Я вижу, что моя функция asynctaks * doinbackground * Есть betbackgrounddrawable и setbacktroundresource , которые не очень хорошо ... p>

Получил решение из проверенного ответа: < /p>

Я должен использовать новый запуск для изменения представлений внутри Doinbackround. < /p>

runOnUiThread(new Runnable() {
public void run() {

LinearLayout hatterLayout = (LinearLayout)findViewById(R.id.hatterLayout);
hatterLayout.setBackgroundResource(R.drawable.nonet);

}
