Gets all controls of the specified type on the activity

Android gets all the child controls of the specified type, so that you do not need to use Findviewbyid to get the control one by one, to achieve the control state purpose.

/**  * 获取所有指定类型的子控件  * @param T  * @return  */privategetAllChildViews(Class<?> T) {  this.getWindow().getDecorView();  return getAllChildViews(view, T); }

privategetAllChildViews(View parent, Class<?> T) {  new ArrayList<View>();  ifinstanceof ViewGroup) {   ViewGroup vp = (ViewGroup) parent;   for (int0; i < vp.getChildCount(); i++) {    View viewchild = vp.getChildAt(i);    if (viewchild.getClass().equals(T)) {     allchildren.add(viewchild);    }    allchildren.addAll(getAllChildViews(viewchild, T));   }  }  return allchildren; }
