可滑动的线性/相对布局

Question

I am relatively a beginner in android. I was trying to build a similar app as the calculator shown below. The problem that I am facing is regarding deciding how to swipe the scientific part of the calculator to the right as shown in the image. It is certainly not a ViewPager , or is it? I cannot conclude how to build this feature. Shall I use a RelativeLayout and use my own java code to make it swipable. If so then how? Please help me regarding ?

Answer 1

If you do not want to use ViewPager , you can use ViewFlipper .

You can use ViewPager . You should create two fragments, for example BasicButtonsFragment and ScientificButtonsFragment . Then you should create a FragmentPagerAdapter .

public static class MyAdapter extends FragmentPagerAdapter {
    public MyAdapter(FragmentManager fm) {
        super(fm);
    }

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

    @Override
    public Fragment getItem(int position) {
        if (position == 0)
            return BasicButtonsFragment.newInstace();
        return ScientificButtonsFragment.newInstance();
    }
}

Finnaly, set this adapter to your ViewPager .

You can you a DrawerLayout. Check it on the google. I think that is what you are looking for.
