禁用在fragmentPagerAdapter中滑动? - 安卓 [英] Disable swipe in fragmentPagerAdapter? - android

问题描述

大家好，我有一个带有3个片段的fragmentPagerAdapter.我将如何禁用3个片段之间的滑动，使用户仅使用tabview在片段之间移动?

Hey guys i have a fragmentPagerAdapter with 3 fragments in it. How would i disable the swiping between the 3 fragments so the user only uses the tabview to go between fragments?

干杯！

private class ViewPagerAdapter extends FragmentPagerAdapter
{
    ArrayList<Fragment> fragments = new ArrayList<>();
    ArrayList<String> tabTitles = new ArrayList<>();

    public ViewPagerAdapter(android.support.v4.app.FragmentManager fragmentManager)
    {
        super(fragmentManager);
    }
    @Override
    public Fragment getItem(int position)
    {
        return fragments.get(position);
    }
    @Override
    public int getCount()
    {
        return fragments.size();
    }
    @Override
    public CharSequence getPageTitle(int position)
    {
        return tabTitles.get(position);
    }
    public void addFragments(Fragment fragment, String titles)
    {
        this.fragments.add(fragment);
        this.tabTitles.add(titles);
    }
}

推荐答案

您可以像这样设置自定义视图分页器:-

You can setup a custom view pager like this :-

public class LockableViewPager extends ViewPager {
    private boolean swipeable;

    public LockableViewPager(Context context) {
        super(context);    
    }    

    public LockableViewPager(Context context, AttributeSet attrs) {    
        super(context, attrs);    
        this.swipeable = true;    
    }

    @Override    
    public boolean onTouchEvent(MotionEvent event) {    
        if (this.swipeable) {    
            return super.onTouchEvent(event);    
        }    
        return false;    
    }

    @Override

    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.swipeable) {
            return super.onInterceptTouchEvent(event);
        }
        return false;
    }

    public void setSwipeable(boolean swipeable) {
        this.swipeable = swipeable;
    }
}

然后在布局中可以将其设置为:-

And then in the layout you can set it as :-

<mypackage.lockableviewpager 
    android:id="@+id/photosViewPager" 
    android:layout_height="match_parent"
    android:layout_width="match_parent"/>

然后致电

setSwipeable(false)
