android屏幕截图

在android环境上截图

从其他地方看到的一段代码，然后写了示例程序，用来对屏幕截图

        // 获取指定Activity的截屏，保存到png文件  
        private static Bitmap takeScreenShot(Activity activity){  
        activity1 = activity;
        
        //View是你需要截图的View  
        View view = activity.getWindow().getDecorView();  
        view.setDrawingCacheEnabled(true);  
        view.buildDrawingCache();  
        Bitmap b1 = view.getDrawingCache();  
           
        //获取状态栏高度  
        Rect frame = new Rect();    
        activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);    
        int statusBarHeight = frame.top;    
        System.out.println(statusBarHeight);  
           
        //获取屏幕长和高  
        int width = activity.getWindowManager().getDefaultDisplay().getWidth();    
        int height = activity.getWindowManager().getDefaultDisplay().getHeight();    

        //去掉标题栏  
        Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight);  
        view.destroyDrawingCache();  
        return b;  
    }
