android - Image in LinearLayout not resizing well -

-

i have page called 'simpleresultpage'. in page display detail view different kind of items have in app.

at start of activity determine kind of items should display , based on hide/show viewstub's

currently try display image in betweent 2 textfields , code:

                <textview                     android:id="@+id/simple_result_text_title_1"                     style="@style/style_simple_result_title"/>                 <viewstub                     android:id="@+id/image1_viewstub"                     android:inflatedid="@+id/image1_inflated_viewstub1"                     style="@style/style_simple_result_image"                     android:layout="@layout/simple_list_image"/>                 <textview                     android:id="@+id/simple_result_text_text_1"                     style="@style/style_simple_result_text"/>

the style image this:

<style name="style_simple_result_image">     <item name="android:layout_height">wrap_content</item>     <item name="android:layout_width">fill_parent</item>     <item name="android:adjustviewbounds">true</item>     <item name="android:scaletype">center</item>     <item name="android:layout_gravity">center_horizontal</item>     <item name="android:layout_margintop">10dp</item>     <item name="android:layout_marginleft">20dp</item>     <item name="android:layout_marginright">20dp</item>     <item name="android:layout_marginbottom">20dp</item> </style>

but somehow image small , isn't showing way want (fill complete width , leave 20dp margin on both sides).

this ik looks right now: enter image description here

how should adjust code make way want it?

does changing line

 <item name="android:scaletype">center</item>

to

<item name="android:scaletype">center_inside</item>

make difference?

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
