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;
