[移动开发]android File和bitmap 相互转换

引用库implementation 'id.zelory:compressor:2.1.0'

转成Bitmap

 try {
                bitmap = new Compressor(activity)
                        .setMaxWidth(640)
                        .setMaxHeight(480)
                        .setQuality(75)
                        .setCompressFormat(Bitmap.CompressFormat.WEBP)
                        .setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory(
                                Environment.DIRECTORY_PICTURES).getAbsolutePath())
                        .compressToBitmap(file);
            } catch (IOException e) {
                e.printStackTrace();
            }

转成File

 try {
                        file2 = new Compressor(getContext())
                                .setMaxWidth(640)
                                .setMaxHeight(480)
                                .setQuality(75)
                                .setCompressFormat(Bitmap.CompressFormat.WEBP)
                                .setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory(
                                        Environment.DIRECTORY_PICTURES).getAbsolutePath())
                                .compressToFile(new File(picPath));
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
