Sample for dynamically add or remove a view:

TextView tv = new TextView(this);

        tv.setWidth(LayoutParams.WRAP_CONTENT);

        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
        params.gravity = Gravity.RIGHT;
        tv.setLayoutParams(params);
        tv.setTextAppearance(this, R.style.darkTextNormal);
        tv.setBackgroundResource(R.color.lightBlue);
        tv.setTextSize(16);

yourLinearLayout.addView(tv);

// or

yourLinearLayout.removeView(tv);
