Question

我已经尝试解决这个问题 5 天了，但仍然没有解决。

主要Java代码

当我单击抽屉导航中的“主页”菜单项时，它工作正常。但是当我再次单击“主页”后，我收到此异常

02-16 20:08:05.714: E/AndroidRuntime(5999): android.view.InflateException: Binary XML file line #8: Error inflating class fragment 

java代码有修改吗？请帮我解决这个问题。
谢谢

Answer 1

将以下变量添加到 Fragment 类中:

private static View view;

然后在同一个 fragment 类中尝试替换 onCreateView 方法:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
if(view != null)
    {
        ViewGroup parent = (ViewGroup) view.getParent();
        if(parent != null)
        {
            parent.removeView(view);
        }
    }
    try
    {
        view = inflater.inflate(R.layout.fragment_places, container, false);
    }
    catch(InflateException e){
        // map is already there, just return view as it is
    }
    return view;

}
