How to change the ImageView Height an Width

Question

I have created a new ImageView by Java code, but when I try to set height using setMaxHeight, its not working. Can someone help me to change the height of that ImageView?

ImageView i = new ImageView(MainActivity.this);
i.setImageResource(R.drawable.red);
i.setMaxWidth(50);
i.setMaxHeight(50);
ll.addView(i);

The easy way is to set the size programatically like that :

i.setLayoutParams(new LayoutParams(width, height));

if you want to change dp to pixel you can use this Code:

public static float pxFromDp(final Context context, final float dp) {
    return dp * context.getResources().getDisplayMetrics().density;
}

i.setLayoutParams(new LayoutParams(pxFromDp(this, 50), pxFromDp(this, 50)));

Use this code to set width and height.

ImageView iv = new ImageView(context);
int width = 60;
int height = 60;
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
