Hi, It should,
how it works -> the calculation is like this, for example, in ur case display width (dw) - 640 display height (dh) - 480 video width (vw) - 320 video height (vh) - 240 these are done in onmeasure function in videoview widget case 1: vw*dh > vh*dw then, dh=(vh*dw)/vw; dw= no change case 2: vw*dh < vh*dw then, dw=(dh*vw)/vh; dh= no change case 3: if the above both cases not satisfied, (ie) vw*dh = vh*dw then dw and dh kept the same. finally, the video will be played at dw x dh. It works for me, my display size is 640x430. for testing, i kept android layoutwidth=352 and android layoutheight= 288 in movieview.xml when i play a 3gp video file (176x144) from browser through streaming, it plays at 352x288.
