开发中有时需要实现各种样式的通知栏通知功能，比如
1、浮动通知
/**
* 浮动通知 在[5.0,8.0)的系统中浮动通知的产生条件
* 是NotificationCompat.Builder中设置setPriority()的参数
* 必须在NotificationCompat.PRIORITY_HIGH及以上并且有铃声或者震动才能有效果
* 但在[8.0，8.0+)的时候因为NotificationChannel中的设置高于一切 所以
* NotificationChannel中的importance必须要在NotificationManager.IMPORTANCE_HIGH及以上(!注意 此时会有默认的铃声和震动的效果哦～)
* 5.0以下的系统就不支持啦
*
* @param noticationId
* @param pendingIntent
* @param largeIcon
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param sound
* @param vibrate
* @param light
*/
public void notifyHeadUp(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, boolean sound, boolean vibrate, boolean light) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
if (notificationChannel.getImportance() < NotificationManager.IMPORTANCE_HIGH) {
notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(notificationChannel);
}
}
// else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
//
//
// }
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, NotificationCompat.PRIORITY_HIGH, sound, vibrate, light);
notifyNotification(noticationId);
}2、带进度条通知
/**
* 在5.0的系统以下没有进度条显示 8.0及以上显示进度条是没有铃声和震动的效果的
*
* @param noticationId
* @param pendingIntent
* @param largeIcon
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param maxProgress
* @param curProgress
*/
public void notifyProgress(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int maxProgress, int curProgress) {
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, NotificationCompat.PRIORITY_HIGH, false, true, false);
if (curProgress >= maxProgress) {
builder.setProgress(0, 0, false);
} else {
builder.setProgress(maxProgress, curProgress, false);
}
notifyNotification(noticationId);
}3、消息类通知
/**
* 发送一个消息类的通知7.0以上有效 7.0以下效果不友好
*
* @param noticationId
* @param pendingIntent
* @param largeIcon
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param priority
* @param sound
* @param vibrate
* @param light
*/
public void notifyMessageType(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int priority, boolean sound, boolean vibrate, boolean light) {
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, priority, sound, vibrate, light);
builder.setStyle(new NotificationCompat.MessagingStyle(contentTitle).setConversationTitle("xx")
.addMessage(new NotificationCompat.MessagingStyle.Message(contentText, System.currentTimeMillis(), "wo")));
notifyNotification(noticationId);
}4、带按钮通知
/**
* 添加两个左右的按钮 发送通知
* <p>
* 按钮最多可以加到三个
*
* @param noticationId
* @param pendingIntent
* @param leftPendingIntent
* @param leftIcon
* @param leftBtnText
* @param rightPendingIntent
* @param rightIcon
* @param rightBtnText
* @param largeIcon
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param priority
* @param sound
* @param vibrate
* @param light
*/
public void notifyButton(int noticationId, PendingIntent pendingIntent, PendingIntent leftPendingIntent, int leftIcon, CharSequence leftBtnText, PendingIntent rightPendingIntent, int rightIcon, CharSequence rightBtnText, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int priority, boolean sound, boolean vibrate, boolean light) {
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, priority, sound, vibrate, light);
builder.addAction(leftIcon, leftBtnText, leftPendingIntent);
builder.addAction(rightIcon, rightBtnText, rightPendingIntent);
notifyNotification(noticationId);
}5、带大图通知
/**
* 大图的通知类型
*
* @param noticationId
* @param pendingIntent
* @param largeIcon
* @param bigPicFilePath 大图的绝对路径地址
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param priority
* @param sound
* @param vibrate
* @param light
*/
public void notifyBigPic(Context context, int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, String bigPicFilePath, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int priority, boolean sound, boolean vibrate, boolean light) {
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, priority, sound, vibrate, light);
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
options.inScaled = true;
// Calculate inSampleSize
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
//避免出现内存溢出的情况，进行相应的属性设置。
options.inPreferredConfig = Bitmap.Config.RGB_565;
options.inDither = true;
// Bitmap bitmap = BitmapFactory.decodeFile(bigPicFilePath, options);
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.mipmap.bg_man);
bigPictureStyle.bigLargeIcon(bitmap);
bigPictureStyle.bigPicture(bitmap);
// bigPictureStyle.setBigContentTitle("这是大图");
// bigPictureStyle.setSummaryText("这是大图的Summary");
builder.setStyle(bigPictureStyle);
notifyNotification(noticationId);
}6、文字类型折叠通知
/**
* 发送长文字类型的通知 5.0以下长文字会全部显示出来 5.0以上会折叠
*
* @param noticationId
* @param pendingIntent
* @param largeIcon
* @param smallIcon
* @param ticker
* @param subText
* @param contentTitle
* @param contentText
* @param priority
* @param sound
* @param vibrate
* @param light
*/
public void notifyBigText(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int priority, boolean sound, boolean vibrate, boolean light) {
builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, priority, sound, vibrate, light);
// if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle();
bigTextStyle.bigText(contentText);
builder.setStyle(bigTextStyle);
// }
notifyNotification(noticationId);
}7、普通通知
8、自定义view的通知
因为可以自定义，所以该工具类基本满足了所有的通知栏样式需求。
使用也非常简单，只需要调用不同方法即可。
