MainActivity

viewpager+Fragment切换的功能代码

public class MainActivity extends AppCompatActivity {

private ViewPager viewPager;
private RadioGroup radioGroup;
private List<Fragment> list;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle toggle;

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

    drawerLayout=findViewById(R.id.drawer);
    viewPager=findViewById(R.id.viewPager);
    radioGroup=findViewById(R.id.group);

    list=new ArrayList<>();
    list.add(new FragmentOne());
    list.add(new FragmentTwo());
    list.add(new FragmentThree());
    list.add(new FragmentFour());

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


    viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
        @Override
        public Fragment getItem(int i) {
            return list.get(i);
        }

        @Override
        public int getCount() {
            return list.size();
        }
    });


    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            switch (checkedId){
                case R.id.but1:
                    viewPager.setCurrentItem(0);
                    break;
                case R.id.but2:
                    viewPager.setCurrentItem(1);
                    break;
                case R.id.but3:
                    viewPager.setCurrentItem(2);
                    break;
                case R.id.but4:
                    viewPager.setCurrentItem(3);
                    break;
            }
        }
    });

}

public void show(int positioin){
    viewPager.setCurrentItem(positioin);
    drawerLayout.closeDrawer(Gravity.START);
}


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

侧滑的fragment的点击事件

public class LeftFragment extends Fragment {
    private ListView listView;
    private MainAdapter adapter;


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

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    listView=view.findViewById(R.id.listView);

    adapter = new MainAdapter(getActivity());

    listView.setAdapter(adapter);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            if(position==0){
                return;
            }
            ((MainActivity)getActivity()).show(position-1);
        }
    });

}

侧滑的布局

<ListView
        android:id="@+id/listView"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        ></ListView>

侧滑的多条目加载 头像和listView

public class MainAdapter extends BaseAdapter {

private String[] data=new String[]{
        "影片","影院","会员","设置"
};
private Context context;

public MainAdapter(Context context) {
    this.context = context;
}

@Override
public int getCount() {
    return data.length+1;
}

@Override
public int getViewTypeCount() {
    return 2;
}

@Override
public int getItemViewType(int position) {
    return position==0?1:0;
}

@Override
public String getItem(int position) {
    if(position==0){
        return null;
    }
    return data[position-1];
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    if(getItemViewType(positio
