抱歉我的语言.谢谢.
count = image_cursor.getCount(); thumbnails = new Bitmap[count];
可能导致这个.要创建位图内存效率,您应该使用BitmapOptions
试试这个：
Bitmap bm; bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile(filepath),100,truE); mPicture = new ImageView(context); mPicture.setImageBitmap(bm);
看到
Strange out of memory issue while loading an image to a Bitmap object
看起来这两个日志可能会给你提示：
.
你的画廊是否包含很多大图片？
在这种情况下,您的cursor没有问题,但在位图方面您的内存管理问题！
此外,您应该在清单中拥有此权限：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
也可以看看
