in your application.
public CheckoutButton getCheckoutButton(Context context, int style, int
textType);
Example code of getting the Payment button from the Library is:
CheckoutButton launchPayPalButton = ppObj.getCheckoutButton(this,
PayPal.BUTTON_278x43, CheckoutButton.TEXT_PAY);
RelativeLayout.LayoutParams params = new
RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
params.bottomMargin = 10;
launchPayPalButton.setLayoutParams(params);
launchPayPalButton.setOnClickListener(this);
((RelativeLayout)findViewById(R.id.RelativeLayout01)).addView(lau
nchPayPalButton);
