How to make space between LinearLayout children

Question

I am programatically adding custom views to a vertical LinearLayout  and I would like there to be some space between the views   I have tried adding  setPadding 0  1  0  1  to my CustomView constructor  but this doesn t seem to have any effect   Any advice    It was pointed out that I should use margins   Since I am dynamically adding views  I need to set the margins from code  not in xml    I believe the way to do this is below  but it isn t working   public class MyView extends View       public MyView  Context context                super context            MarginLayoutParams params   new MarginLayoutParams LayoutParams WRAP CONTENT   LayoutParams WRAP CONTENT           params setMargins 0  10  0  10           setLayoutParams params      Edit   I also tried using MarginLayoutParams as a parameter while adding the views to the Linear layout  as below    This also did not work   MarginLayoutParams params   new MarginLayoutParams linearLayout getLayoutParams     linearLayout setMargins 0  10  0  10   linearLayout addView view  params

An easy way to do it dynamically is to add padding to the children  You can just set it using  setPadding   on the object to be added  This example is adding an ImageView to a LinearLayout   LinearLayout userFeedLinearLayout    LinearLayout  findViewById R id userFeedLinearLayout   imageView setImageBitmap bitmap   imageView setPadding 0  30  0  30   userFeedLinearLayout addView imageView     The following image shows two ImageViews that have been added with padding

If your layout contain labels o some container for text  You can add at the end of each text   n  to split a line and make space between elements  Example     video  text  Video NR1    obj Titulo   n

You can get the LayoutParams of parent LinearLayout and apply to the individual views this way   LinearLayout LayoutParams lp   new LinearLayout LayoutParams ViewGroup LayoutParams WRAP CONTENT  ViewGroup LayoutParams WRAP CONTENT   lp setMargins 8 8 8 8      Take care that setMargins   take pixels as int data type So  convert to dp before adding values Above code will set height and width to wrap content  you can customise it
