java - What is isInEditMode() and if(isInEditMode()) return; - 


  private void init()     {         if (isineditmode())             return;          paint.setstyle(paint.style.fill);         paint.setcolor(getresources().getcolor(r.color.control_highlight_color));         paint.setantialias(true);          setwillnotdraw(true);         setdrawingcacheenabled(true);         setclickable(true);     }

i ran above code while trying understand how ripple effect created.

1) question isineditmode(). have taken @ developer site , explanation little confusing me.

2) 1 if(isineditmode()) return; code strikes me odd. thought if statements check follow format if(){return;}. however, way code above formatted makes me confuse , know why so.

3) plus, if return value nothing why not not specifies in first place?

as have no answers #2 , #3, there is:

if have single instruction in if, can omit curly braces. plus java doesn't work indentation braces , semi-colons. can put single instruction on same line if, won't make differences, long there semi-colon.

for return;, method returns void, can't put object return. allows exit method, i.e. when have bad/unexpected value, return ends method moment called. return; means same return void; (however i'm don't know if compile).
