项目要求把统计图截屏分享，但是统计图有5个，上层为scrollview，在网上查询了并找到了解决方法：
[java]
/**
* 截取scrollview的屏幕
* **/
public static Bitmap getBitmapByView(ScrollView scrollView) {
int h = 0;
Bitmap bitmap = null;
// 获取listView实际高度
for (int i = 0; i < scrollView.getChildCount(); i++) {
h += scrollView.getChildAt(i).getHeight();
scrollView.getChildAt(i).setBackgroundResource(R.drawable.bg3);
}
Log.d(TAG, 实际高度: + h);
Log.d(TAG, 高度: + scrollView.getHeight());
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(scrollView.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
scrollView.draw(canvas);
// 测试输出
FileOutputStream out = null;
try {
out = new FileOutputStream(/sdcard/screen_test.png);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
try {
if (null != out) {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
// TODO: handle exception
}
return bitmap;
}
