在程序中我动态的创建了很多按钮，但是如何在两个按钮之间添加空间呢？我用这样的代码
但是没有实现，大家能帮助我吗？谢谢！

private LinearLayout LLDynamic;

 private RelativeLayout.LayoutParams ParaOne;

ParaOne = new RelativeLayout.LayoutParams(280, 30);

Button button1= new Button(Twindo_fromEditGroup.this);
button1.setTextSize(16);


LLDynamic = new LinearLayout(Twindo_fromEditGroup.this); 
LLDynamic.setOrientation(LinearLayout.VERTICAL);
LLDynamic.addView(button1,ParaOne);

Answer 1

使用以下代码添加空白：

Button button1 = new Button(this);
LinearLayout.LayoutParams rel_button1 = new LinearLayout.LayoutParams(buttonWidth, buttonHeight);
rel_button1.setMargins(20, 0, 0, 0);
button1.setLayoutParams(rel_button1);
