Answer 1

这是一个例子(改编自这个答案):

LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

params.setMargins(10, 20, 30, 40);

Button button = new Button(this);
button.setText("some text");
layout.addView(button, params);
