I have an issue with the following error popping up whenever I try to create a layout programmatically:

I don't use FrameLayout anywhere, but I guess it's something to do with ScrollView being added to the layout. I tried taking out the ScrollView and no errors appear.
Code:
private void createLayout(WaiterApp app, Order order) {
LinearLayout layout = this;
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, 585, 0.5f);
params.setMargins(10, 0, 10, 10);
layout.setLayoutParams(params);
layout.setOrientation(VERTICAL);
TextView title = new TextView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 125);
title.setBackgroundColor(getResources().getColor(R.color.colorButton, null));
title.setLayoutParams(params);
title.setGravity(Gravity.CENTER);
title.setTextAlignment(TextView.TEXT_ALIGNMENT_TEXT_START);
title.setTextColor(getResources().getColor(R.color.colorTextSecondary, null));
// Format a text
String text;
User servedBy = app.getDB().getUser(order.getWaiterID());
text = "<p> <b>" + getResources().getString(R.string.table_no) + "</b> " + order.getTable().toString() + "<br />"
+ "<b>" + getResources().getString(R.string.waiter_name) + "</b> " + servedBy.getFirstName() + " " + servedBy.getLastName() + "<br />"
+ "<b>" + getResources().getString(R.string.status) + "</b> " + order.getStatus() + "</p>";
// Assign the text
title.setText(Html.fromHtml(text, Html.FROM_HTML_MODE_LEGACY));
layout.addView(title);
// Body
LinearLayout body = new LinearLayout(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 460);
body.setLayoutParams(params);
body.setBackgroundColor(getResources().getColor(R.color.colorButtonSelected, null));
ScrollView scrollView = new ScrollView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
scrollView.setLayoutParams(params);
scrollView.setFillViewport(true);
scrollView.setPadding(0, 0, 0, 20);
TextView body_text = new TextView(app.getApplicationContext());
ScrollView.LayoutParams body_params = new ScrollView.LayoutParams(ScrollView.LayoutParams.MATCH_PARENT, ScrollView.LayoutParams.WRAP_CONTENT);
body_params.setMargins(10, 0, 10, 10);
body_text.setLayoutParams(body_params);
body_text.setTextColor(getResources().getColor(R.color.colorTextSecondary, null));
// Format text based on items that belong to the order
StringBuilder sb = new StringBuilder();
ArrayList<OrderItem> items = app.getDB().getOrderItems(order.getID());
for (OrderItem i : items) {
Item item = app.getDB().getItem(i.getItemID());
// First line
sb.append(i.getQuantity());
sb.append("x ");
sb.append(item.getName());
// Second line
if (i.getComment().length() != 0) {
sb.append("\n");
sb.append("(");
sb.append(i.getComment());
sb.append(")");
}
sb.append("\n\n");
}
body_text.setText(sb);
scrollView.addView(body_text);
body.addView(scrollView);
layout.addView(body);
// Remove order button (only shows if order was placed by the same user)
if (order.getWaiterID() == app.getUser().getID()) {
// Make body_text smaller
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 400);
params.setMargins(10, 135, 10, 0);
body_text.setLayoutParams(params);
TextView remove_text = new TextView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 80);
params.setMargins(0, 505, 0, 0);
remove_text.setLayoutParams(params);
remove_text.setBackgroundColor(getResources().getColor(R.color.colorRed, null));
remove_text.setTextSize(15);
remove_text.setTextColor(getResources().getColor(R.color.colorWhite, null));
remove_text.setGravity(Gravity.CENTER);
remove_text.setText(getResources().getString(R.string.order_remove));
layout.addView(remove_text);
}
}
The layout created by the function is added as a child to another LinearLayout. If someone could explain what I'm doing wrong I would appreciate it a lot. At the moment I just can't see where I've gone wrong.
