Answer 1

使用代码

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams( 
LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(30, 20, 30, 0);button.setLayoutParams(params);

Answer 2

final Button button = new Button(this);
LayoutParams params = new LayoutParams(
    LayoutParams.WRAP_CONTENT,      
    LayoutParams.WRAP_CONTENT
);
params.setMargins(left, top, right, bottom);
button.setLayoutParams(params);

Answer 3

您可以创建LinearLayout.LayoutParams的实例，为topMargin属性赋值并将该实例设置为按钮。希望有所帮助。
