To customize the left and right swipe effect of an Android application, you can use ViewPager and Fragment to achieve this. Here are some steps:

  1. First, define a ViewPager component in the XML layout file. For example:
<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
  1. Create a custom FragmentPagerAdapter to manage the pages of a ViewPager. For example:
public class MyPagerAdapter extends FragmentPagerAdapter {
    private List<Fragment> fragments;

    public MyPagerAdapter(FragmentManager fm, List<Fragment> fragments) {
        super(fm);
        this.fragments = fragments;
    }

    @Override
    public Fragment getItem(int position) {
        return fragments.get(position);
    }

    @Override
    public int getCount() {
        return fragments.size();
    }
}
  1. Initialize the ViewPager and FragmentPagerAdapter in the Activity, and set the adapter for the ViewPager. For example:
ViewPager viewPager = findViewById(R.id.viewPager);
List<Fragment> fragments = new ArrayList<>();
fragments.add(new Fragment1());
fragments.add(new Fragment2());
fragments.add(new Fragment3());
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(adapter);
  1. Customize the layout and logic of each Fragment. For example, define a TextView in Fragment1.
public class Fragment1 extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment1, container, false);
        TextView textView = view.findViewById(R.id.textView);
        textView.setText("Fragment 1");
        return view;
    }
}
  1. You can add animation effects to page transitions in the ViewPager. For example, you can customize page transition animations with ViewPager.PageTransformer.
public class MyPageTransformer implements ViewPager.PageTransformer {
    @Override
    public void transformPage(@NonNull View view, float position) {
        // 自定义页面切换动画逻辑
    }
}

Set a custom PageTransformer to the ViewPager.

viewPager.setPageTransformer(true, new MyPageTransformer());

By following the steps above, you can achieve a customized left and right swipe effect. Depending on your needs, you can further modify the code to achieve the desired effect.
