问题描述
这是6个片段之间约轻扫我的code ,,我想要做一个事件时,我从一个片段刷卡其他从互联网加载一些东西,,所以请任何帮助,我该怎么办呢? ?? ,,和我在哪里可以把code,等我想想进度对话框启动它在功能获得冠军,并在片段的开始是它适用取消它?
这是我的code:

使用ViewPager.OnPageChangeListener你的看法寻呼机的检测滑动或实现自定义视图寻呼机看到
添加此
mViewPager.setOnPageChangeListener(新OnPageChangeListener(){ @覆盖
公共无效使用onPageSelected(INT为arg0){
// TODO自动生成方法存根 //做事HERE } @覆盖
公共无效onPageScrolled(INT为arg0,ARG1浮球,诠释ARG2){

公共无效onPageScrollStateChanged(INT为arg0){
// TODO自动生成方法存根 }

fragments.add(Fragment.instantiate(this, FragmentFive.class.getName()));
fragments.add(Fragment.instantiate(this, FragmentSix.class.getName()));

// Set up the ViewPager with the sections adapter.

mViewPager.setAdapter(mSectionsPagerAdapter);
//
}

Use ViewPager.OnPageChangeListener of your view pager to detect swipe OR implement custom view pager see this
ADD THIS
mViewPager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(int arg0) {
// TODO Auto-generated method stub
//DO THINGS HERE
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
