我在我的應用程序中實現了一個使用ViewPager的活動,並使用PagerAdapter顯示4個圖像。您只能看到一個圖像,並顯示下一個您必須刷卡。 圖像的大小不是很大,我不知道爲什麼,但發生錯誤「java.lang.OutOfMemoryError位圖大小超過虛擬機預算pageradapter」。如何處理java.lang.OutOfMemoryError位圖大小超過虛擬機預算pageradapter?
這是我的代碼:
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) {
}
}
}
的R.layout.right是:
<?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>
,其餘的是除了源圖像等號。 我該如何糾正這個錯誤?關於這個錯誤有幾個帖子,但我沒有找到解決我的問題的那個。我相信「destroyItem」功能不叫..
謝謝
