android - How can I make the transparent part of an image not show up -


in android, animating 2 images 1 small on top of larger one. small generated using photoshop , visible part surrounded checkerboard pattern (which supposed transparent). when animation runs, images appear checkerboard patters shows grey square.

how can make transparent.

this how imagebutton setup in layout.xml

 <imagebutton android:layout_gravity="top|left" android:layout_marginleft="184dp" android:layout_margintop="55dp" android:id="@+id/videothumb" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/button_power_on" />

and animation file:

 <?xml version="1.0" encoding="utf-8"?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:fromalpha="0.0" android:toalpha="0.8" android:duration="5000" android:repeatmode="reverse" android:repeatcount="infinite" />

i think it's because using imagebutton , grey color see default background of button. use imageview instead.

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
