代碼設置控件居中

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
//此处相当于布局文件中的Android:layout_gravity属性
//            lp.gravity = priceShow ? Gravity.RIGHT : Gravity.LEFT;
lp.gravity = Gravity.LEFT;
tv_cabin_min_price.setLayoutParams(lp);
