首先是主代码块

package alice.bw.com.day01zhoukao;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Gravity;
import android.view.Menu;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

import java.util.ArrayList;

import alice.bw.com.day01zhoukao.adapter.MyViewpgerAdaper;
import alice.bw.com.day01zhoukao.fragment.A_Fragmen;
import alice.bw.com.day01zhoukao.fragment.B_Fragment;
import alice.bw.com.day01zhoukao.fragment.C_Fragment;

public class MainActivity extends AppCompatActivity implements RadioGroup.OnCheckedChangeListener {
    private Toolbar mToolbar;
    private DrawerLayout mDrawerLayout;
    private TextView drawer_layout_tv;
    private ViewPager vp;
    private ArrayList<Fragment> mFragments;
    private RadioGroup rg;
    private RadioButton[] rbArray ;
    private MyViewpgerAdaper mAdaprer;
    private FragmentManager fm ;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }

    private void initView() {
        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        mFragments.add(new C_Fragment());
        fm = getSupportFragmentManager();
        mAdaprer = new MyViewpgerAdaper(fm,mFragments);
        vp.setAdapter(mAdaprer);
        vp.setCurrentItem(0);

        mToolbar.setNavigationIcon(R.mipmap.ic_launcher);
        mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mDrawerLayout.openDrawer(Gravity.LEFT);
            }
        });
        drawer_layout_tv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                vp.setCurrentItem(1);
            }
        });
        rg = (RadioGroup) findViewById(R.id.rg);
        rbArray = new RadioButton[rg.getChildCount()];
        for (int i = 0; i <rbArray.length ; i++) {
            rbArray[i] = (RadioButton) rg.getChildAt(i);
        }
        rbArray[0].setChecked(true);
        rg.setOnCheckedChangeListener(this);
        vp.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                for (int i = 0; i <rbArray.length ; i++) {
                    if(position == i){
                        vp.setCurrentItem(i);
                        rbArray[i].setChecked(true);
                    }
                }

            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main,menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public void onCheckedChanged(RadioGroup radioGroup, int id) {
        for (int i = 0; i <rbArray.length ; i++) {
            if(id == rbArray[i].getId()){
                vp.setCurrentItem(i);
            }
        }
    }
}

        }
        LinearLayoutManager manager = new LinearLayoutManager(getActivity());
