Hi, thanks a lot for your answer, it's helping a lot.
Last but not least I've got some differences on two real devices. First of all the XML: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="#fff"> <TextView android:id="@+id/tv" android:layout_width="340px" android:layout_height="71px" android:text="The Quick Brown Fox..." android:textSize="20px" android:background="#abcdef" android:textColor="#000" android:layout_marginBottom="20dip" /> <ImageView android:id="@+id/iv" android:layout_width="340px" android:layout_height="71px" android:background="#56789a" /> </LinearLayout> Now the new code: Bitmap bmp = Bitmap.createBitmap(340, 71, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bmp); TextView tv = new TextView(this); tv.setText("The Quick Brown Fox..."); tv.setTextSize(20.0f); tv.setBackgroundColor(Color.rgb(0xab, 0xcd, 0xef)); tv.setTextColor(Color.rgb(0x00, 0x00, 0x00)); tv.measure(340, 71); // !!! tv.layout(0, 0, 340, 71); // !!! tv.draw(canvas); ImageView iv = (ImageView) findViewById(R.id.iv); iv.setImageBitmap(bmp); On a HTC Magic (320x480) both views are the same. On a Nexus S the ImageView with the Bitmap with the TextView is much bigger than the pure TextView one. So I think it is a density isue. As the doc says the createBitmap already takes care of the Density. Playing with the factor 1.5 (= 240dpi / 160dpi) didn't help me out.
