setGravity after setMeasuredDimension is not work

Question

I created class customTextView extent TextView and I set textAlignment to center. In onMeasure I changed the textview width.

After that textview align change to left and I used this.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL); but it didn't change to center

Answer 1

add below code in your class.

Runnable runnable = new Runnable() {
            public void run() {
              view.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
            }
   };

Handler handler = new Handler();
handler.postDelayed(runnable,1000);

Answer 2

like this?

@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        ImageView imageView = (ImageView)((Activity) context).findViewById(R.id.list_r);
        int imageViewHeight = imageView.getMeasuredWidth();

        int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
        int parentHeight = MeasureSpec.getSize(heightMeasureSpec);

        int final_width = parentWidth - 2*imageViewHeight;
        this.setMeasuredDimension(final_width, parentHeight);

        Runnable runnable = new Runnable() {
            public void run() {
                view.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
            }
        };

        Handler handler = new Handler();
        handler.postDelayed(runnable,1000);
    }
