Android获取屏幕宽度高度

方法一:

 

WindowManager wm = (WindowManager) this
                .getSystemService(Context.WINDOW_SERVICE);
        int width = wm.getDefaultDisplay().getWidth();
        int height = wm.getDefaultDisplay().getHeight();

 

方法二:

WindowManager wm1 = this.getWindowManager();
        int width1 = wm1.getDefaultDisplay().getWidth();
        int height1 = wm1.getDefaultDisplay().getHeight();

 

方法一与方法二获取屏幕宽度的方法类似,只是获取WindowManager 对象时的途径不同。

 

方法三:

WindowManager manager = this.getWindowManager();
        DisplayMetrics outMetrics = new DisplayMetrics();
        manager.getDefaultDisplay().getMetrics(outMetrics);
        int width2 = outMetrics.widthPixels;
        int height2 = outMetrics.heightPixels;

 

方法四:

Resources resources = this.getResources();
        DisplayMetrics dm = resources.getDisplayMetrics();
        float density1 = dm.density;
        int width3 = dm.widthPixels;
        int height3 = dm.heightPixels;

 

方法三与方法四类似。
