CustomPagerAdapter:

 public class CustomPagerAdapter extends PagerAdapter { public Object instantiateItem(View collection, int position) { LayoutInflaterinflater = (LayoutInflater) collection.getContext() .getSystemService(Context.LAYOUT_INFLatER_SERVICE); int resId = 0; switch (position) { case 0: { resId = R.layout.lab; break; } case 1: { resId = R.layout.lab; break; } case 2: { resId = R.layout.etela; break; } case 3: { resId = R.layout.ticket; break; } case 4: { resId = R.layout.product; break; } case 5: { resId = R.layout.about; break; } } View view = inflater.inflate(resId, null); ((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 saveSt ate() { return null; } @Override public int getCount() { return 6; } 

Mi actividad:

 public class MyActivity extends Activity { ViewPager myPager = null; ImageButton contact = null; ImageButton about = null; ImageButton lab = null; ImageButton product = null; ImageButton ticket = null; ImageButton etela = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); CustomPagerAdapter adapter = new CustomPagerAdapter(); myPager = (ViewPager) findViewById(R.id.customviewpager); myPager.setAdapter(adapter); myPager.setCurrentItem(5); myPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { public void onPageScrolled(int i, flo at v, int i2) { } public void onPageSelected(int i) { } public void onPageScrollStateChanged(int i) { Thread t1 = new Thread(new Runnable() { @Override public void run() { switch (myPager.getCurrentItem()) { case 0: break; case 1: break; case 2: break; case 3: break; case 4: break; case 5: break; } } }); t1.start(); } }); } 

Y es el diseño de laboratorio:

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/lab1"/> </LinearLayout> 

El uso de imágenes grandes podría causar este error. Es muy recomendable reducir los tamaños de las imágenes y luego cargarlas en ImageViews.

También hay otra manera de solicitar android para darle a tu aplicación más memoria añadiendo lo siguiente al manifiesto. Pero esto no es recomendable. Para más información, mira aquí y aquí .
