Android Fragment+Viewpager实现左右滑动和点击 实现DrawerLayout

xml布局代码:

<android.support.v4.widget.DrawerLayout xmlns:android=“http://schemas.android.com/apk/res/android”

java代码:

public class MainActivity extends AppCompatActivity {

private ViewPager pager;
private RadioGroup radioGroup;
private ArrayList<Fragment> list;
private DrawerLayout drawerLayout;
private ActionBar actionBar;
private ActionBarDrawerToggle toggle;

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

    //找控件
    pager = (ViewPager) findViewById(R.id.viewPager);
    radioGroup = (RadioGroup) findViewById(R.id.radioGroup);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);

    initAction();
    
    //默认选中第一个页面
    radioGroup.check(radioGroup.getChildAt(0).getId());

    //创建集合
    list = new ArrayList<>();
    list.add(new Frag01());
    list.add(new Frag02());
    list.add(new Frag03());
    list.add(new Frag04());
    list.add(new Frag05());

    //适配器
    pager.setAdapter(new PagerAdapter(getSupportFragmentManager(), list));

    pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int i, float v, int i1) {

        }

        @Override
        public void onPageSelected(int i) {
            radioGroup.check(radioGroup.getChildAt(i).getId());
        }

        @Override
        public void onPageScrollStateChanged(int i) {

        }
    });

    //联动
    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
             pager.setCurrentItem(checkedId - 1);
           /* switch (checkedId) {
                case R.id.button1:
                    pager.setCurrentItem(0);
                    break;
                case R.id.button2:
                    pager.setCurrentItem(1);
                    break;
                case R.id.button3:
                    pager.setCurrentItem(2);
                    break;
                case R.id.button4:
                    pager.setCurrentItem(3);
                    break;
                case R.id.button5:
                    pager.setCurrentItem(4);
                    break;*/
            }
        }
    });
}

private void initAction() {

    actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
    toggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.open, R.string.close);
    toggle.syncState();
    drawerLayout.addDrawerListener(toggle);

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (toggle.onOptionsItemSelected(item)){
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

新建一个Class,侧拉页面:
public class FragmentNav extends Fragment {

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment,container,false);
    return view;
}

}
