android获得屏幕高度和宽度

android获取屏幕宽度和高度，需要用到WindowManager这个类

1、WindowManager windowManager= (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);
int screenWidth=windowManager.getDefaultDisplay().getWidth();
int screenHeight=windowManager.getDefaultDisplay().getHeight();
2、WindowManager windowManager=this.getWindowManager();
int screenWidth=windowManager.getDefaultDisplay().getWidth();
int screenHeight=windowManager.getDefaultDisplay().getHeight();
