android - setGravity after setMeasuredDimension is not work -

i created class customtextview extent textview , set textalignment center. in onmeasure changed textview width.

after textview align change left , used this.setgravity(gravity.center_vertical | gravity.center_horizontal); didn't change center

add below code in class.

runnable runnable = new runnable() {             public void run() {               view.setgravity(gravity.center_vertical | gravity.center_horizontal);             }    };  handler handler = new handler(); handler.postdelayed(runnable,1000);
