Horizontal Scrolling

[finnp]

Hey,

I was wondering if you are open to adding horizontal scrolling to this module or if you want to keep it simple?

I'm asking because with PdfKit these things are quite trivial, but on Android it would require a few more adjustments.

Best,
Finn

Yeah, probably this will require a lot of work because of zoom of the RecyclerView.

+1 for horizontal scrolling. Anything we can help to make this happen?

I believe we'll need to do the following:

• Change the layout orientation:

  react-native-pdf-renderer/android/src/main/java/com/github/douglasjunior/reactNativePdfRenderer/modules/PdfRendererRecyclerView.java

  Line 79 in d3ba0cf

  mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);

• Update the page size and margin calculation:

  react-native-pdf-renderer/android/src/main/java/com/github/douglasjunior/reactNativePdfRenderer/modules/PdfRendererRecyclerView.java

  Lines 427 to 433 in d3ba0cf

  	if (mSinglePage) {
  	lp.height = LayoutParams.MATCH_PARENT;
  	lp.setMargins(0, 0, 0, 0);
  	} else {
  	lp.height = Math.round(((float) mWidth / (float) page.getWidth()) * (float) page.getHeight());
  	lp.setMargins(0, 0, 0, (int) mDistanceBetweenPages);
  	}

• Adjust horizontal scrolling to manage the scroll speed when zoomed in:

  react-native-pdf-renderer/android/src/main/java/com/github/douglasjunior/reactNativePdfRenderer/modules/PdfRendererRecyclerView.java

  Line 460 in d3ba0cf

  class LayoutManager extends LinearLayoutManager {

• Perform regression tests to ensure that everything is working properly and nothing is broken.
