Я застрял здесь в течение 3 часов не могу сделать anyhting о моих изображениях не отображаются в режиме Landsacpe в таблетках, но в моем телефоне его показ, но его strectched Вот мой код изображения

package com.example.jcw; 
import android.content.Context; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.RelativeLayout; 

public class ViewPagerAdapter extends PagerAdapter { 
    // Declare Variables 
    Context context; 
    int[] flag; 
    String[] rank; 
    LayoutInflater inflater; 

    public ViewPagerAdapter(Context context, int[] flag, String[] rank) { 
     this.context = context; 
     this.flag = flag; 
     this.rank = rank; 
    } 

    @Override 
    public int getCount() { 
     return flag.length; 
    } 

    @Override 
    public boolean isViewFromObject(View view, Object object) { 
     return view == ((RelativeLayout) object); 
    } 

    @Override 
    public Object instantiateItem(ViewGroup container, int position) { 

     ImageView imgflag; 

     inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View itemView = inflater.inflate(R.layout.app3x, container, 
       false); 



     // Locate the ImageView in viewpager_item.xml 
     imgflag = (ImageView) itemView.findViewById(R.id.flag); 

     // Capture position and set to the ImageView 
     imgflag.setImageResource(flag[position]); 

     // Add viewpager_item.xml to ViewPager 
     ((ViewPager) container).addView(itemView); 

     return itemView; 
    } 

    @Override 
    public void destroyItem(ViewGroup container, int position, Object object) { 
     // Remove viewpager_item.xml from ViewPager 
     ((ViewPager) container).removeView((RelativeLayout) object); 

    } 
} 

layout.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:gravity="center" 
android:orientation="horizontal" 
android:background="@color/White" 

> 

<ImageView 
    android:id="@+id/flag" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_alignParentRight="true" 
    android:background="@color/White" 
    android:scaleType="fitXY" /> 

Это где я использовать адаптер

package com.example.jcw; 


import android.os.Bundle; 
import android.app.Activity; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.view.Window; 
import android.view.WindowManager; 

import com.viewpagerindicator.UnderlinePageIndicator; 

public class activity3 extends Activity 
{ 


    ViewPager viewPager; 
    PagerAdapter adapter; 
    int[] flag; 
    String[] rank; 
    UnderlinePageIndicator mIndicator; 




    @Override public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
            WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    setContentView(R.layout.app3); 


     rank = new String[] { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14" , "15" ,"16" , "17" , "18" }; 


     flag = new int[] { R.drawable.gr, R.drawable.calvitc, 
       R.drawable.barleyjuice, R.drawable.hilifejuice, R.drawable.calvitc2guys, R.drawable.calvitcteddy, 
       R.drawable.kapesupremo, R.drawable.glutafit, R.drawable.omniwhitelotion, R.drawable.omniwhitebbcream , 
       R.drawable.omniwhitepinkishcream , R.drawable.omniwhitesoap, R.drawable.omniwhitetoner, 
       R.drawable.organicbarley, R.drawable.premieregreentea, R.drawable.shuya, R.drawable.omniwhitecream, 
       R.drawable.organicspirulina }; 

    // Locate the ViewPager in viewpager_main.xml 
    viewPager = (ViewPager) findViewById(R.id.pager); 
    // Pass results to ViewPagerAdapter Class 
    adapter = new ViewPagerAdapter(activity3.this, flag , rank); 
    // Binds the Adapter to the ViewPager 
    viewPager.setAdapter(adapter); 

    // ViewPager Indicator 
    mIndicator = (UnderlinePageIndicator) findViewById(R.id.indicator); 
    mIndicator.setFades(false); 
    mIndicator.setViewPager(viewPager); 




    }
