整理的Android多种控件步骤

Notification步骤：

1、onCreate方法中mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

2、在点击事件事件监听中：

Notification notification=new Notification(R.drawable.earlybird, "小鸟飞啊飞", System.currentTimeMillis());

Intent intent=new Intent(MainActivity.this,SecondActivity.class);

PendingIntent contentIntent=PendingIntent.getActivity(MainActivity.this, 0, intent, 0);

notification.setLatestEventInfo(MainActivity.this, "愤怒的小鸡", "愤怒的小鸟与愤怒的小鸡", contentIntent);

notification.flags=Notification.FLAG_AUTO_CANCEL;//点击后自动消失

mNotificationManager.notify(1, notification);

Toast步骤：

1、Toast.makeText(MainActivity.this, "我是愤怒的小鸡", Toast.LENGTH_SHORT).show();

//切记记得.show()方法，让Toast显示出来

//Toast不会获取焦点，提示消息过了一段时间会自动消失,不需要用户去点击确认，也不需要用户去反馈

//在应用的其他界面依然能够看到Toast提示
