Linearlayout programmatically - How to set up a divider?

问题

I am creating TextViews in LinearLayout programmatically and I would like to separate them with a divider (just a simple line). I have googled endlessly, what I have found is that I can use .setDividerDrawable, but I don't want to use external images for this. Any tips?

How to Add Divider to an Android Layout Programmatically

Create a View 1 or 2 pixels tall and width match_parent and set the background color to whatever color you want the divider to be.

Separate the divider from the items above and below with margin settings.

Example:

ImageView divider = new ImageView(this);
LinearLayout.LayoutParams lp = 
    new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
lp.setMargins(left, top, right, bottom);
divider.setLayoutParams(lp);
divider.setBackgroundColor(Color.WHITE);

You could use a simple drawable in xml for the divider (example here), or use a 9-patch image which barely takes anything.

Then, use the LinearLayoutICS in order to show the divider on most of the devices. you can check out this post i've made about it.

For linear layout you can use this attribute to set divider android:divider="some color" android:showDividers="middle"
