您可以使用其更改Button（或任何其他View）的大小LayoutParams

// obtaining reference to view, e.g. in Activity
Button b = findViewById(R.id.sbi_button); 

// setting new size
int newSize = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 60,
            getResources().getDisplayMetrics()); // 60dp to px unit
b.getLayoutParams().width = newSize; // setting new width and height
b.getLayoutParams().height = newSize;
b.requestLayout(); // force remeasure and redraw, may not be needed
