在捕获textview图像时,阴影被破坏.

我使用setShadowLayer以编程方式添加了文本阴影.

tv.setShadowLayer(20, 0, 0, Color.BLACK);

当我用图像捕捉图像时

tv.buildDrawingCache(true);
tv.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
tv.setDrawingCacheEnabled(true);

并使用获取位图

bitmap = tv.getDrawingCache();

屏幕上的原始图像

捕获的图像

还尝试捕获父布局但结果相同.

我是android的新用户,我有一个android数据库连接并创建表应用程序,但在运行时它会生成一个错误.
听到错误:

我已经创建了 android_2.1 模拟器，当我运行任何应用程序时，几秒钟后控制台会产生这样的错误

是任何类型的错误并且可以解决此错误吗？
