Android NotificationManager简单使用详解

本文实例为大家分享了Android NotificationManager的简单使用代码,供大家参考,具体内容如下

我们有时候需要使用通知,先要获得一个通知管理器,然后通过通知管理器来发送通知。以下就是几种通知的使用:

public class MainActivity extends Activity {

private NotificationManager manager;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//1.使用通知,先要获得一个通知管理器

manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

//点击此按钮发出一条通知(普通的通知)

findViewById(R.id.button1).setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Builder builder = new NotificationCompat.Builder(MainActivity.this);

builder.setSmallIcon(R.drawable.ic_launcher)

.setContentTitle("我是测试用的普通通知").setContentText("测试测试");

//当通知被点击的时候使用

Intent intent = new Intent();

intent.setClass(MainActivity.this, MainActivity.class);

//PendingIntent 等待的意图

PendingIntent intent2 = PendingIntent.getActivity(MainActivity.this, 0, intent, Notification.FLAG_AUTO_CANCEL);

builder.setContentIntent(intent2);

//通知点击以后消失

builder.setAutoCancel(true);

Notification notification = builder.build();

//发送通知

manager.notify(0,notification);

}

});

findViewById(R.id.button2).setOnClickListener(new OnClickListener() {

//进度通知

@Override

public void onClick(View v) {

new Thread(){

public void run() {

Builder builder = new NotificationCompat.Builder(MainActivity.this);

for (int i = 0; i <=100; i++) {

//progress当前进度

//indeterminate是否精确

builder.setProgress(100,i , false);

manager.notify(1,builder.build());

//必须设置setSmallIcon

builder.setSmallIcon(R.drawable.ic_launcher);

try {

Thread.sleep(200);

} catch (InterruptedException e) {

e.printStackTrace();

}

}

manager.cancel(1);

};

}.start();

}

});

findViewById(R.id.button3).setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Builder builder = new NotificationCompat.Builder(MainActivity.this);

builder.setSmallIcon(R.drawable.ic_launcher)

.setContentTitle("标题")

.setContentText("test");

BigPictureStyle style = new NotificationCompat.BigPictureStyle();

style.bigPicture(BitmapFactory.decodeResource(getResources(),R.drawable.c));

style.setBigContentTitle("通知");

builder.setStyle(style);

manager.notify(2, builder.build());

}

});

findViewById(R.id.button4).setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Builder builder = new NotificationCompat.Builder(MainActivity.this);

builder.setSmallIcon(R.drawable.ic_launcher);

RemoteViews views=new RemoteViews(getPackageName(),R.layout.notify_item);

views.setImageViewResource(R.id.iv, R.drawable.ic_launcher);

views.setTextViewText(R.id.tv,"自定义视图");

builder.setContent(views);

manager.notify(3,builder.build());

}

});

}

}
