Android DraerLayout 抽屉百分比适配屏幕宽度

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WindowManager wm = this.getWindowManager();//获取屏幕宽高
int width1 = wm.getDefaultDisplay().getWidth();
int height1 = wm.getDefaultDisplay().getHeight();
ViewGroup.LayoutParams para= mLl_two.getLayoutParams();//获取drawerlayout的布局
para.width=width1/3*2;//修改宽度
para.height=height1;//修改高度
mLl_two.setLayoutParams(para); //设置修改后的布局。
}
}
