[java] view plain copy print ?

1. public class ScanSdReceiver extends BroadcastReceiver  
2.     {  
3.         @Override    
4.         public void onReceive(Context context, Intent intent)  
5.         {  
6.             String action = intent.getAction();  
7.             if (Intent.ACTION_MEDIA_SCANNER_STARTED.equals(action))  
8.             {  
9.                 //开始扫描，把你的代码放这里   
10.             }  
11.             else if (Intent.ACTION_MEDIA_SCANNER_FINISHED.equals(action))  
12.             {  
13.                 //扫描结束，把你的代码放这里   
14.             }  
15.         }  
16.     }  

public class ScanSdReceiver extends BroadcastReceiver
    {
        @Override  
        public void onReceive(Context context, Intent intent)
        {
        	String action = intent.getAction();
            if (Intent.ACTION_MEDIA_SCANNER_STARTED.equals(action))
            {
            	//开始扫描，把你的代码放这里
            }
            else if (Intent.ACTION_MEDIA_SCANNER_FINISHED.equals(action))
            {
            	//扫描结束，把你的代码放这里
            }
        }
    }

 

注册广播接收机，监听SDcard扫描事件

[java] view plain copy print ?

1. IntentFilter intentfilter = new IntentFilter(Intent.ACTION_MEDIA_SCANNER_STARTED);  
2. intentfilter.addAction(Intent.ACTION_MEDIA_SCANNER_FINISHED);    
3. intentfilter.addDataScheme("file");    
4. ScanSdReceiver scanSdReceiver = new ScanSdReceiver();  
5. registerReceiver(scanSdReceiver, intentfilter);  

IntentFilter intentfilter = new IntentFilter(Intent.ACTION_MEDIA_SCANNER_STARTED);
intentfilter.addAction(Intent.ACTION_MEDIA_SCANNER_FINISHED);  
intentfilter.addDataScheme("file");  
ScanSdReceiver scanSdReceiver = new ScanSdReceiver();
registerReceiver(scanSdReceiver, intentfilter);
