//获取屏幕分辨率

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
String textStr = "手机屏幕的分辨率为：" + dm.widthPixels + "*" + dm.heightPixels;

//动态设置控件大小

WebView wv = (WebView)findViewById(R.id.wv);

LayoutParams laParams=(LayoutParams)wv.getLayoutParams();
laParams.height = (int) (dm.heightPixels*0.8);
wv.setLayoutParams(laParams);
