I implemented in my app an activity that uses a ViewPager, with a PagerAdapter to show 4 images. You can see only one image at time and to show the next you have to swipe it. The size of the images is not very huge and I don't know why but it happens the error "java.lang.OutOfMemoryError bitmap size exceeds VM budget pageradapter".
This is my code:
public class InfoActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.information);
MyPagerAdapter adapter = new MyPagerAdapter();
ViewPager myPager = (ViewPager) findViewById(R.id.mypanelpager);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
}
private class MyPagerAdapter extends PagerAdapter {
public int getCount() {
return 4;
}
public Object instantiateItem(View collection, int position) {
LayoutInflater inflater = (LayoutInflater) collection.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int resId = 0;
switch (position) {
case 0:
resId = R.layout.farleft;
break;
case 1:
resId = R.layout.left;
break;
case 2:
resId = R.layout.middle;
break;
case 3:
resId = R.layout.right;
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 void finishUpdate(View arg0) {
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
@Override
public void restoreState(Parcelable arg0, ClassLoader arg1) {
}
@Override
public Parcelable saveState() {
return null;
}
@Override
public void startUpdate(View arg0) {
}
}
}
The R.layout.right is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="@drawable/info4"
android:contentDescription="@string/fourthInfoImage">
</ImageView>
</LinearLayout>
And the others are equals except for the source image. How can I correct this error? There are several post about that error, but I didn't find the one that resolves my problem. I believe that the "destroyItem" function isn't called..
Thanks
P.S. Actually I follow the tutorial on http://mobile.tutsplus.com
