如何在運行時設置PercentFrameLayout子視圖的百分比高度/寬度

Question

我想以編程方式設置子視圖的PercentFrameLayout高度/寬度。如何在運行時設置PercentFrameLayout的子視圖的百分比高度/寬度..

Answer 1

我假設您的PercentLayout中包含View with ID view_child。

所以使用這個代碼片斷

View view = findViewById(R.id.view_child); 
PercentRelativeLayout.LayoutParams params =(PercentRelativeLayout.LayoutParams) view.getLayoutParams(); 
// This will currently return null, if view not exist in your xml. 
PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo(); 
info.heightPercent = 0.60; 
view.requestLayout(); 

希望這有助於..

Answer 2

ImageView child= new ImageView(getActivity()); 

percentRelativeLayout.addView(child); 

PercentRelativeLayout.LayoutParams params = (PercentRelativeLayout.LayoutParams) child.getLayoutParams(); 

PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo(); 

info.heightPercent = 0.05f; 
info.widthPercent = 0.05f; 
info.leftMarginPercent = 0.5f; 
child.setLayoutParams(params);
