Android編程，有兩個按鈕控件，我想讓壹個占屏幕高度的90%，壹個占10%，怎麽實現？

//獲取屏幕尺寸

DisplayMetrics dm = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(dm);

int widthPixels = dm.widthPixels;

//獲取控件尺寸

LayoutParams params = (LayoutParams) imageView_base.getLayoutParams();

params.height = (int) (widthPixels * 0.57);

params.width = widthPixels;

//重設

imageView_base.setLayoutParams(params);

妳參考參考我的代碼，希望能幫到妳
