print a view with a recyclerview

[fbertanha]

how can i print a view with a recyclerview ?

[jwhijazi]

I tried many times.
Recyclerview shows only items based on screen size.
to view all items use ListView with custom ArrayAdapter (this worked with me).

page1.xml (layout of the page).
`

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="100px"
    android:layout_marginTop="50px"
    android:orientation="vertical">
    <ListView
        android:id="@+id/lv_expensePerCategories"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >

    </ListView>

</LinearLayout>

` CustomAdapter.java ` public class CategoryExpensesListAdapter extends ArrayAdapter {

private Context context;
private List<MonthlyExpense> mData;

public CategoryExpensesListAdapter(Context context, int resource, ArrayList<MonthlyExpense> objects) {
    super(context, resource, objects);

    this.context = context;
    this.mData = objects;
}

public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.monthly_expenses_list_item, null);
    final MonthlyExpense me = mData.get(position);

    final TextView tv_catIcon;
    final ImageView img_catIcon;
    TextView tv_catName;
    CircleProgressView cpv_Percentage;
    TextView tv_categoryTotalAmount;

    tv_catIcon = view.findViewById(R.id.tv_catIcon);
    img_catIcon = view.findViewById(R.id.img_categoryIcon);
    tv_catName = view.findViewById(R.id.tv_catName);
    tv_categoryTotalAmount = view.findViewById(R.id.tv_categoryTotalAmount);
    cpv_Percentage = view.findViewById(R.id.cpv_Percentage);

    tv_categoryTotalAmount.setText(me.getAmount());
    tv_catName.setText(me.getCategoryName());
    tv_catName.setTextColor(Color.parseColor(me.getCategoryColor()));
    tv_catIcon.setTextColor(Color.parseColor(me.getCategoryColor()));

    return  view;
}

}

Code in main activity to generate PDF
`
final PdfDocument doc = new PdfDocument(context);

    Thread superThread = new Thread(new Runnable() {
        @Override
        public void run() {

            AbstractViewRenderer page = new AbstractViewRenderer(context, R.layout.page1) {

                private List<MonthlyExpense> expenses;

                @Override

                protected void initView(View view) {
                    
                   
                    listView = view.findViewById(R.id.lv_expensePerCategories);

                    expenses = new ArrayList<MonthlyExpense>();

                    //region Expenses per category
                    expenses = db.expenseDao().getMonthlyExpenses(month, year, -1);
                    ArrayAdapter<MonthlyExpense> adapter = new CategoryExpensesListAdapter(context, 0, (ArrayList<MonthlyExpense>) expenses);
                    listView.setAdapter(adapter);
                    //endregion
                }
            };

            doc.setRenderWidth(2480);
            doc.setRenderHeight(3508);
            doc.setOrientation(PdfDocument.A4_MODE.PORTRAIT);

            doc.addPage(page);
            
            doc.setSaveDirectory(context.getExternalFilesDir(null));
            doc.setInflateOnMainThread(false);

            doc.setListener(new PdfDocument.Callback() {
                @Override
                public void onComplete(File file) {
                    Log.i(PdfDocument.TAG_PDF_MY_XML, "Complete");
                }

                @Override
                public void onError(Exception e) {
                    Log.i(PdfDocument.TAG_PDF_MY_XML, "Error");
                }

            });
        }
    });
    
    superThread.start();
    doc.setProgressTitle(R.string.gen_please_wait);
    doc.setProgressMessage(R.string.gen_pdf_file);
    
    doc.setFileName("mytest_pdf");
    doc.createPdf(context);

I think the proble that the Recyclerview always recycle and reuse its view holders.
So when you scroll down , the previous page is not present at all (had been reused in the current page).
that is why you can't print

try this to stop recycling your views:

viewHolder.setIsRecyclable(false);

@tabebqena @fbertanha @jwhijazi @se-bastiaan @Arkar-Aung Hello, I'm maintaining a library whose concept is also based on this library. I think your issue will be solved with it. https://github.com/Gkemon/Android-XML-to-PDF-Generator
