ViewPager禁用刷到一定方向 [英] ViewPager disable swiping to a certain direction

问题描述

我要禁用刷卡，但只有右侧。我发现这的答案。遗憾的是，这份全 ViewPager 源要达到的目标。有刚继承现有类，而不是复制的任何方法？

I want to disable the swiping, but only to the right side. I found a working solution in this answer. Unfortunately, this copies the whole ViewPager source to achieve the goal. Is there any methods just inheriting the existing class and not duplicating?

推荐答案

我不知道这正是你需要： 我需要一个viewpager为与最大页面向导，用户无法通过。

I'm not sure this is exactly what you need: I needed a viewpager for a wizard with a max page that the user can't pass it.

目前终了时，溶液是在适配器。 我改变了PagerAdapter的数量，这种方式阻止用户从通过最大页面：

At the end the solution was in the adapter. I changed the count of the PagerAdapter and this way blocks the user from passing the max page:

@Override
public int getCount() {
    return mProgress; //max page + 1
}

当用户前进到下一个页面：

When the user progresses to the next page:

private void setWizardProgress(int progress) {
    if(progress > mProgress) {
        mProgress = progress;
        mWizardPagerAdapter.notifyDataSetChanged();
    }
}

这样当用户在最大页，他不能滚动到右侧。

This way when the user is at max page he can't scroll to the right.
