Android ViewPager instance Code 2.

I have previously written a ViewPager: content + indicator Demo;

This article continues to introduce ViewPager: content + title Demo.

Implementation:

Source code:

Layout file: activity_main:

F1.xml (Sports News layout file ):

F2.xml (Entertainment News layout file ):

F3.xml (Military News layout file ):

Code file:

MainActivity:

Package com. fragmentdemo11_viewpager; import java. util. arrayList; import java. util. list; import android. app. activity; import android. OS. bundle; import android. support. v4.view. viewPager; import android. view. layoutInflater; import android. view. view; public class MainActivity extends Activity {private ViewPager viewPager; private List
 
  
Title; private List
  
   
Content; private LayoutInflater inflater; private MyViewPagerAdapter adapter; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); viewPager = (ViewPager) findViewById (R. id. viewPager); content = new ArrayList
   
    
(); Inflater = LayoutInflater. from (this);/*** add content */content. add (inflater. inflate (R. layout. f1, null); content. add (inflater. inflate (R. layout. f2, null); content. add (inflater. inflate (R. layout. f3, null);/*** Add the title corresponding to each content */title = new ArrayList
    
     
(); Title. add ("Sports News"); title. add ("Entertainment News"); title. add ("Military News"); adapter = new MyViewPagerAdapter (this, content, title); viewPager. setAdapter (adapter );}}
    
   
  
 

ViewPager adapter:

Package com. fragmentdemo11_viewpager; import java. util. list; import android. content. context; import android. support. v4.view. pagerAdapter; import android. support. v4.view. viewPager; import android. view. view; import android. view. viewGroup;/*** ViewPager adapter */public class MyViewPagerAdapter extends PagerAdapter {private Context context; private List
  
   
Content; private List
   
    
Title; public MyViewPagerAdapter (Context context, List
    
     
Content, List
     
      
Title) {this. context = context; this. content = content; this. title = title;}/*** initialization */@ Overridepublic Object instantiateItem (ViewGroup container, int position) {(ViewPager) container ). addView (content. get (position); return content. get (position);}/*** title */@ Overridepublic CharSequence getPageTitle (int position) {return title. get (position) ;}@ Overridepublic int getCount () {return content. size () ;}@ Overridepublic boolean isViewFromObject (View arg0, Object arg1) {return arg0 = arg1 ;}/ *** destroy */@ Overridepublic void destroyItem (ViewGroup container, int position, Object object) {(ViewPager) container ). removeView (content. get (position ));}}
