Java 如何从另一个活动的片段中单击按钮打开另一个活动中包含WebView的片段？

我在一个活动的某个片段中有图像按钮，并希望在另一个活动中单击按钮时打开包含网络视图的相应片段。 我是一个初学者，所以请给这个适当的代码

活动\u main.xml

这些是我想要的文件，如果我点击about\u img\u btn，那么它应该在另一个活动中打开一个包含webView的片段。所有按钮都应重复此操作。 请定义我必须使用的进一步代码，并提及我必须使用它的文件。谢谢

试试这个：

在

fragment\u lower\u main

xml中：

为Framelayout指定一个id：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.administrator.hiha.Lower_main_Fragment">
    <FrameLayout
         android:id="+@id/fragment_container"
         android:layout_width="match_parent"
         android:layout_height="match_parent">

         <--Rest of the code -->
    />
</LinearLayout>

---

使用

FragmentTransaction

，@Piyus我是初学者，请您定义应该在哪里使用哪些代码？检查是否需要nestead Fragments因为您说您必须为web vew打开新活动，那么为什么在另一个活动中使用fragment for webview？

  about_img_btn=(ImageButton)rootView.findViewById(R.id.about_img_btn);

 about_img_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AboutUS fragment = new AboutUS();
                Replace_fragment(fragment); //pass the fragment u want to replace
            }
        });


 public void ReplaceFragment(Fragment r_fragment) {
    FragmentManager fragmentManager = getActivity.getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.fragment_container, r_fragment).commit();
}
