Android set button margin programmatically

Question

I know this question has been asked before, like this:

But my issue is when I do this:

LayoutParams params = new LayoutParams(
        LayoutParams.WRAP_CONTENT,      
        LayoutParams.WRAP_CONTENT
);
params.setMargins(left, top, right, bottom);

It shows there's no setMargins for params. Who can help?

Just add a line at last which is yourButton.setLayoutParams(params); — Pankaj

LayoutParams params = new LayoutParams(
            LayoutParams.WRAP_CONTENT,      
            LayoutParams.WRAP_CONTENT
    );
params.setMargins(left, top, right, bottom);

You are missing this line i guess

button.setLayoutParams(params);

You need to use this:

LinearLayout.LayoutParams or RelativeLayout.LayoutParams.

You are missing setLayoutParams(params) Attribute

    LayoutParams params = new LayoutParams(
        LayoutParams.WRAP_CONTENT,      
        LayoutParams.WRAP_CONTENT
);
params.setMargins(left, top, right, bottom);
Your_Layout.setLayoutParams(params);

I hope it will helps you .

For Kotlin do this:

val btn = Button(requireContext())
val lParams = LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.MATCH_PARENT,
              LinearLayout.LayoutParams.WRAP_CONTENT
         )
val marginInDp = 5.toPx() // 5dp
lParams.setMargins(marginInDp,marginInDp,marginInDp,marginInDp)

Watch for the size when setting margins. First I set 5 (px) and wondered why it's not working. Came out it was too little.

For those of you looking to do this with an existing Button, and existing parameters, to get the existing parameters and change them, you typecast the LayoutParams to the type of layout that the button is inside of:

//get the current params
ConstraintLayout.LayoutParams params = (ConstraintLayout.LayoutParams) button.getLayoutParams();
//change something in the params
params.setMargins(0, 0, 0, 200);
//set the button with the new params
button.setLayoutParams(params);
