Hello rmeph,

this probably happens because your surrounding LinearLayout is defined with:

Using xml Syntax Highlighting

android:layout_height="wrap_content" 
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

and the height of such a LinearLayout is the sum of all its children. So in this case, as you define the Child: ImageView with 'only' 50dip.

Replacign above with this line should do the job.

Hello rmeph,

this line:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

iv.setImageDrawable(getResources().getDrawable(R.drawable.x)); 
Parsed in 0.034 seconds,  using GeSHi 1.0.8.4

"overrides" what you defined in your xml.
Both functions you used are equivalent.

I don't know, if android:background is possible on ImageView, you should test that.
