Android Image SliderAndroid image slider slides one entire screen to another screen. Image slider is created by ViewPager which is provided by support library. To implement image slider, you need to inherit ViewPager class which extends PagerAdapter. Example of Image SliderLet's see an example of android image slider. activity_main.xmlIn activity_main.xml file, we have wrapped ViewPager inside RelativeLayout. File: activity_main.xml <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.test.imageslider.MainActivity"> <android.support.v4.view.ViewPager android:id="@+id/viewPage" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </RelativeLayout> Activity classFile: MainActivity.java package com.example.test.imageslider; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewPager mViewPager = (ViewPager) findViewById(R.id.viewPage); ImageAdapter adapterView = new ImageAdapter(this); mViewPager.setAdapter(adapterView); } } ImageAdapter classNow create ImageAdapter class which extends PagerAdapter for android image slider. Place some images in drawable folder which are to be slid. File: ImageAdapter.java package com.example.test.imageslider; import android.content.Context; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; public class ImageAdapter extends PagerAdapter{ Context mContext; ImageAdapter(Context context) { this.mContext = context; } @Override public boolean isViewFromObject(View view, Object object) { return view == ((ImageView) object); } private int[] sliderImageId = new int[]{ R.drawable.image1, R.drawable.image2, R.drawable.image3,R.drawable.image4, R.drawable.image5, }; @Override public Object instantiateItem(ViewGroup container, int position) { ImageView imageView = new ImageView(mContext); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setImageResource(sliderImageId[position]); ((ViewPager) container).addView(imageView, 0); return imageView; } @Override public void destroyItem(ViewGroup container, int position, Object object) { ((ViewPager) container).removeView((ImageView) object); } @Override public int getCount() { return sliderImageId.length; } } We need to override following methods of PagerAdapter class.
