基于Android实现保存图片到本地并可以在相册中显示出来

/** 首先默认个文件保存路径 */
private static final String SAVE_PIC_PATH=Environment.getExternalStorageState().equalsIgnoreCase(Environment.MEDIA_MOUNTED) ? Environment.getExternalStorageDirectory().getAbsolutePath() : /mnt/sdcard;//保存到SD卡
private static final String SAVE_REAL_PATH = SAVE_PIC_PATH+ /good/savePic;//保存的确切位置

public static void saveFile(Bitmap bm, String fileName, String path) throws IOException {
String subForder = SAVE_REAL_PATH + path;
File foder = new File(subForder);
if (!foder.exists()) {
foder.mkdirs();
}
File myCaptureFile = new File(subForder, fileName);
if (!myCaptureFile.exists()) {
myCaptureFile.createNewFile();
}www.jb51.net
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(myCaptureFile));
bm.compress(Bitmap.CompressFormat.JPEG, 80, bos);
bos.flush();
bos.close();
}

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri uri = Uri.fromFile(file);
intent.setData(uri);
context.sendBroadcast(intent);//这个广播的目的就是更新图库，发了这个广播进入相册就可以找到你保存的图片了！，记得要传你更新的file哦
