通知栏的最小代码

代码：

package com.example.custemviewtry;import javax.security.auth.PrivateCredentialPermission;import com.example.custemviewtry.view.GoodGame;import android.annotation.SuppressLint;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.SimpleAdapter.ViewBinder;public class MainActivity extends Activity implements OnClickListener{    private GoodGame goodGame;    private Notification.Builder mBuilder;    private NotificationManager notificationManager;    @Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        goodGame = (GoodGame) findViewById(R.id.goodgame);        notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);        initNotifcation();        goodGame.setOnClickListener(this);    }    @SuppressLint("NewApi")    private void initNotifcation()    {        mBuilder = new Notification.Builder(this);        mBuilder.setContentTitle("title").setContentText("this is text").setTicker("通知来了")                .setSmallIcon(R.drawable.ic_launcher).setContentInfo("this is info ");    }    @SuppressLint("NewApi")    @Override    public void onClick(View v)    {        notificationManager.notify(10, mBuilder.build());    }}

总结：

1，NotificationManager
2，Notification.Builder
3，mBuilder.setContent….
4，notificationManager.notify(id，mBuilder.build());

注意：

id是自己用就行了，不需要通告给别人，作用是如果statusBar已经存在相同id的通知，那么当前的就会替换以前的。
