Question

我正在使用ViewPager，其扩展名为PagerAdapter。没有涉及Fragments。我正在使用ViewPager和常规Views。我注意到，当浏览视图时，视图不会保持端到端的连接/连接。这就像一个无限的边缘。（开始或结束情况没有问题，只有刷卡时的动态情况。）

如何在下一页中立即滑动？

要明确：我正在看

而我希望看到：

我注意到使用带有标签的操作栏和FragmentPagerAdapter，然后使用ViewPager和Fragments，确实有这种正确的行为。虽然它有时也会留下空白。

这是我的代码：

Answer 1

这是如何使用布局实现ViewPager：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    MyPagerAdapter adapter = new MyPagerAdapter();
    ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
    myPager.setAdapter(adapter);
    myPager.setCurrentItem(2);
}

将PagerAdapter定义为：

private class MyPagerAdapter extends PagerAdapter {
        public int getCount() {
            return 5;
        }
        public Object instantiateItem(View collection, int position) {
            LayoutInflater inflater = (LayoutInflater) collection.getContext()
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            int resId = 0;
            switch (position) {
            case 0:
                resId = R.layout.farleft;
                break;
            case 1:
                resId = R.layout.left;
                break;
            case 2:
                resId = R.layout.middle;
                break;
            case 3:
                resId = R.layout.right;
                break;
            case 4:
                resId = R.layout.farright;
                break;
            }
            View view = inflater.inflate(resId, null);
            ((ViewPager) collection).addView(view, 0);
            return view;
        }
        @Override
        public void destroyItem(View arg0, int arg1, Object arg2) {
            ((ViewPager) arg0).removeView((View) arg2);
        }
        @Override
        public boolean isViewFromObject(View arg0, Object arg1) {
            return arg0 == ((View) arg1);
        }
        @Override
        public Parcelable saveState() {
            return null;
        }
}

当我忘记我的心灵感应头盔，并且无法阅读你的代码时，那里一定有些错误！

从这个简单的例子开始，尝试找出实施中的错误。

Answer 2

问题是我在instantiateItem()重新审视了观点。我的猜测是我在错误的时刻从父母那里删除它们，因此白色无限边缘（没有下一个视图）。我需要将TextViews作为ViewPager的子项进行静态定义，将其从FrameLayout中移除，但留在虚拟TextView中。然后不再需要从父项中删除。

这是我的固定代码：

请注意，此代码可以进一步美化，并且可能包含一些小的过量。另外，最后，我没有使用静态视图，而是整合了Waza_Be的布局膨胀概念，因为它更接近Fragments而实际上没有Fragments，并且分离长布局似乎是好主意。功能与之相同。
