我可以以编程方式截取主屏幕，而无需root我的Android设备吗？

Question

I want to take screenshot of my home screen .How can I achieve this ? I am able to take screenshots of current activity but not the home screen .

My codes for taking screenshot of current activity is

View v1 = linearlayout_var.getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bm = v1.getDrawingCache();
BitmapDrawable bitmapDrawable = new BitmapDrawable(bm);
imageview.setBackgroundDrawable(bitmapDrawable);

If i want to take the screenshot of Home screen ,what I should use instead of linearlayout_var so that I can reach the root view of home screen .

In single line my question is how to get the root view of Homescreen ??

Try this one

getWindow().getDecorView().findViewById(android.R.id.content);

Hope it helps.
