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;

    public class MainActivity extends AppCompatActivity implements RadioGroup.OnCheckedChangeListener {

            vp = (ViewPager) findViewById(R.id.vp);
            mFragments = new ArrayList<>();
            mFragments.add(new A_Fragmen());
            mFragments.add(new B_Fragment());
            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

                    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);
                }
            }
        }
    }
