How to set margin of ImageView using code, not xml

I want to add an unknown number of ImageView views to my layout with margin. In XML, I can use layout_margin like this:

<ImageView android:layout_margin="5dip" android:src="@drawable/image" />

There is ImageView.setPadding(), but no ImageView.setMargin(). I think it's along the lines of ImageView.setLayoutParams(LayoutParams), but not sure what to feed into that.

Does anyone know?

Answer from 2020 year :

dependencies {
    implementation "androidx.core:core-ktx:1.2.0"
}

and cal it simply in your code 

view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
   setMargins(5)
}

In Kotlin you can write it in more pleasant way

myView.layoutParams = LinearLayout.LayoutParams(
                RadioGroup.LayoutParams.MATCH_PARENT, RadioGroup.LayoutParams.WRAP_CONTENT
            ).apply {
                setMargins(12, 12, 12, 12)
            }

Here is an example to add 8px Margin on left, top, right, bottom.


ImageView imageView = new ImageView(getApplicationContext());

ViewGroup.MarginLayoutParams marginLayoutParams = new ViewGroup.MarginLayoutParams(
    ViewGroup.MarginLayoutParams.MATCH_PARENT,
    ViewGroup.MarginLayoutParams.WRAP_CONTENT
);

marginLayoutParams.setMargins(8, 8, 8, 8);

imageView.setLayoutParams(marginLayoutParams);

We can create Linear LayoutParams & use resources.getDimensionPixelSize for dp value.

    val mContext = parent.context
    val mImageView = AppCompatImageView(mContext)
    mImageView.setBackgroundResource(R.drawable.payment_method_selector)

    val height = mContext.resources.getDimensionPixelSize(R.dimen.payment_logo_height)
    val width = mContext.resources.getDimensionPixelSize(R.dimen.payment_logo_width)
    val padding = mContext.resources.getDimensionPixelSize(R.dimen.spacing_small_tiny)
    val margin = mContext.resources.getDimensionPixelSize(R.dimen.spacing_small)

    mImageView.layoutParams = LinearLayout.LayoutParams(width, height).apply {
        setMargins(margin, margin, 0, 0)
    }
    mImageView.setPadding(padding, padding, padding, padding)
