  • xml文件中引用TopPreFragment 时报错
  • xml如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <fragment
        android:id="@+id/left_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.xxx.TopPreFragment" />
</LinearLayout>
  • 错误信息:
  • 问题原因:
    Activity与Fragment 传值时用到了 setArguments(Bundle bundle)
Bundle bundle = new Bundle();
bundle.putString("good_id", good_id);
TopPreFragment pre = new TopPreFragment();
pre.setArguments(bundle);

在TopPreFragment 中 getArguments() 会导致
android.view.InflateException: Binary XML file line #7: Binary XML file line #7: Error inflating class fragment

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_top_pre, null);
        initView(view);
        //问题处在getArguments()这里
        Bundle bundle = TopPreFragment.this.getArguments();
        goodsid = bundle.getString("good_id");
        return view;
    }
  • 解决方法
    传递数据时,用静态变量替换.setArguments(bundle);
