作者：猫腻@
喜在我的应用程序，我想提出在android的应用程序中，我必须采取当前活动的屏幕截图，并保存到SD卡。
有关，我用命名为下载一个菜单按钮，当我点击我想目前的活动保存到SD卡中下载。
现在我的问题是它保存到SD卡，但截图未来half.I要下载的整个屏幕，并保存到sdcard.how下载完整的活动。
任何人都可以请帮我如何解决这个问题。

试用低于code捕捉整个屏幕，并保存为位图：
视图V = view.getRootView（）;
v.setDrawingCacheEnabled（真正的）;
位图B = v.getDrawingCache（）;
。字符串抽= Environment.getExternalStorageDirectory（）的toString（）;
文件mypath中=新的文件（抽，print.jpg）;

解决方案
Try out below code to capture the whole screen and save as bitmap.:
View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, "print.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myPath);
b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
MediaStore.Images.Media.insertImage( getContentResolver(), b,
"Screen", "screen");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Hope this will help you.
