动态添加LinearLayout的高度实例-创新互联

实例如下：

WindowManager wm = (WindowManager) getContext()
        .getSystemService(Context.WINDOW_SERVICE);
    int width = wm.getDefaultDisplay().getWidth();
    int height = (int) (width - 22*density) / 3;
    LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) mLinearLayoutTrafficControl.getLayoutParams();
    lp.height = height;
    LinearLayout.LayoutParams lp2 = (LinearLayout.LayoutParams) mLinearLayoutTrafficControl2.getLayoutParams();
    lp2.height = height;
   LinearLayout.LayoutParams lp3 = (LinearLayout.LayoutParams) mLinearLayoutTrafficServicesBusinessOnline.getLayoutParams();
    lp3.height = height;
