Android 长按照片保存 工具类

 

public class ImgUtils { public static void saveImageToGallery(Context context, Bitmap bmp) { final String[] items = new String[] { "保存图片"}; //图片转成Bitmap数组 final Bitmap[] bitmap = new Bitmap[1]; bitmap[0] = bmp; // Glide.with(context).load(url).asBitmap().into(new SimpleTarget<Bitmap>() { // @Override // public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) { // bitmap[0] = resource; // } // }); // 首先保存图片 创建文件夹 File appDir = new File(Environment.getExternalStorageDirectory(), "shy"); if (!appDir.exists()) { appDir.mkdir(); } //图片文件名称 String fileName = "shy_"+System.currentTimeMillis() + ".jpg"; File file = new File(appDir, fileName); try { FileOutputStream fos = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos); fos.flush(); fos.close(); } catch (Exception e) { e.printStackTrace(); } // 其次把文件插入到系统图库 String path = file.getAbsolutePath(); try { MediaStore.Images.Media.insertImage(context.getContentResolver(), path, fileName, null); } catch (FileNotFoundException e) { e.printStackTrace(); } // 最后通知图库更新 Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); Uri uri = Uri.fromFile(file); intent.setData(uri); context.sendBroadcast(intent); new ToastUtils(context).showToast("保存成功"); } }
