Java 查看寻呼机中的按钮

我试图在PageView片段中添加按钮

请参阅附件中我用于此应用程序的代码：

xml的特定代码为：

<?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"
    android:orientation="vertical">
    <LinearLayout 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
            <Button
            android:id="@+id/banner_name"
            android:layout_width="fill_parent"
            android:layout_height="30dp"
            android:background="@drawable/button_banner"
            android:gravity="center_vertical"
            android:paddingLeft="10dip"
            android:text="@string/equations"
            android:textStyle="bold"
            android:textColor="#ffffff" />
    </LinearLayout>
    <ScrollView 
        android:id="@+id/ScrollViewEquations"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <LinearLayout 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
            <Button
                android:id="@+id/Button"
                android:layout_width="fill_parent"
                android:layout_height="25dip"
                android:background="@drawable/custom_button"
                android:gravity="center_vertical"
                        android:paddingLeft="25dip"
                android:textColor="#516CE2"
                android:text="@string/button" />
        </LinearLayout>
    </ScrollView>
</LinearLayout

这是主要代码：

package com.example.app;

import com.example.app.R;
import com.google.ads.AdRequest;
import com.google.ads.AdView;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.Window;
import android.view.WindowManager;

public class Main extends FragmentActivity {
    private MyAdapter mAdapter;
    private ViewPager mPager;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
        mAdapter = new MyAdapter(getSupportFragmentManager());

        AdView adView = (AdView)this.findViewById(R.id.adView);
        adView.loadAd(new AdRequest()); 

        mPager = (ViewPager) findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);
    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return 3;
        }

        @Override
        public Fragment getItem(int position) {
            switch (position) {
            case 0:
                return new EquationsMain();
            case 1:
                return new MaterialsMain();
            case 2:
                return new AboutMain();
            default:
                return null;
            }
        }
    }
}

我想在其中一个片段中添加一个按钮，打开一个新页面是的，我知道了，但问题出在哪里？=）我对android很陌生，我不知道在类filespublic class Main extends活动实现OnClickListener{@Override public void onCreate（Bundle savedInstanceState）{super.onCreate（savedInstanceState）；requestWindowFeature（Window.FEATURE_NO_TITLE）；setContentView（R.layout.Main）；View equationsButton=findViewById（R.id.equations_按钮）；equationsButton.setOnClickListener（this）；}public void onClick（View v）{switch（v.getId（））{case R.id.equations_按钮：Intent i=新Intent（this，equations.class）；startActivity（i）；}}

package com.example.app;

import android.support.v4.view.ViewPager;
import android.view.Window;
import android.view.WindowManager;

public class Main extends FragmentActivity {
    private MyAdapter mAdapter;
    private ViewPager mPager;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
        mAdapter = new MyAdapter(getSupportFragmentManager());

        AdView adView = (AdView)this.findViewById(R.id.adView);
        adView.loadAd(new AdRequest()); 

        mPager = (ViewPager) findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);
    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return 3;
        }

        @Override
        public Fragment getItem(int position) {
            switch (position) {
