ViewPager 报错:Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child‘s parent first.

一中是removeView这个问题很常见的,具体解决方法就不谈了,另外一种是情况如下:

adapter=new ViewPagerAdapter(Views);

views>>  views集合  (我的方法)通过GuideView.getInstance(this).getView()得到的view》》views.addview(view)

当第一加载activity没问题不会报错,但是以后加载就报错

报错原因:

通过LayoutInflater实例化的一个布局(View)。当我第二次调用GuideView.getInstance(this).getView(),其实是被重复添加了两次。
             而一个View只能有一个父控件。当第二次添加的时候,又要改变这个控件的父控件(虽然是同一个父控件,但是也要通过改变该View的            父控件来实现)。运行时又不允许一个有父控件的子控件在有了一个父控件时,改变他的父控件。

错误代码:

	public static DepositView getInstance(Activity activity) {
		if(depositView==null){
			depositView = new DepositView(activity);
		}
		return depositView;
	}

修改后代码:

	public static DepositView getInstance(Activity activity) {
		        depositView = new DepositView(activity);
		return depositView;
	}

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView

?? java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first. 在android代码中假设出现此异常,说明在同一个布局中加入了同样的组件实例.应该创建不同的实例组件,并将其加入到布局其中.
