public static int getScreenWidth(Activity ac) { // 获取屏幕的宽
   int width = ac.getResources().getDisplayMetrics().widthPixels;
   return width;
}
public static int getScreenHeight(Activity ac) {// 获取屏幕的高
   int height = ac.getResources().getDisplayMetrics().heightPixels;
   return height;
}
调用方法
LinearLayout.LayoutParams llp = (LinearLayout.LayoutParams) line_inputpaypwd.getLayoutParams();
llp.width = getScreenWidth(getActivity());
line_inputpaypwd.setLayoutParams(llp);
