .setContentTitle('久坐提醒')                .setContentText('您已长时间未活动，请起身活动一下。')                .setVibrate(new long[]{0, 1000, 1000, 1000, 1000})                .setAutoCancel(true);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);        notificationManager.notify(NOTIFICATION_ID, builder.build());    }

private void createNotificationChannel() {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {            CharSequence name = 'Sit Reminder';            String description = '久坐提醒通知';            int importance = NotificationManager.IMPORTANCE_DEFAULT;            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);            channel.setDescription(description);

        NotificationManager notificationManager = getSystemService(NotificationManager.class);            notificationManager.createNotificationChannel(channel);        }
