開發過程稱遇到各種錯誤，很少頭疼，下面貼下我遇到的錯誤：
java.lang.IllegalArgumentException: Binary XML file line #676: Duplicate id 0x7f0f02a6, tag null, or parent id 0xffffffff with another fragment for com.example.yuanmu.lunbo.Custom.CycleViewPager
這個說的是我引入的佈局的ID重複了，所以報錯，下面貼日誌：

下面是我的部分代碼：
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mContext = container.getContext();
view = (ViewGroup) inflater.from(mContext).inflate(R.layout.lifecircle_ranking_fragment, container, false);
return view;
}
我的佈局是Fragment再添加個Fragment，也就是Fragment裏有輪播圖，輪播放也是用Fragment做的
看了錯誤日誌，可以這樣改：
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mContext = container.getContext();
//view不爲空時才加載佈局，不然會重複的ID,報錯
view = (ViewGroup) inflater.from(mContext).inflate(R.layout.lifecircle_ranking_fragment, container, false);
if (view == null) {
view = (ViewGroup) inflater.from(mContext).inflate(R.layout.lifecircle_ranking_fragment, container, false);
//輪播圖
initialize();
}
return view;
}
這樣就不會報錯了
