要实现Android定时通知带有按钮,可以使用PendingIntent和NotificationCompat类。以下是一个代码示例:
import android.app.AlarmManager;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import androidx.core.app.NotificationCompat;
import androidx.core.app.RemoteInput;
import java.util.Calendar;
public class NotificationUtils {
private static final String CHANNEL_ID = "channel_id";
private static final String CHANNEL_NAME = "channel_name";
private static final int NOTIFICATION_ID = 1;
private static final String KEY_REPLY = "key_reply";
public static void scheduleNotification(Context context, int hour, int minute) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.SECOND, 0);
Intent notificationIntent = new Intent(context, NotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
public static void createNotificationChannel(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
NotificationManager notificationManager = context.getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
public static void showNotification(Context context) {
createNotificationChannel(context);
RemoteInput remoteInput = new RemoteInput.Builder(KEY_REPLY)
.setLabel("Reply")
.build();
Intent replyIntent = new Intent(context, ReplyReceiver.class);
PendingIntent replyPendingIntent = PendingIntent.getBroadcast(context, 0, replyIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Action replyAction = new NotificationCompat.Action.Builder(android.R.drawable.ic_menu_send, "Reply", replyPendingIntent)
.addRemoteInput(remoteInput)
.build();
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(android.R.drawable.ic_dialog_info)
.setContentTitle("Notification Title")
.setContentText("Notification Message")
.addAction(replyAction);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, builder.build());
}
public static class NotificationReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
showNotification(context);
}
}
public static class ReplyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Bundle remoteInputBundle = RemoteInput.getResultsFromIntent(intent);
if (remoteInputBundle != null) {
CharSequence replyText = remoteInputBundle.getCharSequence(KEY_REPLY);
// 处理用户回复的文本
}
}
}
}
使用示例:
// 在Activity或Fragment中调用以下方法来设置定时通知
NotificationUtils.scheduleNotification(this, 8, 0); // 设置通知在每天的8:00 AM发送
// 在AndroidManifest.xml文件中注册NotificationReceiver和ReplyReceiver
上述代码中,NotificationUtils
类包含了以下几个方法:
scheduleNotification(Context context, int hour, int minute)
:设置定时通知,指定通知发送的时间(小时和分钟)。createNotificationChannel(Context context)
:创建通知渠道,仅在Android 8.0及以上版本需要调用。showNotification(Context context)
:显示通知,其中包含了一个带有按钮的通知。NotificationReceiver
:接收定时通知的广播接收器,当定时时间到达时,会发送通知。ReplyReceiver
:接收用户回复的广播接收器,当用户点击通知中的回复按钮时,会接收到用户的回复文本。要使用上述代码,需要在AndroidManifest.xml文件中注册NotificationReceiver
和ReplyReceiver
。
