How to convert Android View to PDF

Question

I have created an Android Invoice app. The generated invoice is standard Android layout with nested views. I am looking for a library that I can use to convert this view to

Answer 1

I made a library to achieve this objective (Getting PDF from Java View objects).

The main code snippet is -

 PdfGenerator.getBuilder()
                        .setContext(context)
                        .fromViewSource()
                        .fromView(targetView) /* "targetView" is the view ,you want to convert PDF */
            /* "fromLayoutXML()" takes array of layout resources.
             * You can also invoke "fromLayoutXMLList()" method here which takes list of layout resources instead of array. */
                        .setDefaultPageSize(PdfGenerator.PageSize.A4)
            /* It takes default page size like A4,A5. You can also set custom page size in pixel
             * by calling ".setCustomPageSize(int widthInPX, int heightInPX)" here. */
                        .setFileName("Test-PDF")
            /* It is file name */
                        .setFolderName("FolderA/FolderB/FolderC")
            /* It is folder name. If you set the folder name like this pattern (FolderA/FolderB/FolderC), then
             * FolderA creates first.Then FolderB inside FolderB and also FolderC inside the FolderB and finally
             * the pdf file named "Test-PDF.pdf" will be store inside the FolderB. */
                        .openPDFafterGeneration(true)
            /* It true then the generated pdf will be shown after generated. */
                        .build(new PdfGeneratorListener() {
                            @Override
                            public void onFailure(FailureResponse failureResponse) {
                                super.onFailure(failureResponse);
                /* If pdf is not generated by an error then you will findout the reason behind it
                 * from this FailureResponse. */
                            }

                            @Override
                            public void showLog(String log) {
                                super.showLog(log);
                /*It shows logs of events inside the pdf generation process*/ 
                            }

                            @Override
                            public void onSuccess(SuccessResponse response) {
                                super.onSuccess(response);
                /* If PDF is generated successfully then you will find SuccessResponse 
                 * which holds the PdfDocument,File and path (where generated pdf is stored)*/
                
                            }
                        });
