android - Getting bitmap size in pixels on screen, not the actual size? -


i have layout has horizontal scroll on top, text box on bottom , whatever space left in middle fill imageview. in imageview load bitmap. let's call imageview bottom one.

now, on top of imageview load dynamically imageview user can move dragging it. second imageview (top one) has small icon in overlayed on top of bitmap , saved. think of logo/watermark.

both imageviews in relativelayout, can move top layout around.

now problem have can not size of bitmap loaded in bottom imageview.

i have tried following:

displaymetrics om = new displaymetrics(); getwindowmanager().getdefaultdisplay().getmetrics(om); tv.settext("w:" + b.getscaledwidth(om) + " h:" + b.getscaledheight(om));

but won't work, b.getscaledwidth(om) returns actual width of bitmap , not 1 on screen, should (in case of landscape image) 480px, size of screen of phone testing on.

additional info: why need because image show in bottom imageview not of same proportions imageview. can size of imageview imageview larger image itself. need keep top imageview inside boundaries of image shown in bottom imageview need know size of image in bottom imageview , not size of bottom view itself.

any ideas doing wrong?

i did not find way did "manually".

i extended imageview class myimageview class , in onmeasure override have calculated scale factor , accordingly created rect representing boundaries in coordinates according relativelayout, inside of myimageview.

i went way because found post here referred creating own imageview class, can't find link anymore.

anyway, after check top/left positioning of top imageview , set maximum location while moving around in ontouch method.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
