ViewPager不响应在Fragment中动态创建的布局区域中的触摸 [英] ViewPager not responding to touch in layout area created dynamically in Fragment
本文介绍了ViewPager不响应在Fragment中动态创建的布局区域中的触摸的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用日历实现Viewpager.我正在使用日历Fragment的相同三个实例来测试ViewPager，让我们调用将一个片段传输到下一个SWIPING的平滑动作.滑动不会在片段本身中动态创建布局的片段区域中起作用，但是页面的其余部分(日期按钮的上方和下方)滑动效果很好！这是整个片段代码不适合的一些代码，因此必须编辑一些声明和按钮侦听器方法
I'm trying to implement Viewpager with a calendar. I'm using the same three instances of the calendar Fragment for testing the ViewPager lets call the smooth motion of transferring one fragment to the next SWIPING. the swiping will not work in the area of the fragment that the layout was created dynamically in the fragment itself but the rest of page(above and below the date buttons)the swiping works great! here is some of the code the entire frag code would not fit so had to edit some declarations and button listener methods
//主要活动
public class calenderview extends AppCompatActivity {
ArrayList<Fragment> fraglist;
ViewPager pager;
calenderviewpageradaptor adaptor;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calenderview);
fraglist = new ArrayList<>();
fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag());
adaptor = new calenderviewpageradaptor(getSupportFragmentManager(),fraglist);
pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(adaptor);
}
public class calenderviewpageradaptor extends FragmentStatePagerAdapter {
ArrayList<Fragment> adaptorlist;
public calenderviewpageradaptor(FragmentManager fm,ArrayList<Fragment> list){
super (fm);
this.adaptorlist = list;
}
@Override
public int getCount(){
return 3;
}
@Override
public Fragment getItem(int pos){
return adaptorlist.get(pos);
}
}
}

推荐答案
您要将Fragment的实例传递给适配器吗?不，我想.您应该将片段列表与片段管理器一起传递给适配器，还应该相应地更改calendarViewPager.
are you passing the instance of the Fragment to the adapter? No I think. You should pass the list of fragments to the adapter along with fragment manager and should also change the calendarViewPager accordingly.
List<Fragment> fragments =new ArrayList<>();
fragments.add(Calview_frag());
fragments.add(Calview_frag());
fragments.add(Calview_frag());
calenderviewpageradaptor adaptor =
new calenderviewpageradaptor(getSupportFragmentManager(),fragments);
