Android获取屏幕宽高

 private void getScreenSize(){
        DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);
        int width = metrics.widthPixels;//宽度 px
        int height = metrics.heightPixels;//高度 px
        float density = metrics.density;//密度 0.75/1.0/1.5
        int densityDpi = metrics.densityDpi;//密度dpi(120/160/240)
        int screenW = (int)(width/density);//屏幕宽度(dp)
        int screenH = (int)(height/density);//屏幕高度(dp)
        LogUtils.i("width:"+width+"   height:"+height+"   density:"+density+"  densityDpi:"+densityDpi+"  screenW:"+screenW+"  screenH:"+screenH);
    }
