프로그래밍 방식으로 PercentRelativeLayout에서 percentHeight를 설정하는 방법

Question

PercentRelativeLayout의 높이를 백분율로 설정하고 싶습니다.

PercentRelativeLayout layout = new PercentRelativeLayout(this); 
     PercentRelativeLayout.LayoutParams llp = new PercentRelativeLayout.LayoutParams(PercentRelativeLayout.LayoutParams.MATCH_PARENT, 50%); 
     layout.setLayoutParams(llp); 

     myLayout.addView(layout); 

MatchParent 또는 Wrap_Content가 아닌 LayoutParams에서 percentHeight (50 %)를 사용한다고 가정합니다.

Answer 1

이 코드 :

LinearLayout rootLayout = (LinearLayout) findViewById(R.id.root); 
PercentRelativeLayout percentRelativeLayout = new PercentRelativeLayout(this); 
percentRelativeLayout.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent)); 
rootLayout.addView(percentRelativeLayout); 

Button button = new Button(this); 
percentRelativeLayout.addView(button); 
PercentRelativeLayout.LayoutParams params = (PercentRelativeLayout.LayoutParams) button.getLayoutParams(); 
PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo(); 
info.heightPercent = 0.5f;
