Android 服务通知 onclick

Question

我有一个前台服务，我想让通知在用户点击通知时打开 MainActivity。

自定义Service类中创建Notification的方法是：

public void setForeground(final int notificationID, final int notificationIconID,
        final String notificationTickerText,
        final String notificationTitle, final String notificationText){
    Notification notification = new Notification(notificationIconID, notificationTickerText,
            System.currentTimeMillis());
    notification.setLatestEventInfo(this, notificationTitle,
            notificationText, PendingIntent.getActivity(this, 0, new Intent(this, this.getClass()), 0));
    startForeground(notificationID, notification);
}

如何修改它以包含打开（如果 MainActivity 当前已打开）或在通知点击功能上启动 MainActivity？

如果你想通过点击notification打开任意Activity，那么你需要实现TaskStackBuilder

Intent resultIntent = new Intent(this, ResultActivity.class);

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(ResultActivity.class);

// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent( 0,
                                    PendingIntent.FLAG_UPDATE_CURRENT);

mBuilder.setContentIntent(resultPendingIntent);
