Set width & height with dp :

imageview.getLayoutParams().height = (int) getResources().getDimension(R.dimen.imageview_height);
imageview.getLayoutParams().width = (int) getResources().getDimension(R.dimen.imageview_width);

In your dimens.xml provide values for the keys :

<dimen name="imageview_width">50dp</dimen> 
<dimen name="imageview_height">50dp</dimen>

Use display metrics to get the sale factor and then just some simple maths - example, if I want 200x150dp:

final float scale = getResources().getDisplayMetrics().density;
int dpWidthInPx  = (int) (200 * scale);
int dpHeightInPx = (int) (150 * scale);

Then set the image view size:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(dpWidthInPx, dpHeightInPx);
imageView.setLayoutParams(layoutParams);

This may be simpler and should do the trick:

ImageView im = (ImageView)findViewById(R.id.image1);
LayoutParams params = im.getLayoutParams();
params.height = getActivity().getResources().getDimensionPixelSize(R.dimen.item_height);
params.width = getActivity().getResources().getDimensionPixelSize(R.dimen.item_width);

And in your dimens.xml

<dimen name="item_height">80dp</dimen> 
<dimen name="item_width">80dp</dimen>

Why do you say "simpler"? I don't see any neatness or simplicity in this... – doctorram Jun 08 '21 at 04:45

This may help you...

ImageView im = (ImageView)findViewById(R.id.image1);
LayoutParams params = im.getLayoutParams();
params.height = 100;
params.width = 100;

DisplayMetrics metrics = getWindowManager().getDefaultDisplay().getMetrics(metrics); float logicalDensity = metrics.density; int px = (int) (dp * logicalDensity + 0.5); this may help u in converting pixels to dp – lalith Jan 06 '14 at 11:48
Lalith does the 0.5 stays a common factor for all devices or it will be different.. – Karthik Jan 06 '14 at 11:57
please select this answer as correct, if it satisfies ur question – lalith Jan 06 '14 at 12:21

at first choose a desirable dip and assign it to a var.

int dipAmount=350;

Then read the height of your ImageView.

float scale = imageview.Resource.DisplayMetrics.Density;

Convert from px to dip.

int converter =(int) (350 * scale + 0.5f);

Set the height to imageview.

imageView.LayoutParameters.Height=converter;

 final float scale = getContext().getResources().getDisplayMetrics().density;
int height_ = (int) (250 * scale + 0.5f);
int width_ = (int) (250 * scale + 0.5f);

250 is in dp

ViewGroup.LayoutParams params = ImageView.getLayoutParams();
params.height = height_;
params.width = width_;

ImageView.setLayoutParams(params);

Try this:

image_view.getLayoutParams().height = 20;
image_view.getLayoutParams().width= 20;

Give me your feedback if it's acceptable. It's work for me.
