Android实现获取手机相册里面的所有图片

获取手机相册里所有会显示的图片,并不是手机所有的图片

   		String selection = MediaStore.Images.Media.BUCKET_ID + " = ?";
        String bucketId = String.valueOf(id);
        String sort = MediaStore.Images.Media._ID + " DESC";
        String[] selectionArgs = {bucketId};

        Uri images = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        Cursor c;
        if (!bucketId.equals("0")) {
            c = resolver.query(images, null, selection, selectionArgs, sort);	//查询带条件
        } else {
            c = resolver.query(images, null, null, null, sort);//查询所有
        }
        ArrayList<Uri> imageUris = new ArrayList<>();
        if (c != null) {
            try {
                if (c.moveToFirst()) {
                //c.getString(c.getColumnIndex(MediaStore.Images.Media.DATA) 完整路径名
                //c.getString(c.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME) 文件名
                    setPathDir(c.getString(c.getColumnIndex(MediaStore.Images.Media.DATA)),
                            c.getString(c.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME)));
                    do {
                        String mimeType = c.getString(c.getColumnIndex(MediaStore.Images.Media.MIME_TYPE));
                        //获取文件夹名  (DCIM,Camera)  不是完整路径 
                        String folderName = c.getString(c.getColumnIndex(MediaStore.Images.Media.BUCKET_DISPLAY_NAME));
                        if (isExceptMemeType(exceptMimeTypeList, mimeType)
                                || isNotContainsSpecifyFolderList(specifyFolderList, folderName)) continue;

                        int imgId = c.getInt(c.getColumnIndex(MediaStore.MediaColumns._ID));
                        //获取 uri
                        Uri path = Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + imgId);
                        imageUris.add(path);

                    } while (c.moveToNext());
                }
                c.close();
            } catch (Exception e) {
                if (!c.isClosed()) c.close();
            }
        }
        return imageUris;

private void setPathDir(String path, String fileName) {
        pathDir = path.replace("/" + fileName, "");	//获取文件路径
    }

相册显示的图片 需要加入以下代码

String path = "你图片的完整路径";
   // 其次把文件插入到系统图库
//                        try {
//                            MediaStore.Images.Media.insertImage(getContext().getContentResolver(), path, path.substring(path.lastIndexOf("/")+1), null);
//                        } catch (FileNotFoundException e) {
//                            e.printStackTrace();
//                        }
                    //需要通知相册更新了
                        getContext().sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + path)));
