调用

（（ViewPager）container.addView（imageView，0）两次。
您调用
（（ViewPager）容器）。添加视图（imageView，0）两次

imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);

((ViewPager) container).addView(imageView, 0);

File photos= new File(POIImages.get(position));
iconBitMap = decodeFile(photos); iconBitMap = Bitmap.createScaledBitmap(iconBitMap,150, 150, true);

imageView.setImageBitmap(iconBitMap);


((ViewPager) container).addView(imageView, 0);**//Remove this line of code.**

imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);

((ViewPager) container).addView(imageView, 0);

File photos= new File(POIImages.get(position));
iconBitMap = decodeFile(photos); iconBitMap = Bitmap.createScaledBitmap(iconBitMap,150, 150, true);

imageView.setImageBitmap(iconBitMap);


((ViewPager) container).addView(imageView, 0);**//Remove this line of code.**
