应用内截屏的代码，在Activity中测试可用

        Display display = this.getWindowManager().getDefaultDisplay();
        view.layout(0, 0, display.getWidth(), display.getHeight());
        view.setDrawingCacheEnabled(true);// 允许当前窗口保存缓存信息，这样getDrawingCache()方法才会返回一个Bitmap
        Bitmap bmp = Bitmap.createBitmap(view.getDrawingCache());
        return bmp;
    }
}
