android4.4 刷新相册,Android刷新本地相册

发现程序把图片保存到sdcard后,在相册里面找不到,只有在sdcard重新装载后会出现图片;

原来图片保存到本地后,需要通知相册,加上如下代码就好了:

Uri localUri = Uri.fromFile(imageFile);

Intent localIntent = new

Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, localUri);

sendBroadcast(localIntent);

imageFile是图片的File对象;

或者

ContentValues localContentValues = new ContentValues();

localContentValues.put("_data", imageFile.toString());

localContentValues.put("description", "save image ---");

localContentValues.put("mime_type", "image/jpeg");

ContentResolver localContentResolver = getContentResolver();

Uri localUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

localContentResolver.insert(localUri, localContentValues);
