How to set margin of ImageView using code, not xml

The question:

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?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

android.view.ViewGroup.MarginLayoutParams has a method setMargins(left, top, right, bottom). Direct subclasses are: FrameLayout.LayoutParams, LinearLayout.LayoutParams and RelativeLayout.LayoutParams.

Using e.g. LinearLayout:

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp.setMargins(left, top, right, bottom);
imageView.setLayoutParams(lp);

MarginLayoutParams

This sets the margins in pixels. To scale it use

context.getResources().getDisplayMetrics().density

DisplayMetrics

Method 2

    image = (ImageView) findViewById(R.id.imageID);
    MarginLayoutParams marginParams = new MarginLayoutParams(image.getLayoutParams());
    marginParams.setMargins(left_margin, top_margin, right_margin, bottom_margin);
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
    image.setLayoutParams(layoutParams);

Method 3

All the above examples will actually REPLACE any params already present for the View, which may not be desired. The below code will just extend the existing params, without replacing them:

ImageView myImage = (ImageView) findViewById(R.id.image_view);
MarginLayoutParams marginParams = (MarginLayoutParams) image.getLayoutParams();
marginParams.setMargins(left, top, right, bottom);

Method 4

Kevin’s code creates redundant MarginLayoutParams object. Simpler version:

ImageView image = (ImageView) findViewById(R.id.main_image);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(image.getLayoutParams());
lp.setMargins(50, 100, 0, 0);
image.setLayoutParams(lp);

Method 5

If you want to change imageview margin but leave all other margins intact.

  1. Get MarginLayoutParameters of your image view in this case: myImageView

     MarginLayoutParams marginParams = (MarginLayoutParams) myImageView.getLayoutParams();
    
  2. Now just change the margin you want to change but leave the others as they are:

     marginParams.setMargins(marginParams.leftMargin, 
                             marginParams.topMargin, 
                             150, //notice only changing right margin
                             marginParams.bottomMargin); 
    

Method 6

I use simply this and works great:

ImageView imageView = (ImageView) findViewById(R.id.image_id);
RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) imageView.getLayoutParams();
layoutParams.setMargins(left, top, right, bottom);
imageView.setLayoutParams(layoutParams);

setMargins()‘s unit is pixel not dp. If you want to set margin in dp, just inside your values/dimens.xml file create your dimensions like:

<resources>
    <dimen name="right">16dp</dimen>
    <dimen name="left">16dp</dimen>    
</resources>

and access like:

getResources().getDimension(R.dimen.right);

Method 7

You can use this method, in case you want to specify margins in dp:

private void addMarginsInDp(View view, int leftInDp, int topInDp, int rightInDp, int bottomInDp) {
    DisplayMetrics dm = view.getResources().getDisplayMetrics();
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    lp.setMargins(convertDpToPx(leftInDp, dm), convertDpToPx(topInDp, dm), convertDpToPx(rightInDp, dm), convertDpToPx(bottomInDp, dm));
    view.setLayoutParams(lp);
}

private int convertDpToPx(int dp, DisplayMetrics displayMetrics) {
    float pixels = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, displayMetrics);
    return Math.round(pixels);
}

Method 8

If you use kotlin, this can be simplified by creating an extension function

fun View.setMarginExtensionFunction(left: Int, top: Int, right: Int, bottom: Int) {
  val params = layoutParams as ViewGroup.MarginLayoutParams
  params.setMargins(left, top, right, bottom)
  layoutParams = params
}

Now all you need is a view, and this extension function can be used anywhere.

val imageView = findViewById(R.id.imageView)
imageView.setMarginExtensionFunction(0, 0, 0, 0)

Method 9

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)
}

Method 10

create layout dynamically and set its parameter as setmargin() will not work directly on an imageView

ImageView im;
im = (ImageView) findViewById(R.id.your_image_in_XML_by_id);
 RelativeLayout.LayoutParams layout = new RelativeLayout.LayoutParams(im.getLayoutParams());
                        layout.setMargins(counter*27, 0, 0, 0);//left,right,top,bottom
                        im.setLayoutParams(layout);
                        im.setImageResource(R.drawable.yourimage)

Method 11

For me this worked:

int imgCarMarginRightPx = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, definedValueInDp, res.getDisplayMetrics());

MarginLayoutParams lp = (MarginLayoutParams) imgCar.getLayoutParams();
lp.setMargins(0,0,imgCarMarginRightPx,0);
imgCar.setLayoutParams(lp);

Method 12

sample code is here ,its very easy

LayoutParams params1 = (LayoutParams)twoLetter.getLayoutParams();//twoletter-imageview
                params1.height = 70;
                params1.setMargins(0, 210, 0, 0);//top margin -210 here
                twoLetter.setLayoutParams(params1);//setting layout params
                twoLetter.setImageResource(R.drawable.oo);

Method 13

Using a method similar to this might save you some headaches in some situations.
If you have two passes of programmatical tinkering with margins it is safer to check if there are already some layoutParams set. If there are some margins already one should increase them and not replace them:

public void addMargins(View v, int left, int top, int right, int bottom) {
    LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) v.getLayoutParams();
    if (params == null)
        params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
                                               ViewGroup.LayoutParams.WRAP_CONTENT);
    int oldLeft = params.leftMargin;
    int oldTop = params.topMargin;
    int oldRight = params.rightMargin;
    int oldBottom = params.bottomMargin;
    params.setMargins(oldLeft + left, oldTop + top, oldRight + right, oldBottom + bottom);
    v.setLayoutParams(params);
}

Method 14

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);

Method 15

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)
            }

Method 16

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)
