Android获取屏幕宽度与长度的三个方法

1、WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);

int width = wm.getDefaultDisplay().getWidth();

int height = wm.getDefaultDisplay().getHeight();

 

 

2、WindowManager wm1 = this.getWindowManager();

int width1 = wm1.getDefaultDisplay().getWidth();

int height1 = wm1.getDefaultDisplay().getHeight();

        

       

3、DisplayMetrics dm = new DisplayMetrics();

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

int mScreenWidth = dm.widthPixels;// 获取屏幕分辨率宽度

int mScreenHeight = dm.heightPixels;
