public void onClick(View v)     
{switch(v.getId())

    { case R.id.button1:

Answer 1

You can use this library to make it easy to do within a few lines of code -

 PdfGenerator.getBuilder()
                        .setContext(context)
                        .fromLayoutXMLSource()
                        .fromLayoutXML(R.layout.layout_print,R.layout.layout_print)
                        .setFileName("Test-PDF")
                        .build();

Answer 2

Maybe you can take a look on this link:

Instructions

1. create XML layouts

First create XML layouts. give it dimensions in pixels (and for all it's sub views) and proportions according landscape or portrait according to ratio 1:1.41.

page1.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="2115px"
            android:layout_height="1500px"
            android:background="@color/white">
 <TextView android:id="@+id/tv_hello"
            android:textColor="@color/black"
            android:textSize="27px"
            android:textStyle="bold"
            android:padding="6px"/>

</RelativeLayout>

you can create as many as pages/templates as you need.

2. Implement a View renderer

implement your View renderer by extending AbstractViewRenderer or by anonymously instantiating it and injecting the layout id. the initView(View view) will supply you an inflated View automatically. There are other options but I wont cover it now.

AbstractViewRenderer page = new AbstractViewRenderer(context, R.layout.page1) {
private String _text;

public void setText(String text) {
    _text = text;
}

@Override
protected void initView(View view) {
    TextView tv_hello = (TextView)view.findViewById(R.id.tv_hello);
     tv_hello.setText(_text);
}
};

// you can reuse the bitmap if you want
page.setReuseBitmap(true);

3. Build the PDF document

Use PdfDocument or PdfDocument.Builder to add pages and render and run it all at background with progress bar.

    PdfDocument doc            = new PdfDocument(ctx);

// add as many pages as you have
doc.addPage(page);

doc.setRenderWidth(2115);
doc.setRenderHeight(1500);
doc.setOrientation(PdfDocument.A4_MODE.LANDSCAPE);
doc.setProgressTitle(R.string.gen_please_wait);
doc.setProgressMessage(R.string.gen_pdf_file);
doc.setFileName("test");
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");
    }
});

doc.createPdf(ctx);

or use PdfDocument.Builder

new PdfDocument.Builder(ctx).addPage(page).filename("test").orientation(PdfDocument.A4_MODE.LANDSCAPE)
                         .progressMessage(R.string.gen_pdf_file).progressTitle(R.string.gen_please_wait).renderWidth(2115).renderHeight(1500)
                         .listener(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");
                             }
                         }).create().createPdf(this);
