Question

当我单击ImageView时，应用程序崩溃。

在单击“图像视图”后尝试导航至具有卡视图的片段。也有片段重影问题，但该代码现在已注释。我也尝试修复此问题，但未成功。

这是我的代码：

mainroute.java：

 wiButton.setOnClickListener(new View.OnClickListener() {
            @Override
            //@SuppressWarnings("ResourceType")
            public void onClick(View v) {

                FragmentManager mFragmentManager = getActivity().getSupportFragmentManager();//.findFragmentByTag("WifiFragment");

                /*if (mFragment == null) {
                    // wifiFragment = WifiFragment.newInstance();
                    mFragmentTransaction.add(R.id.WifiLayout, wifiFragment, "WifiFragment");
                } else {
                    wifiFragment = (WifiFragment) mFragment;*/

                    FragmentTransaction mFragmentTransaction = mFragmentManager.beginTransaction();
                    WifiFragment wifiFragment = new WifiFragment();
                    mFragmentTransaction.add(R.id.WifiLayout, wifiFragment);
                    mFragmentTransaction.commit();
                    fICardView.setVisibility(View.VISIBLE); 
                }

            });

logcat是：

2019-02-15 21:32:09.777 1814-1827/? E/memtrack: Couldn't load memtrack module

我曾尝试过这篇文章：Android Fragment no view found for ID?

我试图找到我的r.java文件，我找到了我的wifilayout ID： r.java：

public static final int WifiLayout=0x7f07002f;

此片段的另一个函数中发生了相同的问题。

我试图getChildFragmentManager()：

noButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FragmentManager mFragmentManager = getChildFragmentManager();
                FragmentTransaction mFragmentTransaction = mFragmentManager.beginTransaction();
                NoteFragment noteFragment = new NoteFragment();
                mFragmentTransaction.add(R.id.NoteLayout, noteFragment);
                mFragmentTransaction.commit();
                fICardView.setVisibility(View.VISIBLE);
            }

        });

非常感谢。

Answer 1

如果布局文件WifiLayout位于布局文件夹中，则必须使用R.layout.WifiLayout而不是R.id.WifiLayout。

所有布局文件都一样。

最佳
