评论
我看到一些其他的线程，但他们哪里都不有益的，或者至少不可以在我的情况下实施。
任何想法如何克服这个问题？
答
你应该看看这篇关于android dev网站http://developer.android.com/training/displaying-bitmaps/index.html的文章。你应该异步加载位图，因为你的解码文件，其昂贵的操作，你也应该先加载位图的尺寸和比它扩展到的imageview的
答
你应该使用这个真实大小......
@Override
public Object instantiateItem(ViewGroup container, int position) {
final TouchImageView imgDisplay;
inflater = (LayoutInflater) _activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View viewLayout = inflater.inflate(
R.layout.layout_fullscreen_image, container, false);
imgDisplay = (TouchImageView) viewLayout
.findViewById(R.id.imgDisplay);
final ProgressBar spinner = (ProgressBar) viewLayout
.findViewById(R.id.loading);
// btnShare = (Button) viewLayout.findViewById(R.id.btnShare);
imageLoader.displayImage(_imagePaths.get(position).get("url"),
imgDisplay, options, new ImageLoadingListener() {
@Override
public void onLoadingStarted() {
spinner.setVisibility(View.VISIBLE);
}
@Override
public void onLoadingFailed(FailReason failReason) {
String message = null;
switch (failReason) {
case IO_ERROR:
message = "Input/Output error";
break;
case OUT_OF_MEMORY:
message = "Out Of Memory error";
break;
case UNKNOWN:
message = "Unknown error";
break;
}
Toast.makeText(FullScreenViewActivity.this,
message, Toast.LENGTH_SHORT).show();
spinner.setVisibility(View.GONE);
imgDisplay
.setImageResource(android.R.drawable.ic_delete);
}
@Override
public void onLoadingComplete(Bitmap loadedImage) {
spinner.setVisibility(View.GONE);
Animation anim = AnimationUtils
.loadAnimation(FullScreenViewActivity.this,
R.anim.fade_in);
imgDisplay.setAnimation(anim);
anim.start();
}
@Override
public void onLoadingCancelled() {
// Do nothing
}
});
((ViewPager) container).addView(viewLayout, 0);
return viewLayout;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((FrameLayout) object);
}
}
添加在onCreate（）方法这个代码..
private DisplayImageOptions options;
options = new DisplayImageOptions.Builder()
.showImageForEmptyUri(R.drawable.ic_launcher).cacheOnDisc()
.imageScaleType(ImageScaleType.IN_SAMPLE_INT).build();
添加通用图像装载机-1.6.1-与-src.jar jar文件到您的库文件夹。
UPDATE：
private DisplayImageOptions options;
public FullScreenImageAdapter(Activity activity,
ArrayList<String> imagePaths) {
this._activity = activity;
this._imagePaths = imagePaths;
options = new DisplayImageOptions.Builder()
.showImageForEmptyUri(R.drawable.ic_launcher).cacheOnDisc()
.imageScaleType(ImageScaleType.IN_SAMPLE_INT).build();
}

我会尝试它现在Piyush！ – AndroidKrayze

Piyush，我的类扩展适配器，不是一个活动，所以这意味着我没有一个onCreate方法。 – AndroidKrayze

您也可以将它添加到您的Adapter类构造函数中。 – Piyush

如果有人试图从sqlite的图像和获取内存不足错误尝试以下操作：
cursor = adapter.getAllrecords(); //get your table records in cursor
//moving to the current position in cursor
cursor.moveToPosition(position);
byte [] image = cursor.getBlob(cursor.getColumnIndex("image"));
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
bitmapImage = BitmapFactory.decodeByteArray(image, 0, image.length, options);
imageView.setImageBitmap(decodeSampledBitmapFromResource(80, 80));//pass height and
//width as per your requirement
public int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int
reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height/2;
final int halfWidth = width/2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight/inSampleSize) > reqHeight
&& (halfWidth/inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
public Bitmap decodeSampledBitmapFromResource(int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true
to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(image, 0, image.length, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeByteArray(image, 0, image.length, options);
}
这段代码根据开发商guideliness工作了me..however我们应该使用AsyncTask处理与图像相关的任务...我们不应该在UI线程上运行它。
答
如果谷歌文档没有帮助（他们有一些巧妙的技巧），作为最后的手段，你可以尝试添加 android:largeHeap="true"在AndroidManifest.xml的<application>标签。但真的，最后的手段。
你可以使用通用imageLoader类..... – Piyush
那么这是在全屏幕活动实施？我现在正在实施相同的事情，并为我工作得很好。 – Piyush
它很奇怪，因为我自己运行此功能，它工作正常，但是当我将它合并到我的应用程序，我得到内存错误.. – AndroidKrayze
