// ConstraintLayout.LayoutParams linearParams =(ConstraintLayout.LayoutParams) imDanci.getLayoutParams(); //// 2.设置布局的高度 后面的参数就是对应xml中的 42dp 可以根据需要进行改变 // linearParams.height=((int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, ConstraintLayout.LayoutParams.WRAP_CONTENT, getResources().getDisplayMetrics())); //// 3.最后设置下控件的布局就可以了 // imDanci.setLayoutParams(linearParams); // RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); // lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE); //// lp.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE); // lp.height=(int)(bgHeight/5.5987558); // inflate.setLayoutParams(lp);
