Android初级教程：屏幕分辨率

不便一：下面代码中的getWidth和getHeight在adt上提示deprecated已经废弃了，实在扎眼

WindowManager wm = getWindowManager();      
Display display = wm.getDefaultDisplay();     
int screenWidth = display.getWidth();      
int screenHeight = display.getHeight(); 

    public static Point getSize(Activity act) {  
        Display display = act.getWindowManager().getDefaultDisplay();  
        Point size = new Point();  
        display.getSize(size);  //size.x就是宽度，size.y就是高度  
        return size;  
    }  

    public static Point getSize(Context ctx) {  
        WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);  
        Display display = wm.getDefaultDisplay();  
        Point size = new Point();  
        display.getSize(size);  
        return size;  
    }  

    public static Point getSizeNew(Context ctx) {  
        WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);  
        DisplayMetrics dm = new DisplayMetrics();  
        wm.getDefaultDisplay().getMetrics(dm);  
        Point size = new Point();  
        size.x = dm.widthPixels*dm.density;  
        size.y = dm.heightPixels*dm.density;  
        return size;  
    }  

    public static Point getSizeNew(Context ctx) {  
        WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);  
        DisplayMetrics dm = new DisplayMetrics();  
        wm.getDefaultDisplay().getMetrics(dm);  
        Point size = new Point();  
        size.x = dm.widthPixels;  
        size.y = dm.heightPixels;  
        return size;  
    }
