来自其他类的方法的调用状态栏通知

Question

首先，我对android和Java都很陌生。

我有两个类，我的main.class和Note.class。

我在我的main.class的Note.class中调用通知方法，当我按下按钮时。

的问题是与这条线从Note.class：

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 

notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 

当方法被调用它强行关闭。我相信问题是PendingIntent.getActivity（this，0，notificationIntent，0）中的“this”，但我不确定要将其更改为。

通知代码在主类中正常工作。

我将非常感谢任何指导。

Note.class：

package com.adamblanchard.remindme.com.adamblanchard; 

import com.adamblanchard.remindme.R; 
import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 



public class Note extends Activity { 

public CharSequence note = "not changed"; 
int HELLO_ID = 1; 

/** Called when the activity is first created. */ 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    setTitle("Remind Me!"); 


} 

//Notification Method 

public void callNotification() { 
    // TODO Auto-generated method stub 


    String ns = Context.NOTIFICATION_SERVICE; 
    final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); 

    int icon = R.drawable.launcher; 
    CharSequence tickerText = "Remind Me!"; 
    long when = System.currentTimeMillis(); 

    final Notification notification = new Notification(icon, tickerText, when); 

notification.flags |= Notification.FLAG_AUTO_CANCEL; 

final Context context = getApplicationContext(); 
CharSequence contentTitle = "Remind Me!"; 
CharSequence contentText = note; 

Intent notificationIntent = new Intent(context, AndroidNotifications.class); 
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 

notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 





     mNotificationManager.notify(HELLO_ID, notification); 

     HELLO_ID++; 
} 

} 

调试输出：

螺纹[< 1>主]（暂停（例外IllegalStateException异常） ）
注意（Activity）.getSystemService（String）行：3536
Note.callNotification（）线：37
remindme $ 1 $ 1.onClick（DialogInterface，INT）线：72 AlertDialog（AlertController $ ButtonHandler）.handleMessage（消息）线：159 AlertController $ ButtonHandler（处理程序）。调用Message（Message）行：99
Looper.loop（）line：123 ActivityThread.main（String []）line：3647
Method.invokeNative（Object，Object []，Class，Class []，Class，int ，布尔值）行：不可用[本地方法]

ZygoteInit $ MethodAndArgsCaller.run（）line：839
ZygoteInit.main（字符串[]）线：597 NativeStart.main（字符串[]）行：不可用[本机方法]

这是调试输出我得到的，再加上强制关闭弹出装置。

Answer 1

OK！我修好了它！

在manifest.xml我需要使用全名的活动，即：

<activity android:name=".com.adamblanchard.Note"></activity> 

我已经与代码瞎搞，所以其他的事情可能只要我做出了贡献，但改变了它的工作。

Answer 2

在你remindme活动，你有下面这行： Note Note = new Note();

这是不是实例化一个Activity正确方式。您应该创建一个Intent：

Intent myIntent = new Intent(this, Note.class); 

，并把它传递给startActivity。
