android - Rotating an image, angle by angle, and waiting for refresh -

-

i'm trying rotate image full rotation, small angle-increment @ time.

each proceeding rotation should begin after previous rotation has been displayed.

how fast rotation happens means nothing me - long each rotation displayed it's fine me. means can practically considered "too fast".

i've tried few different approaches this. have working solution below (something along these lines, @ least - i've been playing code, might not compilable).

handler handler instance , of code below located in body of activity class i'm starting from. rotationincrement 0.36, we're "rotating" image 1000 times posting new runnable ui-thread each time previous rotation finished. 

public void start(view view) {     mainactivity.rotation=0;     imageview.setscaletype(scaletype.matrix);     handler.post(new rotationrunnable());        }  public class rotationrunnable implements runnable {         @override         public void run() {             mainactivity.rotation+=rotationincrement;             //log.d("rotating", string.valueof(rotation));             matrix matrix = new matrix(imageview.getimagematrix());             matrix.setrotate(rotation);             imageview.setimagematrix(matrix);             imageview.invalidate();              if (mainactivity.rotation<360) {                 handler.post(new rotationrunnable());             } else {                 log.d("elapsed", string.valueof((system.nanotime()-starttime)));             }         } }

the code above gives me pretty smooth "animation". 1000 rotations, takes 16s on samsung galaxy nexus finish.

my question this;

is there better way - if goal have rotation happen fast possible - , maintaining each rotation displayed in order?

this not going implemented product or - more artificial test, i'm not looking more "convenient" ways of animating rotation.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
