Question

I’m using dynamic layout I want to set width and height of a ImageView. The code is below. How can I set the height and width of an ImageView in a given layout? Any help is highly appreciated.

    RelativeLayout layout = new RelativeLayout(mContext);
    TextView text1 = new TextView(mContext);
    text1.setText(Constants.vctrCategory.elementAt(counter).toString());
    LayoutParams params1 = new    LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    params1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    text1.setLayoutParams(params1);
    text1.setTextSize(20);
    layout.addView(text1);
    ImageView image = new ImageView(mContext);
    image.setImageBitmap(bitmap);
    layout.addView(image);
    counter++;
    return layout;

Rather can calling calling addView() with just the ImageView, you could use the version that also takes two integers for the width and height:

addView(View child, int width, int height)

Alternatively, you can set the width and/or height directly on the view’s LayoutParams, i.e. after the layout.addView(image) call in your own snippet:

layout.addView(image);
layout.getLayoutParams().width = width;
layout.getLayoutParams().height = height;

Basically it’s similar to what you’re already doing for the TextView.
