從通知欄獲取通知

Question

我需要在我的設備中獲取已安裝的應用的未讀通知數。

例如：獲取Facebook應用程序，Whats應用程序應用程序或設備消息等的未讀通知計數，通知欄中存在的尚未讀取的任何內容。

據我所知，我會要求所有這些應用程序的內容URI。但是由於我不知道所有的URI，我該如何繼續這個。有沒有辦法通過從通知欄獲取所有通知？

package com.example.sampletest;

import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Intent; 
import android.os.Bundle; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
import android.widget.Toast; 

public class MainActivity extends Activity { 
    ListView l1; 
// public static int [] prgmImages={R.drawable.rlp, R.drawable.skp, R.drawable.ramesan, R.drawable.ramalingam, R.drawable.sweena}; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    l1 = (ListView)findViewById(R.id.list); 
    String[] values = new String[] {"ANDROID","Java","NETWORKING","ORACLE","DOTNET","VISUAL BASIC"}; 

// Define a new Adapter 
// First parameter - Context 
// Second parameter - Layout for the row 
// Third parameter - ID of the TextView to which the data is written 
// Forth - the Array of data 

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
R.layout.list_row, R.id.title, values); 


// Assign adapter to ListView 
l1.setAdapter(adapter); 
} 

@Override 
protected void onStart() { 
    // TODO Auto-generated method stub 
    super.onStart(); 
} 


@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 
    Toast.makeText(getApplicationContext(), "Back to foreground",Toast.LENGTH_SHORT).show(); 
} 

@SuppressWarnings("deprecation") 
@Override 
protected void onPause() { 
    // TODO Auto-generated method stub 
    super.onPause(); 
    createNotification(); 
    /* NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
     Notification notification = new Notification(R.drawable.ic_launcher, 
     "New Message", System.currentTimeMillis()); 

     Intent notificationIntent = new Intent(this, MainActivity.class); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, 
     notificationIntent, 0); 

     notification.setLatestEventInfo(MainActivity.this,"Message", 
     "RUNNING IN BACKGROUND", pendingIntent); 
     notificationManager.notify(9999, notification);*/ 

} 

@Override 
protected void onStop() { 
    // TODO Auto-generated method stub 
    super.onStop(); 
} 

@Override 
protected void onDestroy() { 
    // TODO Auto-generated method stub 
    super.onDestroy(); 
} 

@SuppressWarnings("deprecation") 
private void createNotification() { 

    NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
    int unique_id = 145558; 
    Intent nintent = new Intent(); 
    nintent.setClass(this, MainActivity.class); 

    PendingIntent pin = PendingIntent.getActivity(getApplicationContext(), 
      0, nintent, 0); 
    String title = "Notification"; 
    String body = "RUNNING IN BACKGROUND"; 
    Notification n = new Notification(R.drawable.ic_launcher, body, 
      System.currentTimeMillis()); 
    n.contentIntent = pin; 
    n.setLatestEventInfo(getApplicationContext(), title, body, pin); 
    n.flags |= Notification.FLAG_AUTO_CANCEL; 
    n.defaults = Notification.DEFAULT_ALL; 
    nm.notify(unique_id, n); 

}
