java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child’s parent first问题解决

ViewPaper动态加载布局时出现如下错误：

```java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.                                                                      at android.view.ViewGroup.addViewInner(ViewGroup.java:3936)                                                                      at android.view.ViewGroup.addView(ViewGroup.java:3786)                                                                      at android.support.v4.view.ViewPager.addView(ViewPager.java:1413)                                                                      at android.view.ViewGroup.addView(ViewGroup.java:3727)                                                                      at android.view.ViewGroup.addView(ViewGroup.java:3700)                                                                      at com.zz.quicknews.fragment.HomeFragment$HomePagerAdapter.instantiateItem(HomeFragment.java:81)                                                                      at android.support.v4.view.ViewPager.addNewItem(ViewPager.java:943)                                                                      at android.support.v4.view.ViewPager.populate(ViewPager.java:1157)                                                                      at android.support.v4.view.ViewPager.populate(ViewPager.java:1025)                                                                      at android.support.v4.view.ViewPager$3.run(ViewPager.java:254)                                                                      at android.view.Choreographer$CallbackRecord.run(Choreographer.java:767)                                                                      at android.view.Choreographer.doCallbacks(Choreographer.java:580)                                                                      at android.view.Choreographer.doFrame(Choreographer.java:549)                                                                      at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:753)                                                                      at android.os.Handler.handleCallback(Handler.java:739)                                                                      at android.os.Handler.dispatchMessage(Handler.java:95)                                                                      at android.os.Looper.loop(Looper.java:135)                                                                      at android.app.ActivityThread.main(ActivityThread.java:5254)                                                                      at java.lang.reflect.Method.invoke(Native Method)                                                                      at java.lang.reflect.Method.invoke(Method.java:372)                                                                      at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:903)                                                                      at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

以上代码存在反复添加同一个view1的情况，而
这违反了AdapterView中The specified child already has a parent（已有父控件的子控件再次添加父控件）。
因此，可以按如下更改：

for (int i=0;i<tabTitleList.length;i++){            mTabLayout.addTab(mTabLayout.newTab().setText(tabTitleList[i]));            View view1=inflater.inflate(R.layout.item_gridview,null);            mViewList.add(view1);        }

更改后即可正常工作。
