View Pager In Android

Hi Guys!


Today I am going to share the code to make a view pager in android. In the new API- 17 gallery is debricated  now. So android developer suggest that please use the view pager or horizontal scroll veiw in place of Gallery.

Viewpager  is  the best way to switching among view. It provide a way to swipe views from left to right and right to left. Viewpager provide strong way to swipe any views but here i have taken ImageView to swipe left and right.
Here the the link, you can see the ViewPager in android API.

Add the support library while you are creating project because Viewpager does not support in lower android version.

miain.xml

PageIndicatorActivity.java

package com.sunil.viewpager;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.view.Menu;

public class PageIndicatorActivity extends Activity {

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  ViewPagerAdapter adapter = new ViewPagerAdapter(this, imageArra);
  ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
  myPager.setAdapter(adapter);
  myPager.setCurrentItem(0);
 }

 private int imageArra[] = { R.drawable.sunn, R.drawable.sunnew,
   R.drawable.sunn, R.drawable.sunnew,
   R.drawable.sunn, R.drawable.sunnew,
   R.drawable.sunn, R.drawable.sunnew, };


}

ViewPagerAdapter.java

package com.sunil.viewpager;

import android.app.Activity;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class ViewPagerAdapter extends PagerAdapter {

 Activity activity;
 int imageArray[];

 public ViewPagerAdapter(Activity act, int[] imgArra) {
  imageArray = imgArra;
  activity = act;
 }

 public int getCount() {
  return imageArray.length;
 }

 public Object instantiateItem(View collection, int position) {
   ImageView view = new ImageView(activity);
   view.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
   view.setScaleType(ScaleType.FIT_XY);
   view.setBackgroundResource(imageArray[position]);
   ((ViewPager) collection).addView(view, 0);
  return view;
 }

 @Override
 public void destroyItem(View arg0, int arg1, Object arg2) {
    ((ViewPager) arg0).removeView((View) arg2);
 }

 @Override
 public boolean isViewFromObject(View arg0, Object arg1) {
  return arg0 == ((View) arg1);
 }

 @Override
 public Parcelable saveState() {
  return null;
 }
}

 

Cheers Guys!
