工作代码：
public static Bitmap getWholeListViewItemsToBitmap() { ListView listview = MyActivity.mFocusedListView; ListAdapter adapter = listview.getAdapter(); int itemscount = adapter.getCount(); int allitemsheight = 0; List<Bitmap> bmps = new ArrayList<Bitmap>(); for (int i = 0; i < itemscount; i++) { View childView = adapter.getView(i, null, listview); childView.measure(MeasureSpec.makeMeasureSpec(listview.getWidth(), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); childView.layout(0, 0, childView.getMeasuredWidth(), childView.getMeasuredHeight()); childView.setDrawingCacheEnabled(true); childView.buildDrawingCache(); bmps.add(childView.getDrawingCache()); allitemsheight+=childView.getMeasuredHeight(); } Bitmap bigbitmap = Bitmap.createBitmap(listview.getMeasuredWidth(), allitemsheight, Bitmap.Config.ARGB_8888); Canvas bigcanvas = new Canvas(bigbitmap); Paint paint = new Paint(); int iHeight = 0; for (int i = 0; i < bmps.size(); i++) { Bitmap bmp = bmps.get(i); bigcanvas.drawBitmap(bmp, 0, iHeight, paint); iHeight+=bmp.getHeight(); bmp.recycle(); bmp=null; } return bigbitmap;}
