我应用到的场景是程序中在视频通讯时截图,将截图保存到本地相册中
/*** @param bmp 获取的bitmap数据
* @param picName 自定义的图片名*/
public static void saveBmp2Gallery(Bitmap bmp, String picName) { String fileName = null; //系统相册目录 String galleryPath= Environment.getExternalStorageDirectory() + File.separator + Environment.DIRECTORY_DCIM +File.separator+"Camera"+File.separator; // 声明文件对象 File file = null; // 声明输出流 FileOutputStream outStream = null; try { // 如果有目标文件,直接获得文件对象,否则创建一个以filename为名称的文件 file = new File(galleryPath, picName+ ".jpg"); // 获得文件相对路径 fileName = file.toString(); // 获得输出流,如果文件中有内容,追加内容 outStream = new FileOutputStream(fileName); if (null != outStream) { bmp.compress(bmp_format, 90, outStream); } } catch (Exception e) { e.getStackTrace(); }finally { try { if (outStream != null) { outStream.close(); } } catch (IOException e) { e.printStackTrace(); }
}
//通知相册更新 MediaStore.Images.Media.insertImage(mContext.getContentResolver(), bmp, fileName, null); Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); Uri uri = Uri.fromFile(file); intent.setData(uri); mContext.sendBroadcast(intent); ToastUtil.show("图片保存成功"); }
