java - prevent gridView from expanding to fit landscape width -

-

i have gridview 4 columns of imgs. when phone turned landscape layout, grids of gridview expand fill width, creating white spaces in between img although img stay @ desired width. there way keep grid view filling width of screen when in landscape layout ?

i have 2 methods that:

1) create layout each orientation:

res/layout/.... res/layout-land/....

2) 1 layout both vertical , horizontal orientation:

  • set gridview with: android:numcolumns="4"

  • your custom view item, set android:layout_width="match_parent"

with second method, may encount problem high of item. create custom view , override onmeasure.

for example: need linearlayout item , keep ratio height/width = 4.5/4, following custom:

public class mylinearlayout extends linearlayout {     //..... constructor methods     @override     protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {         int scaleheight =(int)( widthmeasurespec/4*4.5);         super.onmeasure(widthmeasurespec, scaleheight);     } }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
