Android ViewPager实现左右滑动的实例
AndroidViewPager实现左右滑动的实例
多个标题以及标题下的每个View视图
在build.gradle添加包：
//左右滑动布局框架 compile'com.shizhefei:ViewPagerIndicator:1.1.4'
然后在代码中实现功能：
ScrollIndicatorViewscrollIndicatorView;
ViewPagerviewPager;
privateString[]titles={"在线申办","信用卡代换","信用卡取现","办卡进度"};
privateIndicatorViewPagerindicatorViewPager;
privateLayoutInflaterinflate;
privateContextmContext;
privatevoidinitViewPager(){
//默认字体是14
floatunSelectSize=14;
//滑动字体是14*1.2f
floatselectSize=unSelectSize;
scrollIndicatorView.setOnTransitionListener(newOnTransitionTextListener().setColor(0xFF1DA9FF,Color.GRAY).setSize(selectSize,unSelectSize));
scrollIndicatorView.setScrollBar(newColorBar(mContext,0xFF1DA9FF,2));
viewPager.setOffscreenPageLimit(1);
indicatorViewPager=newIndicatorViewPager(scrollIndicatorView,viewPager);
inflate=LayoutInflater.from(mContext);
indicatorViewPager.setAdapter(newMyAdapter(getFragmentManager()));
}
privateintsize=titles.length;
privateclassMyAdapterextendsIndicatorViewPager.IndicatorFragmentPagerAdapter{
publicMyAdapter(FragmentManagerfragmentManager){
super(fragmentManager);
}
@Override
publicintgetCount(){
returnsize;
}
@Override
publicViewgetViewForTab(intposition,ViewconvertView,ViewGroupcontainer){
if(convertView==null){
convertView=inflate.inflate(R.layout.tab_top,container,false);
}
TextViewtextView=(TextView)convertView;
textView.setText(titles[position%titles.length]);
intpadding=dipToPix(10);
textView.setPadding(padding,0,padding,0);
returnconvertView;
}
@Override
publicFragmentgetFragmentForPage(intposition){
CreditCardFragmentfragment=newCreditCardFragment();
/*Bundlebundle=newBundle();
bundle.putInt(MoreFragment.INTENT_INT_INDEX,position);
fragment.setArguments(bundle);*/
returnfragment;
//MoreFragmentfragment=newMoreFragment();
//Bundlebundle=newBundle();
//bundle.putInt(MoreFragment.INTENT_INT_INDEX,position);
//fragment.setArguments(bundle);
//returnfragment;
}
@Override
publicintgetItemPosition(Objectobject){
//这是ViewPager适配器的特点,有两个值POSITION_NONE，POSITION_UNCHANGED，默认就是POSITION_UNCHANGED,
//表示数据没变化不用更新.notifyDataChange的时候重新调用getViewForPage
returnPagerAdapter.POSITION_NONE;
}
}
privateintdipToPix(floatdip){
intsize=(int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,dip,getResources().getDisplayMetrics());
returnsize;
}
