动态设置控件的高度和权重

最近遇到在代码里动态设置控件高度和权重

代码如下

1.动态设置控件高度：

设置一张图片高度ImageView

 ViewGroup.LayoutParams params = ImageView.getLayoutParams();
            params.height = height;
            ImageView.setLayoutParams(params);

当然也可以用

LinearLayout.LayoutParams paramsWeight = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
            paramsWeight.height = 1;

不过这两种具体使用适自己情况来定

2.动态设置控件权重：

设置testview权重

 LinearLayout.LayoutParams paramsWeight = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
            paramsWeight.weight = 1;
            testview.setLayoutParams(paramsWeight);
