如何在另一个活动上打开包含webViews的片段按钮单击其他活动的片段？

我在一个活动的片段之一中有图像按钮，并希望在另一个活动的按钮点击中打开包含webViews的相应片段。我是初学者，所以请给与适当的代码。如何在另一个活动上打开包含webViews的片段按钮单击其他活动的片段？

activity_main.xml中

Lower_Main_Fragment.java

package com.example.administrator.hiha; 

import android.content.Context; 
import android.net.Uri; 
import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageButton; 

public class Lower_main_Fragment extends Fragment { 

    ImageButton about_img_btn; 
    ImageButton sarasvati_img_btn; 
    ImageButton scientific_evidences_img_btn; 
    ImageButton digital_library_img_btn; 
    ImageButton affltd_oragnization_img_btn; 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View rootView=inflater.inflate(R.layout.fragment_lower_main_,container,false); 

     //cast image buttons 
     about_img_btn=(ImageButton)getView().findViewById(R.id.about_img_btn); 
     sarasvati_img_btn=(ImageButton)getView().findViewById(R.id.sarasvati_img_btn); 
     scientific_evidences_img_btn=(ImageButton)getView().findViewById(R.id.scientific_evidences_img_btn); 
     digital_library_img_btn=(ImageButton)getView().findViewById(R.id.digital_library_img_btn); 
     affltd_oragnization_img_btn=(ImageButton)getView().findViewById(R.id.affltd_oragnization_img_btn); 

     return rootView; 

    } 

    //onclick methods of image buttons 
    public void onAboutBoardClick(View view){ 

    } 
}

这些都是在我想，如果我点击about_img_btn那么它应该打开包含在另一活动网页视图片段的文件。对于所有按钮应该重复相同的操作。请定义我必须使用的进一步代码，并提及必须使用它的文件。谢谢！使用单击按钮时

<?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="[email protected]/fragment_container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

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

现在在代码开放的新片段：

使用'FragmentTransaction'， – Piyush

@Piyush我是一个初学者所以，你可以定义哪些代码应该用在哪里？ –

检查[this]（http://stackoverflow.com/questions/23212162/how-to-move-from-one-fragment-to-another-fragment-on-click-of-a-imageview-in-and） – Piyush

试试这个：

在 fragment_lower_main XML

：

给一个ID，FrameLayout里

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(); 
}
