Answer 2

试试这个，应该好使
 // Tell the media scanner about the new file so that it is
            // immediately available to the user.
            MediaScannerConnection.scanFile(this,
                    new String[] { file.toString() }, null,
                    new MediaScannerConnection.OnScanCompletedListener() {
                public void onScanCompleted(String path, Uri uri) {
                    Log.i("ExternalStorage", "Scanned " + path + ":");
                    Log.i("ExternalStorage", "-> uri=" + uri);
                }
            });
祝你成功！

sendBroadcast(new  Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, data));

Answer 4

注意：Intent.ACTION_MEDIA_SCANNER_SCAN_FILE，是只扫描文件的，不会扫描文件夹的，得你自己查找指定文件private void scanSdCard(){
        String file= Environment.getExternalStorageDirectory().getAbsolutePath()+"/Photo";
        folderScan(file);
    }
    
    private void fileScan(String file){
        sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + file)));
    }
    
    private void folderScan(String path){
        File file = new File(path);
        
        if(file.exists() && file.isDirectory()){
            File[] array = file.listFiles();
            
            for(int i=0;i<array.length;i++){
                File f = array[i];
                
                if(f.isFile()){//FILE TYPE
                    String name = f.getName();
                    
                    if(name.endsWith(".mp4") || name.endsWith(".mp3") || name.endsWith(".jpg")){
                        fileScan(f.getAbsolutePath());
                    }
                }
                else {//FOLDER TYPE
                    folderScan(f.getAbsolutePath());
                }
            }
        }
    }
