Call to `getDrawingCache` returns null when scroll is enabled

android, drawingcache, view

Solution

I solved it. Created a bitmap of view size and drew the view into it.

TableLayout page = (TableLayout) findViewById(R.id.page);
Bitmap pageBmp = Bitmap.createBitmap(page.getWidth(), page.getHeight(), 
                                       Config.ARGB_8888);
Canvas canvas = new Canvas(pageBmp);
page.draw(canvas);

Used the `pageBmp` bitmap..

Problem

What is missing in this code? This same code works on ICS. On API 8 the scroll appears and some content goes out of screen. How to get the drawing cache in this case? Code: ``` TableLayout page = (TableLayout) findViewById(R.id.page); page.setDrawingCacheEnabled(true); page.buildDrawingCache(); // getDrawingCache returns null... Bitmap pageBmp = Bitmap.createBitmap(page.getDrawingCache(true)); page.destroyDrawingCache(); page.setDrawingCacheEnabled(false); ```
