Android Imageview layoutparams in dip?

Question

I am using the following code:

ImageView i = new ImageView (mContext);

i.setImageResource (mImageIds [position]);

i.setScaleType (ImageView.ScaleType.FIT_XY);

//pixels settings !!! 

i.setLayoutParams (new gallery .LayoutParams (200, 100));

but, as you can see, it sets the dimensions of the layout in pixels.

Does anyone know how to do the same thing, but in "dip"?

Answer 1

See http://developer.android.com/guide/practices/screens_support.html#screen-independence

About how to convert from dpi to pixels.

Answer 2

The following helper method accepts input independent pixels (DIP) and returns the actual pixels for the current device.

 private int getPixels(int dipValue) { Resources r = getResources(); int px = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dipValue, r.getDisplayMetrics()); return px; } 

Answer 3

If you save your dimension as a resource, you can use

 getResources().getDimensionPixelSize(id); 

It will also simplify layout customization.
