Relative动态设置位置




relative里面有各种rightof之类的属性


如何在代码中动态改变


        if (screenWidth < 620) {
            RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) tv1.getLayoutParams();
            layoutParams.addRule(RelativeLayout.BELOW, R.id.tv1);
            layoutParams.leftMargin = DensityUtil.dip2px(ctx, 16);
            layoutParams.topMargin = DensityUtil.dip2px(ctx, 6);
            tv1.setLayoutParams(layoutParams);


        } else {


            RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) tv1.getLayoutParams();
            layoutParams.addRule(RelativeLayout.RIGHT_OF, R.id.tv1);
            layoutParams.topMargin = DensityUtil.dip2px(ctx, 12);
            tv1.setLayoutParams(layoutParams);
        }
