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());
}
});
}
}
