How do I programatically add a line below a textview layer

Question

I am looking to add a line below a textView programmatically in java and not in xml. I have the textView as follows:

textView.setText(DisplayName);

How do I go about the same? I have a textview supporting text and checkbox and I would like ot add a line below the same. Any clue?

Thanks! Justin

If you mean you just want a 2nd line of text in that textbox, just do DisplayName+"\n"+second_string. If you want to add in a new textView below this one, you'll need to create one via new and add it to the parent of this with the correct layout parameters. — Gabe Sechan, Jul 29 '13 at 14:45
Can you show me via code, how to set a line below a textview, with something like textview.setlinebelow( r.drawable.line) — , Jul 29 '13 at 14:47

You are probably looking for a separator. You could achieve this by 'faking' a line-seperator. add a normal View to your parent view with a height of 1dp.

Android - Dynamically Add Views into View

If you load a view from xml and want to add the line programmatically:

LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

ViewGroup layout = vi.inflate(R.layout.MyParentLayout, null);

View separator = new View(Context context);

set the view its layoutparams set its height: http://developer.android.com/reference/android/view/View.html#setLayoutParams(android.view.ViewGroup.LayoutParams)

layout.addView(separator);

If you create your layout programmatically:

new LinearLayout layout = new LinearLayout(context);` //or whatever kind of layout you want

I am writing this post on my mobile phone so it could contain some errors.

Add line view to the parent layout after textview.

View ruler = new View(myContext); ruler.setBackgroundColor(0xFF00FF00);
parentLayout.addView(ruler, new ViewGroup.LayoutParams( ViewGroup.LayoutParams.FILL_PARENT, 2));

It shows error on myContext and parentLayout(where it asks me to create the same fields). Can you please suggest a way to fix the same or what myContext is with respect to my code? Thanks – Jul 29 '13 at 15:09

If you're trying to underline the text, try this (from https://stackoverflow.com/a/10947374/413254):

textview.setPaintFlags(textview.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

If you're trying to create a divider of sorts, go with what RajaReddy suggested.
