Android获取所有指定类型的子控件,这样就不需要逐个使用findViewByID来获取控件,来达到控制状态的目的了。
/** * 获取所有指定类型的子控件 * @param T * @return */ private List<View> getAllChildViews(Class<?> T) { View view = this.getWindow().getDecorView(); return getAllChildViews(view, T); }
private List<View> getAllChildViews(View parent, Class<?> T) { List<View> allchildren = new ArrayList<View>(); if (parent instanceof ViewGroup) { ViewGroup vp = (ViewGroup) parent; for (int i = 0; i < vp.getChildCount(); i++) { View viewchild = vp.getChildAt(i); if (viewchild.getClass().equals(T)) { allchildren.add(viewchild); } allchildren.addAll(getAllChildViews(viewchild, T)); } } return allchildren; }
