Eu tenho duas questões principais que estão intimamente ligadas. Eu estou olhando para esses problemas do ponto de vista programático.

(1) - Gostaria de fazer uma captura de tela do conteúdo de um layout ESPECÍFICO, ou seja, umScrollView aninhado em umLinearLayout.

(2) - Como oScrollView tem conteúdo que sai da tela (por isso, a rolagem é possível), como posso garantir que a captura de tela inclua os elementos que não estão visíveis na tela?

Este é o bloco atual de código que eu uso. Ele faz o trabalho de tirar uma captura de tela, mas apenas para a tela inteira.Isto é apesar deR.id.boss é o ID doScrollView e não o principalLinearLayout.

View view = findViewById(R.id.boss);
View v = view.getRootView();// this does not seem to make a difference
v.setDrawingCacheEnabled(true);                                                
v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());    
v.buildDrawingCache(true);
Bitmap b = Bitmap.createBitmap(u.getDrawingCache());             
v.setDrawingCacheEnabled(false);

Desde já, obrigado.

EDITAR:

Eu cometi alguns erros. eu useiR.id.boss qual é o recurso errado. Agora sou capaz de tirar uma captura de tela da rolagem sozinha, menos as partes fora da tela.
